Oklahoma Has Fifth-Largest Under-18 Population in U.S.—Impacts Schools and Workforce

OKLAHOMA CITY — Oklahoma ranks fifth in the nation for total population under age 18, with over 23% of its residents falling into this demographic category. According to the U.S. Census Bureau’s 2025 estimates, this equates to nearly 900,000 young Oklahomans as of July.

Why This Matters Now

The expanding youth population is creating immediate and long-term implications for the state’s infrastructure—especially in areas such as public education, childcare availability, and recreational services. In high-growth counties like Oklahoma (metro) and Tulsa, schools are reporting larger class sizes and stretched resources.

“We’re seeing unprecedented enrollment increases across elementary and middle schools,”said Carter County’s Superintendent.“That puts pressure on hiring, budgets, and even bus routes.”

A Future Workforce in the Making

Beyond the strain on current services, the high youth population presents an opportunity: a robust future talent pool to support industries like aerospace, energy, and healthcare. Workforce development agencies are already planning initiatives to invest in this generation’s potential.

What’s Next for Policymakers

State lawmakers are examining proposals to invest in pre-K availability and school construction bonds, and to expand childcare subsidies in rural and underserved areas. Demographers also recommend that local governments incorporate youth metrics when planning for roads, parks, and digital infrastructure.
