US fertility rate drops to all-time low, continuing a two-decade decline

The United States has recorded its lowest-ever fertility rate, according to data released by the National Center for Health Statistics in Washington, D.C., on April 24, 2024. This milestone continues a persistent two-decade decline, with the rate falling by nearly 23 percent since 2007, a trend driven by complex social, economic, and generational shifts. The decline is not a sudden event but the continuation of a long-term demographic transformation. The total fertility rate, which estimates the average number of children a woman would have in her lifetime, has now fallen below the replacement level of 2.1 for several consecutive years. This means the U.S. population would eventually decline without immigration. The drop since 2007 is particularly steep, indicating an acceleration of factors influencing family planning decisions. Demographers point to a confluence of reasons for this sustained downturn. Key factors include increased educational and career opportunities for women, leading many to delay childbearing; rising economic uncertainty and the high cost of living, especially expenses related to housing and childcare; and changing societal attitudes toward marriage and family size among younger generations, particularly Millennials and Gen Z. This trend mirrors patterns seen in other developed nations but presents unique challenges for long-term economic planning, social security systems, and labor market dynamics in the United States.
