Brazil Births Plunge 5.8% in 2024: Why Teen and Young Women’s Fertility Is Dropping

Brazil's births fell 5.8% in 2024 — the steepest decline in over 30 years. Learn why teenage and young women's fertility dropped and what it means for Brazil.

Brazil experienced a sharp fall in births in 2024, with a 5.8% drop—the steepest decline in more than 30 years and the sixth consecutive annual fall. This pronounced birth rate drop has drawn attention from demographers, policymakers, and the public as young women and teenagers are having far fewer children than in previous years.

The decline is especially striking among teenagers and younger women. Teenage pregnancy rates have fallen in many regions, helping drive the overall reduction in births. Changes in behavior, greater access to contraception and reproductive health services, and rising education and employment opportunities for young women are commonly cited factors. These shifts are part of a broader fertility decline that is reshaping Brazil’s population trends.

Several converging causes likely explain the fertility decline. Economic uncertainty and the rising cost of living encourage many couples to delay or limit childbearing. Urbanization and changing social norms, including prioritizing education and careers, also play a role. Improved access to family planning and sexual education reduces unintended pregnancies, particularly among teenagers. While the data show the scale of the decline, researchers emphasize that regional differences and socioeconomic conditions influence how pronounced these trends are across the country.

The demographic implications of a sustained birth rate drop are significant. An ongoing decrease in births contributes to population aging and may slow future workforce growth, with potential effects on economic productivity, public pensions, healthcare demand, and long-term social planning. Governments and local authorities will need to consider how population shifts interact with labor markets, education systems, and social safety nets.

Policy responses can vary: some countries respond to falling fertility with incentives for families—such as childcare support, parental leave, and housing assistance—while others focus on immigration or adapting social programs to an older population. For Brazil, a balanced approach that supports family choices, improves access to affordable childcare, and maintains reproductive health services could help manage demographic change without undermining gains in education and gender equality.

As Brazil continues to track births and fertility indicators, the 2024 drop highlights an important turning point in the country’s population trends. Understanding the causes and consequences will be essential for policymakers, communities, and families navigating Brazil’s demographic future.
