The newspaper industry has long been concerned that it is losing the young reader. The research informing this concern is derived largely from cross-sectional studies. We argue that younger people become older, stable, newspaper readers and that a cohort analysis approach is needed to understand this phenomenon.
We look at newspaper readership and its predictors both cross-sectionally and through cohort analysis in the 25-year cumulation (1972-1996) of the General Social Survey. We conclude that cohort analysis is a useful tool for understanding how young people age into the newspaper reading habit.
Are Young People Reading the Newspaper? A 25-Year Cohort Analysis -
Are Young People Reading the Newspaper? A 25-Year Cohort Analysis
Introduction A notion exists among today's newspaper editors and publishers that newspaper reading among young adults has declined dramatically throughout the past two to three decades. An outgrowth of this idea is the concern that if the newspaper industry does not reach these young people now, it will lose them as readers forever. Industry researchers have suggested that publishers target younger audiences in order to attract them to the newspaper, asserting that if young people do not pick up the paper now, they never will. In order to attract the younger reader, news organizations have tried a variety of tactics. These include re-design, in which more color and graphics, bigger headlines and shorter stories are incorporated into the newspaper; writing types of stories that represent teenagers, students and "gen x-ers"; and special sections designed for young adults. These tactics seem to have had limited success. The younger audience, in general, is still not flocking to the newspaper for information. Our premise is that they never have. The argument we develop here is two-fold - conceptual and methodological. First, a conceptual idea: Young people have never read the newspaper, at least at the levels attributed to older readers. We suspect newspaper reading habits are acquired later in life, say, in a person's 30s. We argue that while the young reader has historically reported lower newspaper reading levels than older people, as a person ages, his or her newspaper reading levels increase and level off. Publisher attention, then, might be more appropriately directed to nurturing the interest of older readers. Second, a methodological idea: Publishers' concerns have been largely informed by a cross-sectional, one-shot survey approach to analysis. Cohort analysis, with its potential to inform through the aging process, might usefully add insight to the debate. Our concern is that reliance on cross-sectional data alone may lead to self-fulfilling prophecies of panic regarding the fate and future of young readers while denying a role for maturation in the development of newspaper readership. Cohort analysis can give us access to such maturation processes. Our data come from a 25-year cumulation of the National Opinion Research Center's annual General Social Survey (GSS). The data extend from 1972 to 1996, offering immediate opportunities for the inter-generational study of newspaper readership and its prediction. Continued funding of the GSS might eventually allow for the study of media use through lifetimes. Using both cross-sectional and cohort approaches we consider two research questions: What has been the pattern of newspaper readership in three different age groups (18-29, 30-45, 46-89 years) over the past 25 years, and what role have education and television viewing played in newspaper readership through the period? The paper first reviews previous literature on newspaper readership and identifies reasons why young people might not read the newspaper as often as older people do. We point out that this literature is based largely on cross-sectional analyses and we propose that a cohort analysis approach might qualify and supplement the extant literature. We then examine Americans as they age and consider how and why newspaper reading levels might increase during this aging process. The study relies primarily on graphic displays to support its argument, with some statistical analyses (correlation and regression) provided to clarify differences and predictions. Our expectation is that we will find that young readers differ more in degree than of kind from older readers. We do not doubt that newer media pose important change problems for older media, but we expect the addition of a cohort approach to analysis will encourage thinking in a longer time frame rather than the immediate action called for by apocalyptic pronouncements, which are informed largely by cross-sectional analysis.
