Some observers have noted that the decline in social connectedness began just after the successes of the civil rights revolution of the 1960s. That coincidence has suggested the possibility of a kind of sociological "white flight," as legal desegregation of civic life led whites to withdraw from community associations.

The erosion of social capital, however, has affected all races. In fact, during the 1980s the downturns in both joining and trusting were even greater among African Americans (and other racial minorities) than among the white majority. This fact is inconsistent with the thesis that "white flight" is a significant cause of civic disengagement, since black Americans have been dropping out of religious and civic organizations at least as rapidly as white Americans.

Even more important, the pace of disengagement among whites has been uncorrelated with racial intolerance or support for segregation. Avowedly racist or segregationist whites have been no quicker to drop out of community organizations during this period than more tolerant whites.

This evidence is far from conclusive, of course, but it does shift the burden of proof onto those who believe that racism is a primary explanation for growing civic disengagement over the last quarter century. This evidence also suggests that reversing the civil rights gains of the last thirty years would do nothing to reverse the social capital losses.


Our efforts thus far to identify the major sources of civic disengagement have been singularly unfruitful. In all our statistical analyses, however, one factor, second only to education, stands out as a predictor of all forms of civic engagement and trust. That factor is age. Older people belong to more organizations than young people, and they are less misanthropic. Older Americans also vote more often and read newspapers more frequently, two other forms of civic engagement closely correlated with joining and trusting.

"Civic Engagement by Age" shows the basic pattern. Civic involvement appears to rise more or less steadily from early adulthood toward a plateau in middle age, from which it declines only late in life. This humpback pattern seems naturally to represent the arc of life's engagements. That, at least, was how I first interpreted the data. But that would be a fundamental misreading of the most important clue in our whole whodunit.

Figure 2."Civic Engagements by Age (education controlled)" shows civic engagement to increase with age. _______________________________________________________________________

Evidence from the General Social Survey enables us to follow individual cohorts as they age. If the rising lines in the figure indeed represent deepening civic engagement with age, we should be able to track this same deepening engagement as we follow, for example, the first of the baby boomers, born in 1947, as they aged from 25 in 1972 (the first year of the GSS) to 47 in 1994 (the latest year available). Startlingly, however, such an analysis, repeated for successive birth cohorts, produces virtually no evidence of such life cycle changes in civic engagement. In fact, as various generations moved through the period between 1972 and 1994, their levels of trust and membership more often fell than rose, reflecting a more or less simultaneous decline in civic engagement among young and old alike, particularly during the second half of the 1980s. But that downtrend obviously cannot explain why, throughout the period, older Americans were always more trusting and engaged. In fact, the only reliable life cycle effect visible in these data is a withdrawal from civic engagement very late in life, as we move through our eighties.

The central paradox posed by these patterns is this: Older people are consistently more engaged and trusting than younger people, yet we do not become more engaged and trusting as we age. What's going on here?

Time and age are notoriously ambiguous in their effects on social behavior. Social scientists have learned to distinguish three contrasting phenomena:

Life cycle effects represent differences attributable to stage of life. In this case individuals change as they age, but since the effects of aging are, in the aggregate, neatly balanced by the "demographic metabolism" of births and deaths, life cycle effects produce no aggregate change. Everyone's close-focus eyesight worsens as we age, but the aggregate demand for reading glasses changes little.

Period effects affect all people who live through a given era, regardless of their age. Period effects can produce both individual and aggregate change, often quickly and enduringly, without any age-related differences. The sharp drop in trust in government between 1965 and 1975, for example, was almost entirely this sort of period effect, as Americans of all ages changed their minds about their leaders' trustworthiness. Similarly, as just noted, a modest portion of the decline in social capital during the 1980s appears to be a period effect.

Generational effects affect all people born at the same time. Like life cycle effects (and unlike typical period effects), generational effects show up as disparities among age groups at a single point in time, but like period effects (and unlike life cycle effects) generational effects produce real social change, as successive generations, enduringly "imprinted" with divergent outlooks, enter and leave the population. In pure generational effects, no individual ever changes, but society does.

Returning to our conundrum, how could older people today be more engaged and trusting, if they did not become more engaged and trusting as they aged? The key to this paradox, as David Butler and Donald Stokes observed in another context, is to ask, not how old people are, but when they were young. The figure, "Social Capital and Civic Engagement by Generation," addresses this reformulated question, displaying various measures of civic engagement according to the respondents' year of birth.

Figure 3."Social Capital and Civic Engagement by Generation (education controlled)" shows an overall decline in social capital and civic engagement in the age cohorts that turned 18 after the 1940s. __________________________________________________________________________


In effect, the figure on the bottom of page 43 lines up Americans from left to right according to their date of birth, beginning with those born in the last third of the nineteenth century and continuing across to the generation of their great-grandchildren, born in the last third of the twentieth century. As we begin moving along this queue from left to right--from those raised around the turn of the century to those raised during the Roaring Twenties, and so on--we find relatively high and unevenly rising levels of civic engagement and social trust. Then rather abruptly, however, we encounter signs of reduced community involvement, starting with men and women born in the early 1930s.

Remarkably, this downward trend in joining, trusting, voting, and newspaper reading continues almost uninterruptedly for nearly 40 years. The trajectories for the various different indicators of civic engagement are strikingly parallel: Each shows a high, sometimes rising plateau for people born and raised during the first third of the century; each shows a turning point in the cohorts around 1930; and each then shows a more or less constant decline down to the cohorts born during the 1960s.

