The percentage of births to unmarried women in the United States has more than doubled since 1980, reaching 40 percent in 2023. This significant shift in family structure reflects changing societal norms and demographic trends over the past four decades. The rise in births outside of marriage has implications for family dynamics, social support systems, and public policy. Age and ethnicity factors in birth rates While the overall percentage of births to unmarried women has stabilized around 40 percent in recent years, birth rates vary significantly across age groups and ethnicities. Unsurprisingly, in 2023, women between 20 and 34 years old had the highest birth rate at 83 births per 1,000 women, while teenagers aged 15 to 19 had the lowest rate at 8 births per 1,000 women. Additionally, Native Hawaiian and Pacific Islander women had the highest fertility rate among all race/ethnicities in 2022, with approximately 2,237.5 births per 1,000 women, compared to the national average of 1,656.5 births per 1,000 women. Changing household structures The increase in births to unmarried women has contributed to evolving household structures in the United States. In 2023, there were approximately 15.18 million families with a single mother, a significant increase from previous decades. This trend aligns with the overall rise in births outside of marriage and suggests a growing need for support systems and policies that address the unique challenges faced by single-parent households.

Basic Demographic Indicators: Proportion of children born to unmarried mothers by nationality (spaniard/foreign national) of the mother. Annual. National.

The rate of legal abortions in the United States has decreased over the last few decades. In 2022, there were around 19.9 legal abortions per 100 live births, whereas the rate was 34 abortions per 100 live births in the year 1990. Since the overturning of Roe v. Wade by the Supreme Court in 2022, states within the U.S. have the right to severely limit or completely ban abortion if they wish, meaning that access to such procedures varies significantly depending on the state or region. Abortion in the U.S. In 2022, there were over 613,000 legal abortions in the United States. Abortion rates in the U.S. are highest among women aged 25 to 29 years and more common among unmarried women than those who are married. In 2022, there were approximately 38 legal abortions per 100 live births among unmarried women compared to four abortions per 100 live births among women who were married.
Public opinion The issue of abortion has been and remains a divisive topic among the general public and continues to be a relevant political issue. As of May 2023, around 44 percent of the population was estimated to be pro-life, while 52 percent were pro-choice and three percent mixed or neither. However, this distribution has fluctuated over the years, with pro-lifers accounting for a larger percentage than pro-choicers as recently as 2019.

Basic Demographic Indicators: Proportion of birth to unmarried mothers by Province. Annual. Provinces.

In 2023, there were about 15.09 million children living with a single mother in the United States, and about 3.05 million children living with a single father. The number of children living with a single mother is down from its peak in 2012, and the number of children living with a single father is down from its peak in 2005.

Marriage and divorce in the United States

Despite popular opinion in the United States that “half of all marriages end in divorce,” the divorce rate in the U.S. has fallen significantly since 1992. The marriage rate, which has also been decreasing since the 1990s, was still higher than the divorce rate in 2021. Half of all marriages may not end in divorce, but it does seem that fewer people are choosing to get married in the first place.

New family structures

In addition to a falling marriage rate, fewer people in the U.S. have children under the age of 18 living in the house in comparison to 1970. Over the past decade, the share of families with children under 18, whether that be married couples or single parents, has stayed mostly steady, although the number of births in the U.S. has also fallen.

Notes: Relative risk ratios (RRR) from multinomial logit models are reported. Outcome base Both Parents on Birth Certificate (65.3% of all births). Outcomes: “Unm. No Pat” Unmarried, No Paternity Acknowledgement (16.5% of all births); “Pat. Ack.” Paternity Acknowledgement (18.2% of all births). The sample of analysis is the universe of births in Michigan over 1993–2006. Standard errors are robust to heteroskedasticity. “Mother is Other Race” includes unknown. Omitted categories: mother's age 20; mother's education HS; mother's race/ethnicity is white; first parity.Significance levels: *p 0.10 **p 0.05 ***p 0.01.