Review of Literature
Studies on newspaper reading habits have shown a decline in newspaper readership among all age groups in the past 30 years with young people (those under 30) showing consistently lower levels of newspaper reading than older people (Cobb, 1986; Glenn, 1994; Kirsch, Jungeblut, & Rock, 1988; Robinson, 1978; Stone, 1987; Times Mirror, 1990a & b). The data for younger readers have sometimes been interpreted in apocalyptic terms: If the newspaper industry does not reach young people now, it will lose them as readers forever (Carter, 1994; Fitzgerald, 1990). The literature is derived almost entirely from cross-sectional studies in which surveys are launched for one or two years at most and comparisons are made across age categories within the same study. An assumption can arise from such analyses - that as they age, the behavior of younger respondents will mimic that of the older age categories reported in the same study and year. The reality is that this younger age group will age into older age group categories at some later date beyond the scope of the study under review. And the older age groups reported on in the same study will have been in a younger age category at a point in time earlier than the study reports. Evidence regarding aging, and changes in media use consistent with that aging, can be better acquired through cohort analysis. Cohort data may show that change through time is a more gradual phenomenon than change across age categories at the same time, which is what cross-sectional data provide. Further, cross-sectional data can be acontextual. They are developed ad hoc in response to crises perceived by sponsors. They arise, then, in unique contexts, for example as an information-gathering tool during a perceived decline in newspaper readership in a particular demographic. Decisions might be taken based on such data. But the impact of these decisions beyond the crisis is problematic because such issues as aging have not been appropriately addressed. Indeed, the irony is that age as a category has been identified and considered, but aging as a phenomenon cannot be addressed in such studies because of their cross-sectional nature. Exhibit 1 offers a graphic display locating the more important newspaper readership studies across time. The studies are imposed on time series of cross-sectional studies divided into three age groups. The data are from the GSS cumulated data that is the basis of the present study. Apart from locating the newspaper literature in time, our point in Exhibit 1 is to illustrate the idea that cross-sectional analyses can be acontextual with regard to time. With the exception of Glenn's (1994) cohort analysis of newspaper reading, television viewing and verbal ability, all of the studies identified in Exhibit 1 are cross-sectional in approach. Each of the studies is linked in our rendering directly with the youngest age group, 18-29 years. In most cases this was the age group the studies were concerned with. Most also report on newspaper use in older age groups as well. ______________________ Exhibit 1 about here
Yankelovitch, Skelly and White's two studies (1976a & b) appear in Exhibit 1 to have been executed in the middle of a precipitous decline in young people's readership. Can the plateau in readership following from 1977 to 1986 be attributed to strategies suggested by Yankelovitch et al? From this plateau, Robinson's 1978 study asserts there has been no decline in young people's (18-24 years) newspaper reading in the 1965-1975 decade. Our GSS readership measure would suggest otherwise. Robinson's 1980 study asserts the greatest decline in postwar readership appeared in the 20-29 age group. Our data extend back to 1972. But we will attempt to make the case that there is no issue of greater or lesser rates of decline between age groups. We will assert that all age groups show similar rates of change. Cobb (1986), writing from the tail-end, in our terms, of a plateau in young people's readership levels found a slight decline in overall newspaper readership between 1961 and 1984, but that the decline had been about the same in all age groups. A short-lived increase followed her publication date. Stone (1987) reported that industry research had noted that between the years 1967 and 1974 newspaper readership declined four percent among all adults, and ten percent among "young people" (18-24 year-olds). Consistent with our data in Exhibit 1, Stone reported that newspaper readership among young adults "leveled off" in the 1980s. The exhibit also shows it went into a decline from 1987 through to 1991. Kirsch et al (1988), like Yankelovitch et at (1976a & b) before them, appear caught on a downward trend in young people's readership which raises questions about the longer term validity of the data they report. Times Mirror (1990) report on relative readership levels by age over several years, but their study was executed and published in a brief "oasis" in the middle of a period when readership levels of young adults appeared to show a substantially greater rate of decline than that for older age groups. Bagby (1991) reported a prediction by newspaper design expert Mario Garcia that in "about four or five years _ the transformation toward reader-driven newspapers will be complete" (p. 23). Five years from 1991 is 1996, and the tail-end of Exhibit 1 is not very encouraging towards Garcia's "reader-driven" newspaper. The cross-sectional data in Exhibit 1 do suggest a decline in overall readership levels from 1972 to 1996. Our grand mean decreases by nearly 10 percent over the period, but that is also about the same level as the standard deviation of the grand mean's variation though the period. Again, we will assert that the data for young people will show the same rates of change as do those for other age groups. The data in Exhibit 1 do tend to confirm this consistency in decline, but the graph for young people (18-29 years) does appear to show considerably more variation than do those for the older age groups. Young people appear to read the newspaper at significantly lower levels than that for older people, but we assert that the decline in their readership has matched that of older Americans. In other words, the differences between younger and older readers may