By any standard, these intergenerational differences are extraordinary. Compare, for example, the generation born in the early 1920s with the generation of their grandchildren born in the late 1960s. Controlling for educational disparities, members of the generation born in the 1920s belong to almost twice as many civic associations as those born in the late 1960s (roughly 1.9 memberships per capita, compared to roughly 1.1 memberships per capita). The grandparents are more than twice as likely to trust other people (50-60 percent compared with 25 percent for the grandchildren). They vote at nearly double the rate of the most recent cohorts (roughly 75 percent compared with 40-45 percent), and they read newspapers almost three times as often (70-80 percent read a paper daily compared with 25-30 percent). And bear in mind that we have found no evidence that the youngest generation will come to match their grandparents' higher levels of civic engagement as they grow older.

Thus, read not as life cycle effects, but rather as generational effects, the age-related patterns in our data suggest a radically different interpretation of our basic puzzle. Deciphered with this key, the figure on page 43 depicts a long "civic" generation, born roughly between 1910 and 1940, a broad group of people substantially more engaged in community affairs and substantially more trusting than those younger than they. (Members of the 1910-1940 generation also seem more civic than their elders, at least to judge by the outlooks of relatively few men and women born in the late nineteenth century who appeared in our samples.) The culminating point of this civic generation is the cohort born in 1925-1930, who attended grade school during the Great Depression, spent World War II in high school (or on the battlefield), first voted in 1948 or 1952, set up housekeeping in the 1950s, and watched their first television when they were in their late twenties.

Since national surveying began, this cohort has been exceptionally civic: voting more, joining more, reading newspapers more, trusting more. As the distinguished sociologist Charles Tilly (born in 1928) said in commenting on an early version of this essay, "We are the last suckers."

To help in interpreting the historical contexts within which these successive generations of Americans matured, the figure also indicates the decade within which each cohort came of age. Thus, we can see that each generation that reached adulthood since the 1940s has been less engaged in community affairs than its immediate predecessor.

Further confirmation of this generational interpretation comes from a comparison of the two parallel lines that chart responses to an identical question about social trust, posed first in the National Election Studies (mainly between 1964 and 1976) and then in the General Social Survey between 1972 and 1994.

If the greater trust expressed by Americans born earlier in the century represented a life cycle effect, then the graph from the GSS surveys (conducted when these cohorts were, on average, 10 years older) should have been some distance above the NES line. In fact, the GSS line lies about 5-10 percent below the NES line. That downward shift almost surely represents a period effect that depressed social trust among all cohorts during the 1980s. That downward period effect, however, is substantially more modest than the large generational differences already noted.

In short, the most parsimonious interpretation of the age-related differences in civic engagement is that they represent a powerful reduction in civic engagement among Americans who came of age in the decades after World War II, as well as some modest additional disengagement that affected all cohorts during the 1980s.

These patterns hint that being raised after World War II was a quite different experience from being raised before that watershed. It is as though the postwar generations were exposed to some mysterious X-ray that permanently and increasingly rendered them less likely to connect with the community. Whatever that force might have been, it--rather than anything that happened during the 1970s and 1980s--accounts for most of the civic disengagement that lies at the core of our mystery.

But if this reinterpretation of our puzzle is correct, why did it take so long for the effects of that mysterious X-ray to become manifest? If the underlying causes of civic disengagement can be traced to the 1940s and 1950s, why did the effects become conspicuous in PTA meetings and Masonic lodges, in the volunteer lists of the Red Cross and the Boy Scouts, and in polling stations and church pews and bowling alleys across the land only during the 1960s, 1970s, and 1980s?

Figure 4. "The Rise and Decline of a Civic Generation" shows that the civically-engaged generation born between 1911 and 1940 (and its sub-cohort born between 1921 and 1935) was at its greatest numerical concentration in 1960. __________________________________________________________________________

The visible effects of this generational disengagement were delayed by two important factors. First, the postwar boom in college enrollments raised levels of civic engagement, offsetting the generational trends. As Warren E. Miller and J. Merrill Shanks observe in their as yet unpublished book, The American Voter Reconsidered, the postwar expansion of educational opportunities "forestalled a cataclysmic drop" in voting turnout, and it had a similar delaying effect on civic disengagement more generally.

Second, the full effects of generational developments generally appear several decades after their onset, because it takes that long for a given generation to become numerically dominant in the adult population. Only after the mid-1960s did significant numbers of the "post-civic generation" reach adulthood, supplanting older, more civic cohorts. The figure "The Rise and Decline of a Civic Generation" illustrates this generational accounting. The long civic generation born between 1910 and 1940 reached its zenith in 1960, when it comprised 62 percent of those who chose between John Kennedy and Richard Nixon. By the time that Bill Clinton was elected president in 1992, that cohort's share in the electorate had been cut precisely in half. Conversely, over the last two decades (from 1974 to 1994) boomers and X-ers (that is, Americans born after 1946) have grown as a fraction of the adult population from 24 percent to 60 percent.

In short, the very decades that have seen a national deterioration in social capital are the same decades during which the numerical dominance of a trusting and civic generation has been replaced by the dominion of "post-civic" cohorts. Moreover, although the long civic generation has enjoyed unprecedented life expectancy, allowing its members to contribute more than their share to American social capital in recent decades, they are now passing from the scene. Even the youngest members of that generation will reach retirement age within the next few years. Thus, a generational analysis leads almost inevitably to the conclusion that the national slump in trust and engagement is likely to continue, regardless of whether the more modest "period effect" depression of the 1980s continues.
