Generations: The Real Differences Between Gen Z, Millennials, Gen X, Boomers, and Silents―and What They Mean for America's Future

Born between 1925 and 1945, the Silent Generation grew up amid the upheavals of the Great Depression, World War II, and the postwar era. The generation is often stereotyped as conformist and traditional, a transitional cohort between the celebrated “Greatest Generation” and the Boomers, who are more commonly associated with the social upheavals of the 1960s. Twenge challenges this view, presenting them as an often-overlooked generation positioned between older collectivistic norms and the rise of modern individualism. While they embraced the family-centric, collectivistic values of the 1950s and married at unusually young ages, they were far from silent on social issues.

Twenge argues that the Silents, not the Boomers, were leaders in several of the 20th century’s major equality movements. Their young adulthood coincided with the dawn of a new, individualistic ethos. Figures such as Martin Luther King Jr. and Ruth Bader Ginsburg belonged to the Silent Generation, and Twenge attributes much of the leadership of the civil rights, feminist, and early LGBT-rights movements to this cohort. In this way, Silents participated in challenging many of the social rules under which they had grown up. As Twenge writes, quoting Time magazine from 1951, “‘The most startling fact about the younger generation is its silence’” (33), a description that she argues became a misnomer as the generation entered adulthood.

By emphasizing the Silents’ role in these movements, Twenge challenges common assumptions about which generations drove the social changes of the 1960s. She distinguishes their contribution from that of the Boomers: Silents helped change laws and social rules, while Boomers later brought many of the counterculture’s values into mainstream American life. This distinction supports Twenge’s broader argument that generational influence can be obscured when major cultural changes are automatically associated with the generation most popularly identified with an era.

As the massive generation born after World War II, the Baby Boomers have exerted outsized influence on American culture at every stage of their lives. Twenge identifies them as the generation that accelerated what she calls the “Big Bang of Modern Individualism” (83), bringing many of the values associated with the Silents’ social movements into mainstream American life. Their rejection of the draft, embrace of premarital sex, and focus on self-fulfillment made individual choice increasingly central to American culture.

However, Twenge complicates the popular narrative that Boomers are a monolithic generation of privileged idealists who “delivered disaster” (80). She highlights two key contradictions. First, despite their association with the counterculture of the 1960s, their political identity shifted dramatically. The hippies of the 1960s became the yuppies of the 1980s, moving from overwhelmingly Democratic to majority Republican as they aged into their fifties, sixties, and seventies and becoming more Republican than previous generations were at the same age. Second, she argues that the Boomers were not the perpetrators of modern income inequality but its “first casualties” (140). The decline of manufacturing jobs and the widening gap between college-educated and non-college-educated workers began in the 1980s, dividing the generation economically and leaving many less-educated Boomers particularly vulnerable to declining economic and social well-being.

Ultimately, the Boomers illustrate what Twenge sees as the trade-offs of rising individualism. They broke down restrictive social norms and helped bring greater acceptance of individual choice into mainstream culture, but Twenge also connects growing individualism during their lifetimes with greater self-focus, less stable relationships, and heightened expectations for personal fulfillment. Their experience therefore establishes patterns that Twenge traces, in changing forms, through the generations that follow.

Sandwiched between the massive Boomer and Millennial generations, Gen X is the quintessential “middle child” of American generations—often overlooked but fiercely independent and resilient. Twenge defines them by their unique position straddling two worlds: They are the last generation to experience an analog childhood and the first to enter young adulthood in the age of the internet. Twenge connects this dual experience with their independent, self-reliant, and often cynical outlook. 

Raised during a period of rising divorce rates, latchkey childhoods, and a violent crime wave, Gen X developed what author Meghan Daum calls a “sassy intrepidness” (165). They were the first generation to grow up fully immersed in the post-1960s individualistic culture, which they took not as a cause for rebellion but as a simple fact of life. Twenge shows this translated into self-confidence and materialism in the 1980s, countering the “slacker” stereotype of the 1990s.

A major trend Twenge identifies with Gen X is declining social trust. Their generation saw a sharp, sustained decline in trust in other people, while trust in government and the press also deteriorated during their formative years. Twenge connects this mistrust to broader changes including rising income inequality and individualism, and Millennials and Gen Z continued the decline in interpersonal trust that began with young Gen Xers. While their low voter turnout in young adulthood contributed to a reputation for political apathy, their participation increased as they aged. Gen X therefore occupies an important transitional position in Twenge’s account: They experienced an analog childhood before adapting to a digital adulthood, while the individualism and distrust that characterized their generation continued among Millennials and Gen Z.

Millennials came of age during an era of optimism, technological revolution, and the self-esteem movement. They were raised largely by Boomer parents within a culture that emphasized self-esteem and positive reinforcement. Based on available measures, Millennials are the most optimistic and self-confident generation in history, famously labeled by Time as the “Me Me Me Generation” (247). Twenge argues this was not their invention but an extension of decades of rising individualism. Their positive upbringing instilled high expectations, which collided with the reality of the Great Recession, creating disappointment as they entered adulthood.

A major part of Twenge’s analysis challenges the popular narrative that Millennials were economically “screwed.” While acknowledging the burdens of student debt and the 2008 financial crisis, she presents extensive data showing that, by their thirties, Millennials had higher household and personal incomes than Boomers and Gen X did at the same age. The perception of being economically “screwed,” she argues, stems from a combination of sky-high expectations, the distorting lens of social media, and a real class divide where non-college-educated members of the generation have been left behind.

Millennials also represent a substantial acceleration of the slow-life strategy, delaying marriage and parenthood longer than previous generations. At the same time, Twenge connects their individualism to a dramatic decline in religious affiliation and a rise in support for LGBT rights. These patterns illustrate several of the tensions Twenge identifies within the generation: Millennials achieved relatively high incomes while often perceiving themselves as economically disadvantaged, and the optimism and self-confidence of their youth later encountered the effects of the Great Recession and, according to Twenge, rising mental health problems as social media and political polarization intensified in adulthood.
