Post-COVID Migration Fuels Red State Baby Boom

U.S. Census data from 2019 to 2024 shows red states increased children under 18 by 600,000. Trump-voting states started at 43.1 million kids and reached 43.7 million. Blue states, voting for Harris, lost populations in their 20s and children under 10. Idaho, South Carolina, Florida, and Tennessee gained 10% more married families with kids under five. Lower housing costs pulled young families from high-cost blue metros like New York and California.

Timeline of the Family Exodus

2019 baseline marked 43.1 million kids under 18 in red states. 2020-2022 lockdowns enabled remote work relocations, accelerating millennial families in their 30s to affordable areas. By 2024, red states hit 43.7 million children, while blue states shed young families. Late 2025 into early 2026, Institute for Family Studies linked these shifts to election demographics, forecasting Electoral College gains for red states by 2030. Housing deregulation sustains this momentum.

Pre-COVID, red states led birth rates. Post-2020 echoes 2010s Sun Belt moves but targets family formation. Married couples birthed post-2019 babies in Chattanooga, Tennessee, and Florida beaches, transforming retiree spots into family hubs.

Impacts Reshape America

Short-term, red states build electoral power toward 2030 projections; blue states forfeit middle-class tax bases.
