As more U.S. adults are delaying marriage – or forgoing it altogether – the share who have ever lived with an unmarried partner has been on the rise.
Young adults are particularly accepting of cohabitation – 78% of those ages 18 to 29 say it’s acceptable for an unmarried couple to live together, even if they don’t plan to get married – but majorities across age groups share this view. Still, even among those younger than 30, a substantial share (45%) say society is better off if couples who want to stay together long-term eventually get married. Roughly half of those ages 30 to 49 say the same, as do majorities of those ages 50 and older.
Views about marriage and cohabitation are also linked to religious affiliation. About three-quarters of Catholics (74%) and white Protestants who do not self-identify as born-again or evangelical (76%) say it’s acceptable for an unmarried couple to live together even if they don’t plan to get married. By contrast, only 47% of black Protestants and 35% of white evangelical Protestants share this view. And while half or more across these groups say society is better off if couples who want to stay together long-term eventually get married, white evangelicals are the most likely to say this (78% do so). Among those who are not religiously affiliated, fully nine-in-ten say cohabitation is acceptable even if a couple doesn’t plan to get married, and just 31% say society is better off if couples who want to stay together eventually get married.
