What percent of the world is over 40 years old? An analysis of global demographics

Based on 2020 data, approximately 36.8% of the world's population was over 40 years old, a figure that continues to grow. The increasing share of the global population over this age threshold is a key indicator of widespread demographic shifts, largely driven by declining fertility rates and rising life expectancies across the globe. This trend has profound implications for societies, economies, and healthcare systems worldwide.