be more one of degree than of kind. From this perspective, the task for publishers is to change the "degree." All this might require is patience - waiting for younger people to become older. Younger media consumers, while somewhat interested in news, are generally more apt to look to media other than the newspaper to find specific topics that interest them (Cobb, 1986). While they may occasionally pick up a newspaper for sports or entertainment or the comics, the mainstream newspaper - which focuses on political, economical, community and business issues - is not a resource the younger reader turns to on a regular basis. It does not "speak" to them. The older reader, on the other hand, is more likely to want a resource that provides information about a broad range of topics, from economic and political issues, to crime and human-interest stories - the kinds of material that a newspaper might offer (Stone & Boudreau, 1995). Knowing this, it may be more important for newspaper executives to target the age group that is beginning to read the newspaper on a regular basis - those in their early 30s. Most newspaper readership studies show young people reporting lower newspaper reading levels than that for older people. For instance, a Times Mirror survey (1990b) concluded that among 18-30 year olds, 40 percent read the newspaper. The findings were offered for decades, showing roughly a 10 percent increase in newspaper readership with each decade. For example, of 31-40-year-olds, roughly 50 percent read the newspaper; of 41-50-year-olds, 60 percent read the newspaper. In studies that attempt to look at trends in cross-sectional data across time, most conclude there has been a decline in newspaper reading levels among all people, with many researchers suggesting that the decline has been most drastic for younger readers. Some, if not all, newspaper executives view this as a continuing and relentless trend that will lead to a greater decline in overall newspaper reading (Bagby, 1991; Carter, 1994; Gersh, 1990; Fitzgerald, 1990). Research by the American Society of Newspaper Editors (ASNE) has fueled this sense of urgency to attract younger readers (McGrath, 1995). A 24-page booklet titled "Beyond Survival: Keys to Forging Ties With Potential Readers," was distributed to all ASNE participants outlining ways in which publishers can restructure their papers to suit younger readers. A wave of readership studies in the early 1970s spawned more alternative presses and "reader-friendly" mainstream newspapers containing a lot of photographs and graphics to attract the younger reader. All this activity seemed to have limited success. Robinson (1978), using results from national polls conducted in 1975-76, found no decline in newspaper use among people aged 18-24 during those years, but he did find a decline among older age groups of up to 13 percent. In his 1980 study using GSS data, Robinson found that among those aged 20-29, there was a 22 percent drop in newspaper readership. For those aged 30-39, there was a decline of 20 percentage points - a two percentage point difference. Robinson (1980) suggests that newspapers' strategies in the 1970s failed to "address the greatest source of attrition - the older reader." Industry leaders today worry that young people who do not read the newspaper will never acquire the habit and that targeting that audience is the best way to attract the young person to the newspaper. But the literature has suggested that reaching out to the young reader might not work. Perhaps the steady newspaper habit of older people should be the industry's main focus. Although we do not develop the argument here, perhaps undue attention to the younger reader may even alienate older readers. So why is the industry so concerned with reaching the younger reader? Cross-sectional studies appear to show bigger declines in young people's newspaper reading levels than those of older groups. We have noted from Exhibit 1 that this might not be the case, though it would appear that the younger newspaper reader does show more variation in their readership than do older age groups.
The Young Media Consumer
Younger Americans historically report being turned off by the newspaper, and the literature offers several reasons why. Yankelovitch et al (1976a & b) identified some of the reasons why young people do not read the newspaper in what they call "the balance sheet," a diagram from Part 1 (1976a) of their massive study funded by the Harte-Hanks newspaper chain. They assert that young people feel the newspaper is not relevant in their lives and that it does not interest them. They also found that young people find the newspaper boring, have little time to read it, think the newspaper has too much information they don't want and too little they do want, never picked up the newspaper reading habit, and only read the newspaper when they need it. In Stone's 1987 review of research about newspapers, other reasons why young people are turned off by the newspaper include lifestyle considerations, competing media, and the fact that young people are less settled than older people. Content preferences, however, seem to prevail. "There is something about the newspaper itself that has become a turn-off for young adults" Stone notes (1987, p. 122). He cites studies in which younger people said newspaper reading is an "old people's habit _ something you see old people do while waiting for a bus"; that they believe newspapers "speak for the status quo and against change in society"; are cold and impersonal; and a "middle-aged product written and edited by middle-aged people for a middle-aged audience" (p. 122). Aleff (1995) found that young people do not trust the media, and think news is too negative and irresponsible. Our first research question proposes testing for the perceived decline in young people's newspaper reading levels by examining data on reported newspaper reading levels. The question also proposes examining how this apparent decline compares to that for older age groups. This phase of the study will consider the issue with cross-sectional data. Research Question 1: Does newspaper reading among 18-29 year-olds change, in cross-sectional terms, through the period from 1972 to 1996, and does it differ from that of other age groups?
