CDC / NCHS Demographic Analysis

US Teen Birth & Fertility Trends Explorer

Analyzing the 78.2% drop in US teen birth rates (1991–2024), maternal age shifts, and the dual framing between public health triumph and national demographic replacement anxiety.

Counterfactual Demographic Modeling: "What if Teen Births Never Dropped?"
Toggle simulation to project national annual births if 15–19 birth rates had remained frozen at the 1991 peak (61.8 / 1,000) versus the actual observed rate of 13.5 / 1,000.

Media & Policy Discourse Matrix
Public Health & Mobility Frame Consensus Triumph
Focuses on individual autonomy, reduced child poverty, and maternal education.
  • 78.2% reduction: Achieved through more effective long-acting reversible contraception (LARCs) and evidence-based education.
  • High School Completion: Teen mother graduation rates rose from ~50% in the 1990s to over 75% today.
  • Intergenerational Poverty: Drastic reduction in children born into extreme economic vulnerability.
Demographic Replacement Frame Structural Panic
Focuses on macro population sustainability, workforce size, and entitlement solvency.
  • Sub-replacement TFR: US TFR stands at 1.62, significantly below the 2.1 rate needed to avoid long-term population decline without immigration.
  • Delayed, not just avoided: While some births shifted into 30–34, overall lifetime completed fertility fell.
  • Pensions & Healthcare: Fewer future workers entering the pipeline to support aging baby boomers.
