Fertility Trends
In 2016 the U.S. fertility rate hit a record low,1) and remains below replacement level.2) Significant shifts in family formation have coincided with and contributed to changes in fertility trends in the United States. The rise in non-marital sexual intercourse, the contraceptive revolution, and decisions to postpone or altogether avoid marriage have resulted in fewer births per a woman and more childless women.3)
Marital Status
The share of never-married American adults remains at a historic high.4) Young adults are increasingly delaying or even foregoing marriage, frequently opting for cohabitation instead.5) Though births to unmarried women remains high–at 39.7 percent of all births in 20166)–marriage is the most stable and secure environment to have children.7)
Sexual Frequency
Americans had less frequent sexual intercourse in the 2010s than in the 1990s, according to data from the 1989-2014 General Social Survey.8) This overall decline in sexual frequency is largely a result of the decline in marriage, because married people tend to have sexual intercourse more frequently.9)
