But that wisdom was wrong: The meaning of family is morphing once again. Fueled by a convergence of historical currents—including birth control and the rising status of women, increased wealth and social security, LGBTQ activism, and the spread of personal communication technologies and social media—more people are choosing to live alone than ever before.
Pick a random American household today, and it’s more likely to look like Dan’s than like Ozzie and Harriet’s. Nearly half of adults ages 18 and older are single. About 1 in 7 live alone. Americans are marrying later, divorcing in larger numbers, and becoming less interested in remarrying. According to the Pew Research Center, by the time today’s young adults reach age 50, a quarter of them will have never married at all.
The surge of singlehood is not just an American phenomenon. Between 1980 and 2011, the number of one-person households worldwide more than doubled, from about 118 million to 277 million, and will rise to 334 million by 2020, according to Euromonitor International. More than a dozen countries, including Japan and several European nations, now have even larger proportions of solo-dwellers than the U.S. (Sweden ranks highest at almost 50 percent.)2 Individuals, not couples or clans or other social groups, are fast becoming the fundamental units of society.

More than a century of statistical scrutiny tells us that any link between singlehood and asocial behavior, including suicide, has been vastly overstated, if one exists at all.3 And yet the stereotype persists. In our own research on the perceptions of single people, my colleagues and I presented study participants with pairs of near-identical biographical profiles, differing only in marital status. Participants routinely judged the married people as kinder, more loyal, and more caring. They tended to view the singles as shyer, lonelier, and more selfish. [...]
It’s not just singles who are leading the charge. Even traditionally coupled people are living more independently than they once did. A study comparing marriages in 2000 with those in 1980 found that millennial spouses were less likely to eat together, do chores together, go out for fun together, and have as many mutual friends as did spouses 20 years earlier.12 Today’s couples often have separate phones, computers, and online accounts. Although their social networks may overlap, they are unique.
