[1] They generally adopt a slow-life history strategy in that compared to previous cohorts, they tend to be highly educated, be less inclined to engage in sexual intercourse, marry later, and have fewer children, or none at all.
A 2012 study by professors at Brigham Young University found that college students were more likely to define "adult" based on certain personal abilities and characteristics rather than more traditional "rite of passage" events.
"[41] Jonathan Rauch, senior fellow at the Brookings Institution, wrote for The Economist in 2018 that "generations are squishy concepts", but the 1981 to 1996 birth cohort is a "widely accepted" definition for millennials.
[46] The Pew Research Center defines millennials as born from 1981 to 1996, choosing these dates for "key political, economic and social factors", including the September 11 terrorist attacks, the 2003 invasion of Iraq, Great Recession, and Internet explosion.
[75] Surveys of high-school seniors and college freshmen of the early 2010s found that the proportion of students who placed a high value on wealth and who did not think it was important to keep abreast of political affairs grew, while the number of those who thought it was necessary to develop "a meaningful philosophy of life" fell compared to older generations.
[77][78][79] In any case, there is considerable evidence for Millennials being a highly self-focused cohort as American society at large continues to shift towards individualism, a trend observed in every generation born after the Second World War.
[2] A 2019 poll by Ypulse found that among people aged 27 to 37, the musicians most representative of their generation were Taylor Swift, Beyoncé, the Backstreet Boys, Michael Jackson, Drake, and Eminem.
This demographic reality puts the United States at an advantage compared to many other major economies as the millennials reach middle age: the nation will still have a significant number of consumers, investors, and taxpayers.
[105] According to a Bloomberg L.P., "Three and a half years after the worst recession since the Great Depression, the earnings and employment gap between those in the under-35 population and their parents and grandparents threatens to unravel the American dream of each generation doing better than the last.
"[106] Despite higher college attendance rates than Generation X, many Millennials were stuck in low-paid jobs, with the percentage of degree-educated young adults working in low-wage industries rising from 23% to 33% between 2000 and 2014.
Yet despite all the hardship they have had to endure, they still have remained optimistic, as shown when about nine out of ten millennials surveyed by the Pew Research Center said that they currently have enough money or that they will eventually reach their long-term financial goals.
[2] Millennials enjoy a number of important advantages compared to their elders, such as higher levels of education, and longer working lives, but they suffer some disadvantages including limited prospects of economic growth, leading to delayed home ownership.
[115] As they saw their economic prospects improved in the aftermath of the Great Recession, the COVID-19 global pandemic hit, forcing lock-down measures that resulted in an enormous number of people losing their jobs.
[125] Volunteering activities between 2007 and 2008 show the millennial age group experienced almost three-times the increase of the overall population, which is consistent with a survey of 130 college upperclassmen depicting an emphasis on altruism in their upbringing.
[134] Even Millennials who do not have children prefer homes with plenty of space, so that the extra rooms can be turned into an office, a place for their hobbies, or a bedroom for an aging parent.
[153] Historically, high schools separated students on career tracks, but all this changed in the late 1980s and early 1990s thanks to a major effort in the large cities to provide more abstract academic education to everybody.
[159] Quantitative historian Peter Turchin noted that the United States was overproducing university graduates in the 2000s and predicted, using historical trends, that this would be one of the causes of political instability in the 2020s, alongside income inequality, stagnating or declining real wages, growing public debt.
According to Turchin, intensifying competition among graduates, whose numbers were larger than what the economy could absorb, leads to political polarization, social fragmentation, and even violence as many become disgruntled with their dim prospects despite having attained a high level of education.
[169] Over 95% of American millennials were unaware that a portion of the Holocaust occurred in the Baltic states, which lost over 90% of their pre-war Jewish population, and 49% were not able to name a single Nazi concentration camp or ghetto in German-occupied Europe.
Up to 80% of strokes can be prevented by making healthy lifestyle choices while the rest are due to factors beyond a person's control, namely age and genetic defects (such as congenital heart disease).
Besides the common risk factors of heart attacks, namely diabetes, high blood pressure, and family history, young patients also reported marijuana and cocaine intake, but less alcohol consumption.
[197] Surveys conducted in 2018 by the Pew Research Center found that Millennials and Generation Z held similar views on a variety of social and political topics, setting them apart from older cohorts.
[205] In early 2019, Harvard University's Institute of Politics (IOP) Youth Poll asked voters aged 18 to 29—younger millennials and the first wave of Generation Z—what they would like to be priorities for U.S. foreign policy.
[13] As is the case with many European countries, empirical evidence poses real challenges to the popular argument that the surge of nationalism and populism is an ephemeral phenomenon due to 'angry white old men' who would inevitably be replaced by younger and more liberal voters.
[219] In addition, despite the hype surrounding the political engagement and possible record turnout among young voters, millennials' voting power is even weaker than first appeared due to the comparatively higher number of them who are non-citizens (12%, as of 2019), according to William Frey of the Brookings Institution.
[248] Meanwhile, significant number of Millennials and Generation Z is choosing to remain single, because they do not want to be in a relationship, are facing trouble meeting the right people, or have other priorities at present, such as (higher) education or careers.
[252][253] In a 2016 article, Richard Fry of the Pew Research Center described Millennials as "the group much more likely to live with their parents" who were "concentrating more on school, careers and work and less focused on forming new families, spouses or partners and children.
Because Millennial women earn more money, should they choose to stay home when a baby arrives, they risk losing a significant stream of income for their households, at a time when the cost of childcare is increasing rapidly thanks to growing demands.
[267] After the Supreme Court decision Dobbs v. Jackson Women's Health Organization (2022), which returned the right to regulate aspects of abortion not covered by federal law to the individual states, the number of young and childfree adults seeking sterilization went up.
[270] At current trend, Millennials are on track to have the lowest birth rate in history,[271][272][273] surpassing even the cohort that came of age during the First World War, the Spanish flu epidemic, and the Great Depression.
