What are the primary generations of the 20th and 21st centuries?
Not everyone agrees on the exact name for each generation, nor do they agree on the precise year when each begins and ends. We’ve done our best to give estimates based on the sources we found.
Except for where other links are cited, we’ve gathered the following information from
The Lost Generation, came of age during WWI
- Mass production of the Model T
- World War I
- Prohibition
- Women’s right to vote
What are they known for?
People use the term “Lost Generation” to refer to those who entered adulthood around the time of WWI and who suffered loss or disillusionment as a result of the war. Brittanica says, “The generation was ‘lost’ in the sense that its inherited values were no longer relevant in the postwar world and because of its spiritual alienation from a United States that…seemed to its members to be hopelessly provincial, materialistic, and emotionally barren.”
The works of early twentieth century writers such as Gertrude Stein (credited with coming up with the generation’s name), Ernest Hemingway, F. Scott Fitzgerald, and T. S. Eliot captures the disillusionment and overindulgence of the members of this group.
The Greatest Generation (G.I. Generation)
- The Great Depression
- FDR’s New Deal
- WWII
- Pearl Harbor
What are they known for?
News anchor Tom Brokaw is credited with naming this group the “Greatest Generation,” but they are sometimes called the “G.I. Generation” because of their service in WWII. The members of this generation are known for their strong work ethic, high morals, and sense of duty. They tended to avoid divorce and debt. They built modern America by helping to develop its infrastructure and gave rise to the suburban middle class. The majority of them were religious, and there was a significant increase in the level of education during this time.
The Silent Generation (the Lucky Few)
- Post-War “American Dream”
- Korean War
- Space race/moon landing
- McCarthyism
- Cold War/bomb shelters
What are they known for?
Described by some as “‘grave and fatalistic,’” the Silent Generation is known for not wanting to go against the government or the “system.” They had higher employment rates than either the Greatest Generation or the Baby Boomers, but men’s and women’s roles were traditional, with women generally staying at home (88% were not in the workforce). Women also had children at an average younger age than any other generation. Men tended to stay at their jobs for their whole lives. Divorce and having children out of wedlock were taboo. This generation was characterized both by wealth and conformity. No member of the Silent Generation has ever been president.
Baby Boomers
- Vietnam War/protests
- Korean WarWatergate/Nixon resignation
- Woodstock
- Summer of Love
- JFK, Martin Luther King, Jr., Robert Kennedy assassinations
- TV
What are they known for?
The “Baby Boomers” get their name from the dramatic increase in the birth rate following World War II and are the only generation officially named by the U.S. Census Bureau. In contrast to the Silent Generation, the Boomers were willing questioners of authority. The time period when the Baby Boomers came of age was one of great social and cultural change in America. Besides the civil rights movement, there was the controversial Vietnam War, the sexual revolution, and the culture of rock and roll. Premarital sex and divorce became much more common. Even though many stayed at home, women started working outside the home more than ever before. Yet at the same time, Boomers tend to have a positive view of tradition and authority.
Generation X (Gen X)
- Fall of the Berlin Wall
- End of the Cold War
- AIDS crisis
- MTV/music videos
What are they known for?
Gen Xers come between two large generations and, compared to Boomers and Millennials, have less of a tendency to see themselves as unique. They often are stereotyped rather negatively as cynical and passive. They’re individualistic, motivated to learn, and have a lot of startup founders compared to other generations. They’re the first generation in which women had greater levels of education than men, and they are known for having a lot of personal debt. Many of the parents of Gen Xers were divorced or checked out due to being focused on their careers. Gen Xers have tended to marry later and divorce sooner than previous generations.
Millennials (Gen Y)
- 9/11
- Obama election
- Great Recession
- Rise of global internet
What are they known for?
In 2016, Millennials surpassed Boomers to become the largest living generation. Millennials show a greater aversion to labels and institutions compared to previous generations. They are less likely to identify with a political party, marry, join the military, or identify with a religion. They are known for being more optimistic than cynical and are three times as likely not to be married when compared with the Silent Generation at the same age. Millennial women are twice as likely to be in the workforce as women from the Silent Generation. It became much more common for Millennials to identify as LGBTQ+ compared to those in previous generations, and it also became more common for Millennials to continue living at home between the ages of 25 and 35. Millennials’ parents tended to be fairly involved in their lives and to praise their achievements.
Gen Z (iGen)
- Global terrorism
- Trump election/Brexit
- Social media natives
- YouTube/digital content
- Supreme Court ruling on same-sex marriage
What are they known for?
Gen Z is known for being anxious and hard-working. Some think they will end up being the most entrepreneurial generation. They’ve grown up in a world where everyone has a smartphone, there was a black president, and same-sex marriage is a constitutional right. Gen Z tends to see morals as relative and is growing up in a far more diverse world than previous generations have, both when it comes to race and gender identity. For example, MarketingTeacher.com reports that “Since the early 1700s, the most common last name in the US was ‘Smith,’ but not anymore; now it is Rodriguez.”
