Overview

  • U.S. total fertility rate dropped to a record-low 1.6 births per woman in 2024, down about 25% since 2007.
  • Demographers caution that snapshot fertility measures can misrepresent actual childbearing, noting cohort data show women average around two children by age 44.
  • Despite rates below replacement, more births than deaths and ongoing immigration are projected to add over 22 million residents by 2050 and nearly 28 million by 2100.
  • Older-adult labor force participation, which rose to 26.9% for ages 65–74 in 2023 and could reach 30.4% by 2033, may alleviate potential worker shortages.
  • Partisan debates over reversing low fertility have pitted proposals for direct cash child allowances and IVF expansion against calls for extended parental leave and subsidized childcare.