Aging Americans' Newspaper Reading Levels As people age their newspaper reading levels typically increase. The literature suggests that older age groups consistently show higher newspaper reading levels than do younger age groups. There are several reasons why this might be so. We address here ideas of "settling down" as implied in the aging-stability and community ties hypotheses, and the role of education. We also discuss a competing hypothesis that as the population ages it watches more television and that this increase in viewing might work against increases in newspaper readership. As people age, attitudes and behaviors tend to stabilize. This phenomenon has been referred to as the aging-stability hypothesis (Alwin, Cohen & Newcomb, 1991; Glenn, 1994). As people age, they also become less mobile and more settled. As they settle people develop community ties and subscribe to the newspaper more often (Demers, 1996; Stamm, Emig & Hesse, 1997). Because people generally settle down after college, this suggests a higher rate of readership by older, better educated, individuals (Reina, 1995). Further, those with children in school tend to subscribe more often to the newspaper than do younger, single people (Demers, 1993). The newspaper can be an important source of information for these kinds of people, providing news about crime, community, politics and economic issues. Times Mirror (1990) found that those who are well educated are more likely to read the paper than those who are less well educated. The study, in which nearly 4,900 people were interviewed, found that 55 percent of college graduates read a daily newspaper; of those with some college education 41 percent reported reading a daily newspaper; 41 percent of those with a high school diploma and 34 percent of those with less than a high school diploma read a daily newspaper. Poindexter (1979) and Westley and Severin (1964) found non-readers are less educated than those who read a newspaper regularly. Because young people are more mobile, less educated and have more varied lifestyles than the older audience, this should be an indication that the newspaper is not a resource that they regularly turn to. But as people mature, their interests change and the newspaper becomes a valued resource of information. The role of competing media on newspaper reading levels is less clear, if only because the diversity of these media has left the question unsettled. We consider only television here. The Roper research organization claimed that television first surpassed newspapers in 1963 as the public's preferred medium for news (Roper, 1964; but see Rimmer & Weaver, 1987; Stempel, 1991). Times Mirror (1990) concluded that in each age category (by decades), television news watching was at least ten percentage points higher than newspaper reading among all people interviewed. Poindexter (1979) found that the main reason given for not reading the newspaper was because the respondents got their news from the television. Sixty percent of her non-readers said they got their news from the TV. There is a notion abroad of late that the Internet is, or will soon be, the top resource for news. The literature suggests that younger people do turn elsewhere to get information that interests them. It has not been shown that that medium is the Internet. General television viewing (i.e., non-news viewing) is negatively associated with education and with newspaper reading (Comstock, Chaffee, Katzman, McCombs & Roberts, 1978). We might conclude, then, that television viewing levels will be negatively associated with newspaper reading levels. If the typical American daily newspaper reader is one who is older, better educated, and more settled into his or her community (Reina, 1995; Stamm et al., 1997; Stone, 1987), it would seem likely that even with cultural, environmental, and technological changes, young people will grow into the newspaper reading habit. This is the idea informing our second research question. The question explores newspaper reading levels as people age through time and how education and television might be associated with this newspaper reading. This question can be explored using cohort analysis.
Research Question 2: What is the pattern of reported newspaper readership in different age cohorts from 1972 through 1996? a. Does the 18-29 year-old cohort show an increase in levels of newspaper reading as it ages and how do the other age groups change as they age? b. What have been the roles of education and television viewing as predictors of newspaper reading?
Method
This study involves the secondary analysis of extant data. The data come from a cumulation of the General Social Survey (GSS), an annual survey conducted by the National Opinion Research Center since 1972 (Davis & Smith, 1994). The surveys are designed as part of a program of social indicator research, replicating questionnaire wording in order to facilitate time trend studies. The cumulation here extends from 1972 to 1996. There was no GSS survey in 1979, 1981, 1992, 1995 and 1997. The data reported here involve face-to-face personal interviews with people representing the total non-institutionalized English-speaking population of the United States, 18 years and older. The sample size each year is about 1,500, with a total population in the data set reported here of more than 35,000 respondents. The samples are probability samples: block quota sampling was used in 1972-74 and for half of the 1975 and 1976 surveys. Full probability sampling was employed in 1977, 1978, 1980, 1982-1991, 1993-1994, 1996 and half of the 1975 and 1976 surveys. A Black oversample was taken in 1982 and 1987. The oversample in 1982 was 354 persons beyond the average of 140 Blacks reported in the 1972 through 1982 samples. In 1987 it was 353 beyond the average 170 Blacks in samples from 1983 through 1987. We did not adjust for this oversampling in the present analysis. Given lower education levels in such subsamples we might expect to see lower newspaper reading levels and higher television viewing levels in the data for 1982 and 1987. The GSS went into the field every two years in 1994 and 1996 following a change in sampling and surveying strategy. Sample sizes were dramatically increased to facilitate split sample survey practices. The sample sizes in 1994 (n=2992) and 1996 (n=2904) were twice the size of previous surveys. We did not adjust for this change in sample size. We assumed standard errors would be reduced with the larger sample sizes but felt this would have little impact on our findings. This study uses four variables from the GSS: Our dependent variable is a five-point report of newspaper reading. Our independent variables are: Age (in years), education (years of schooling completed), and TV viewing (hours per day respondent watches television). The age and education questions are available for every year. The newspaper reading question was asked in the years 1972, 1975, 1977-1978, 1982-1983, 1985-1991, 1993-1994 and 1996. The TV viewing question was asked in 1975, 1977-1978, 1980, 1982-1986, 1988, 1989-1991, 1993-1994. The TV viewing question was not asked of the Black oversample in 1987. Question wording for most of our variables was the same each year. For example, the newspaper reading variable was consistently asked for as: "How often do you read the newspaper?" The answers are "every day," "a few times a week," "once a week," "less than once a week," "never." In the GSS, the answers are coded so that 1= "every day" and 5= "never." For this study, the codes were reversed so that 1= "never" and 5= "every day." The variable was treated as interval. For the age category, the question was changed after 1975 from "In what year were you born?" to "What is your date of birth?" For television viewing hours, the question wording in all years is, "On the average day, about how many hours do you personally watch television?" The answers are from 0 to 24. For the education variable, several questions were asked about level of schooling completed. The answers are 0 to 20 years. We assumed a consistent pattern in the response set. This study uses cohort and cross-sectional analyses. Cohort analysis is a longitudinal study approach which lends itself to prospective research. Cross-sectional research is more in the nature of the one-shot, retrospective, study. A cross-sectional study is one in which data are collected from a representative sample at only one point in time (Wimmer & Dominick, 1997). Where data are broken out by age, for example, comparisons between age groups are made at one point in time, across the one data set. A cohort analysis is one in which a characteristic of one or more age cohorts is compared at different points in time (Glenn, 1977; Ryder, 1968). It might be seen as a repeated cross-sectional study in which the analyst increments the groups of interest year by year through the data. It is not a panel study where the analyst returns to the same respondents. In cohort analyses, the analyst returns to the same classes of respondents. Our "base cohort" is a group of young adults who are between the ages of 18 and 29 in the first year of our study, 1972. We call our cohorts "age cohorts" because we are grouping them together by age and using their age as a descriptive. Other authorities refer to cohorts as "birth cohorts" because they label their cohorts according to their year of birth (Glenn, 1977). The concept is the same in both instances. Exhibit 2 graphically illustrates some of the differences between cross-sectional and cohort data as viewed in our study. ______________________ Exhibit 2 about here
The upper line in the graph is a report of mean newspaper reading scores for the 18-29 year-old age cohort. The lower line is the mean newspaper reading score for the cross-sectional 18-29 year-old age group. The cohort line indicates a 1972 start for the cohort, which ranges in age from 18 to 29. It might help to consider the line itself as a mean age of 24 representing the cohort. Each year the cohort ages one year through the 25 years through to 1996. The cross-sectional line is a report of mean newspaper reading for the 18-24 age group in each year through the 25 years of the study. So, the cross-sectional group's age stays at 18-29 throughout the 25 years of the study, whereas the cohort ages year by year. In this exhibit, the differences between the two lines are substantial. The cross-sectional data show a decline over the 25 years from highest to lowest of about 17 percent. The cohort data show a decline from highest to lowest value of about half that: eight percent. An inspection of the graph suggests the cross-sectional data do show a decline, whereas the cohort data show no real change from 1972 through 1996. In this study, we take cohort groups of interest and age them through the data. Comparisons within cohorts are intra-cohort, comparisons between cohorts are inter-cohort. The intra-cohort study is similar to a panel study, in which the same people are compared at different points in time. The difference is that the cohort study compares a sample of individuals, not the same individuals. The panel study examines individual changes, while the cohort study looks at trends (Glenn, 1977). The advantages of using cohort analyses are that one group can be tracked through time and subsequently trends of a population can be asserted by generalizing the reported behaviors of the cohort group. Cohort analyses are typically examined through charts and graphs, which show three types of effects: age effects, cohort effects and period effects. Our interest here is in age effects - the effect of age on levels of newspaper reading. However, in this type of analysis, age, period and cohort effects are confounded with one another. This problem in cohort analysis has been referred to by Glenn (1994) as the "age-period-cohort conundrum" and by Mason and her associates (Mason, Mason, Winsborough & Poole, 1973) as the "confounding" of the joint effects of aging, period and cohort effects. Glenn (1994) explains the conundrum as follows: "Since each of the three variables is a perfect linear function of the other two, linear effects of the variables are confounded with one another in any relevant data, whether they are cross-sectional, longitudinal or repeated cross-sectional" (p. 220). Exhibit 3 illustrates how the three variables can entangle each other in this age, period, cohort conundrum. ______________________ Exhibit 3 about here
Exhibit 3 is a combination plot of three measures for the 18-29 year-old cohort: newspaper reading, education, and television viewing. The age, period, cohort conundrum might be illustrated with the following question: "Why does mean education show an increase through the 25 years of the data? Shouldn't it be level?" Education shows a steady increase from grade 12.5 in 1972 to grade 14 in 1996. Some of the younger members of the cohort were likely still pursuing their formal education early in the study and that might help explain the increase through the first half of the study. Call this an age effect. But education continues to increase after this. Perhaps there is a problem in the way GSS built its samples, such that the mean education of the sample increased through the study. Perhaps education levels have increased in the population through the period 1972-1996 such that we are a better educated society? Call this a period effect. Perhaps the cohort has changed in makeup through the course of the study? More women and minorities are coming to the GSS each year better educated than before. This is reported in the study as an increase in level of education of the cohort. Call this a cohort effect. So, again, why does education appear to show an increase in Exhibit 3? A first glance might suggest the cohort is better educated as it ages through 1996. But this apparent increase is deceptive. The standard deviation for the cohort is nearly two grades, more than the apparent increase shown in the exhibit. This variation probably obscures any period effect. The apparent increase, then, may be due to the entangled age, period and cohort effects. Or worse, the increase we think we see may not be real at all. Glenn (1994) suggests that disentangling the conundrum requires the introduction of external data streams to the analysis. We do not have such data available to the present study. Preliminary analyses were executed in the statistical program SPSS. As a means of data reduction all cohort and cross-sectional data for newspaper reading, education and television viewing were reduced to mean scores for groups and for years. These means, their n's and standard deviations were transferred to Microsoft Excel spreadsheets. Graphing and the correlation and regression computations offered here were executed in Excel using the means as raw scores. Lag options were attempted in the regression computations. It would seem intuitive that education might not manifest itself as a predictor of newspaper readership immediately. Newspaper readership therefore was lagged in the regression computations from zero through two years. Serial correlation was not addressed in these computations. Where the GSS did not go into the field in particular years missing data were substituted using a smoothing technique. Scores from years surrounding missing years were averaged according to the number of missing cells in the interval. These constructed data provided cleaner looking graphs. These constructed data for missing years were excluded in statistical computations. No smoothing was effected in the graphing of substantive data runs. Smoothed grand means are offered in some graphs (e.g., in Exhibit 1). This smoothing was effected with a three-point moving average, typically iterated two to three times to deliver a useful smooth.
Results
In this section we first report some of the general characteristics of our data, then we describe the data associated with each of our three cohorts. Finally a series of exhibits and statistical tests are offered in association with the reporting of our analyses of the study's research questions. Exhibit 4 offers descriptive statistics for our three age groups and three variables of interest. Differences in the n's for the three variables are artifacts of the number of years the questions were asked. ______________________ Exhibit 4 about here
Exhibit 4 shows that the mean newspaper reading score was more than 3.5 for all of the age groups studied. More impressively, the mean newspaper reading score for all three age groups was greater than 3.4 in each year in the data. If a score of three means the respondent read the newspaper once a week, then the average person aged 18 to 29 reported reading the newspaper at least "once a week" to "a few times a week." So young people report they are reading the newspaper. They are just not reading newspapers as often as older Americans are. Further, the oldest age group (age 46-89 years) reported mean newspaper reading levels of at least 4.0 throughout the data, meaning this oldest group reported reading the newspaper at least "a few times per week" throughout the tested years. Our first research question dealt with the perceived drastic decline among the 18-29-year-old group. The question was as follows: Does newspaper reading among 18-29 year-olds change, in cross-sectional terms, through the period from 1972 to 1996, and does it differ from that of other age groups? The short answer is yes and yes. Exhibit 1 compares the mean newspaper reading scores of the three age groups from 1972 to 1996. Newspaper reading among the 18-29 year-old age does change - it shows a decline. The 18-29-year-old group started with a mean newspaper reading score of 4.07 in 1972 and ended with a score of 3.42 in 1996 - a difference of .53 (16 percent). In order to compare the rates of change between the three age groups a Pearson correlation was computed. No adjustment was made for any serial correlation. The correlation coefficients are offered in Exhibit 5. We speculated that a significant correlation between the age groups would indicate similar rates of decline, while no relationship would indicate the age groups were independent of each other. ______________________ Exhibit 5 about here
Exhibit 5 shows a strong positive correlation (r=.85, df=23, p<.05) between the 18-29 and the 30-45 year-old age groups, and a moderate positive correlation (r=.43, df=23, p<.05) between the 18-29 and the 46-89 year-old age groups. This indicates that the three age groups have tended to decline at about the same rate. We had earlier spoken of issues of degree and of kind. The correlation analysis suggests there is no difference in kind among the three age groups with regard to rates of decline. Exhibit 1, however, does indicate differences of degree. The 18-29-year-olds - the "young" group - show a consistently lower pattern than the older groups. Using a mean of the grand means in Exhibit 1 as our base (mean score 4.13) we find that the two older age groups cluster nearer to the grand mean (30-45 mean=4.14; 46-89 mean=4.23) than does the 18-29 year-olds with its substantially lower mean of 3.73.
Research Question 2 asked the following: What is the pattern of reported newspaper readership in different age cohorts from 1972 through 1996? Two additional questions were posed: a. Does the 18-29 year-old cohort show an increase in levels of newspaper reading as it ages and how do the other age groups change as they age? b. What have been the roles of education and television viewing as predictors of newspaper reading?
Exhibit 6 is an expanded plot of mean newspaper reading levels for our three age groups. ______________________ Exhibit 6 about here
Research Question 2 first asked about patterns of readership amongst the three cohorts. The general pattern is one of substantial differences in 1972 with convergence through 1996. A further characteristic of this general pattern is that the convergence is not one in which the two younger cohorts' newspaper reading levels moving up through time to the newspaper reading levels of the oldest cohort. Rather we see something more akin to a regression, in which all three cohorts converge to a more central level. This is not what we expected. We had assumed that reading levels would increase with age, and consistent with that idea was the assumption that the oldest age group would serve as the model toward which the younger cohorts would move. The rates of change are somewhat deceptive as offered in the expanded plots in Exhibit 6. A closer inspection of the vertical scale in the exhibit reminds us that the changes are not as dramatic as they might appear to be. Part a of Research Question 2 asked about patterns of readership in the 18-29 year-old cohort. For the purposes of interpretation, assume a mean age for the cohort of 24. By 1978 the cohort is aged 30 and at this point a gradual increase in newspaper reading is reported through to age 45 in 1993. This is consistent with our expectations that as people age their newspaper reading levels would increase. (The consistent drop in reading levels across all three cohorts for 1994 and 1996 is problematic so we choose not to incorporate it into the discussion here). Part a of the question also asked about patterns of newspaper readership in the other two cohorts. As we expected, the older age group (46-89 year-olds) showed the most consistency in levels of readership. We attribute the substantial dip in 1987 for this cohort to the Black oversample in this year. We had anticipated that the oversample might have some impact on newspaper reading. The most dramatic pattern is that for the 30-45 year-old cohort. It shows a substantial decline through the period. Again, for the purposes of interpretation, assume a mean age for this cohort of 38 in 1972. This group reports the highest reading levels near 4.6 in 1972. They age to 63 by 1996 and at that point report reading levels of about 4.1. Yet our data analyses show that across the data set as a whole, respondents aged 65 showed the highest levels of newspaper readership. The lower levels of readership reported by our 30-45 year-old cohort when they reach 63 years of age may be a reminder that this cohort is somewhat unique and should not be regarded as typical of all cohorts. We address this point further in our discussion section. Part b of Research Question 2 asked the following: What have been the roles of education and television viewing as predictors of newspaper reading? This question was resolved in two ways: graphically, and with a series of multiple regression computations executed on data from the 18-29 year-old cohort. Exhibit 3 shows a combination plot for the 18-29 year-old cohort of mean newspaper reading, television viewing and education. A caution: the ordinate (Y-axis) is a combination scale. A forced break has been introduced on the ordinate to accommodate the lower numerical values associated with television viewing and newspaper reading and the larger values associated with levels of education. The plot of newspaper reading in Exhibit 3 appears to be relatively static through the 25-year period of the study. Education shows an apparent increase through the period so we might expect it to be a positive predictor of newspaper reading. Television viewing levels show a decline in the plot, so we expect that if it is a predictor of newspaper reading it will be a negative predictor. Newspaper reading was regressed on education and television viewing in a series of lagged computations. We review here the zero, one- and two-year lags of newspaper reading. At zero lag the regression equation accounted for nearly 27 percent of the variance (R2= 26.75) in newspaper reading. Education was a significant predictor (Regression coefficient=.25, p<.05) but television viewing was not. The regression equation failed to reach significance when newspaper reading was lagged by one year, but did show significance when newspaper reading was lagged two years (R2= 50.86, Regression coefficients: Education=.37, p<.05, TV viewing=.39, p<.05). The finding that education in particular might have an impact on newspaper reading two years later is intuitively appealing. Given we did not address the issue of serial correlation in our analyses, however, this issue needs more work before any support can be claimed for the finding.
Conclusion
This study's goal was to better understand the newspaper reading behavior of young adults. We asked two general questions: What are the patterns of readership in cross-sectional and cohort-derived data for young readers and how might they differ from those of older age groups? We have found differences in the patterns between cross-sectional and cohort-derived data and between the readership behaviors of younger and older cohorts. These differences are such that we now feel ready to offer some preliminary conclusions to the industry. Differences are more of degree than of kind. We mean by this that younger readers do report reading the newspaper but at lower levels than do older age groups. Their newspaper reading does not appear to be so different in its patterns that we might venture it as a different kind of reading. This should be reassuring to the industry. Our expectation that younger people will come into the newspaper reading fold appears to be supported. The differences there are between cross-sectional and cohort data show up most dramatically with younger readers. Exhibit 2 shows this clearly with the diverging plots of cross-sectional and cohort data. Other plots we have done on the same data for the two older age groups show markedly less divergence. This suggests to us that cohort analyses can be most useful in understanding how younger people age into their 30s and the life stage that we have argued signals the beginning of stable newspaper reading. We have found the newspaper reading habit to be most stable in our oldest age group. So, cohort analysis might not be so useful a research tool with older age groups, at least with regard to newspaper reading. We have two recommendations for future research. Our first recommendation is to develop better measures and controls in the data we have worked with here. Our newspaper readership measure is a five-point variable we have treated as an interval measure. There is a need for more diversity in type and scale in the media use measures and their predictors in the GSS. Age might usefully be extended back beyond the GSS start of 18 years. The media behaviors we are interested in get their start long before respondents turn 18. GSS samples need to deliver more younger and older people. For example, across the 25 years of the cumulated data set there were just 115 18-year olds and 47 88-year olds. With regard to controls, several methodological issues arise that could be addressed in future research. We did not address the issue of serial correlation, or weighting for the oversampling and split sampling that characterizes many of the GSS surveys. And we did not consider a point Glenn reported he adjusted for in his 1994 cohort study - that the GSS samples by households rather than by individuals, yet it is individuals we are attempting to study. Our second recommendation is that we need to consider cohorts more as serial phenomena. In the present study we have evaluated just three parallel cohorts, all of which we started at one point in time, 1972. This narrow approach limits the potential that these rich GSS data have to offer. There is a need for future analysts to develop the facility to simultaneously analyze many cohorts over many years. Exhibit 7 might be seen as the beginnings of an attempt to address this idea. The exhibit shows newspaper readership data for single-year cohorts with starts at 18 years of age in 1962, 1972, and 1982, and ages these cohorts through the 25 years of the GSS data set. ______________________ Exhibit 7 about here
