America's child population is shrinking everywhere but the South

America's under-18 population decreased by 1.8 million from 2020 to 2025, with the South being the only region to see growth, adding 303,969 children, while the West experienced the largest decline of 1,015,068. The South's overall population grew 6%, nearly double the national 3.1%, driven by migration and births, impacting political and economic dynamics for Black and Latino families.
