About a quarter (24%) of women who had their first child from 2020 to 2024 lived with an unmarried partner, up from around 17% in the early 1990s, according to a new U.S. Census Bureau report.
But a smaller share of women had their first child while neither married nor living with a partner, dropping from roughly 20% to about 15% in 30 years.
From 2020 to 2024, only about 4% of first-time mothers with a bachelor’s degree or higher were neither married nor living with a partner, and roughly 11% were cohabiting.
During the same time, the estimated share of first-time mothers who were married at the time of birth remained at approximately 60%.
Over the years, it also became more common among women with a bachelor’s degree or higher to be married at first birth, with the share jumping from about 75% in the early 1990s to roughly 85% this decade.
From 2020 to 2024, only about 4% of first-time mothers with a bachelor’s degree or higher were neither married nor living with a partner, and roughly 11% were cohabiting.
The opposite occurred among those with less than a bachelor’s degree: fewer were married at first birth (roughly 40% this decade compared to about 60%) but the share living with a partner rose from about 20% to 35%.
These educational differences highlight a growing divide in family stability: socioeconomically advantaged individuals are increasingly likely – and their less advantaged peers decreasingly likely – to be in stable arrangements such as marriage.
