Fertility rates in the United States have been steadily declining since 1957, reducing by more than half. This trend has significant implications for the country’s demographic structure, workforce sustainability, and care for an aging population. While reproductive rights advocates may view this as progress, economists warn that a robust birth rate is essential to maintain economic vitality and support older generations.
The U.S. mirrors a challenge faced by countries like Japan, where low fertility rates have created demographic imbalances. In 2015, North America had approximately four working-age individuals for every older person, while Japan had only two. By 2050, Japan’s population is projected to shrink by 15%, driven by declining birth rates and aging. The burden on younger generations to sustain economic growth and social support systems grows heavier as these trends persist.
Globally, governments have attempted to counteract declining fertility with varied success. Singapore, for instance, introduced “pronatalist incentives” such as cash rewards for families with multiple children, extended parental leave, and housing priority for parents. Despite these measures, the fertility rate fell further, from 1.41 in 2001 to 1.16 in 2018. Public policy scholar Poh Lin Tan attributes this trend to Singapore’s highly competitive social and economic environment, which rewards ambition and penalizes perceived underachievement.
Similarly, in South Korea, societal pressures to provide children with costly supplemental education have deterred many from having larger families. Richard Jackson, president of the Aging Institute, notes that these economic burdens discourage family expansion.
In the U.S., identifying the root causes of declining fertility rates remains complex. The Biden administration’s American Families Plan includes measures that may bolster fertility, but similar policies have had limited success in reversing demographic trends. Research has found no consistent link between fertility declines and factors like religion, student debt, or rent prices.
Notably, while historically women with higher education had fewer children, a 2015 study by the World Economic Forum revealed that U.S. women with advanced degrees now have higher fertility rates than those with less education, likely due to financial stability and career flexibility.
Other contributing factors include rising urbanization, higher housing costs, and increased contraceptive access, particularly through the Affordable Care Act. Teen pregnancy rates, for instance, have plummeted by 78% since 1991. However, the impact of recent abortion restrictions on fertility trends is yet to be fully understood.
Immigration has been a significant driver of U.S. population growth, contributing to 80% of the increase in 2022. However, fewer young immigrant women are entering the country. Policies during the Trump administration saw more immigrants leaving than arriving. While President Biden’s proposal to legalize undocumented residents could create a more welcoming environment, it lacks sufficient congressional support.
Even so, the fertility boost from immigration may be short-lived. Research shows that second-generation immigrants adopt lower fertility rates as they gain access to education and career opportunities.
America’s fertility crisis is a multifaceted challenge requiring nuanced solutions. Whether through policy, social support, or immigration reform, addressing this issue will be essential to maintaining the nation’s economic resilience and social stability in the decades ahead.
