Since 1990, teen births in the U.S. have dropped dramatically—by 73%, with the teen birth rate falling 78%. Experts credit better sex education, contraception access, and Gen Z’s tendency to delay major life changes.
Meanwhile, births among women 40+ have surged: a 127% rise for those aged 40–44 and a 450% jump for those 45+, driven by changing life priorities and assisted reproductive technology.
Today, women over 30 account for over half of all U.S. births, reflecting both greater autonomy and systemic challenges.
Delayed motherhood often stems from lack of paid leave, affordable childcare, and flexible work policies.
While the shift signals more control for women, it also highlights the need for better support for moms of all ages.
