Overview
The population of South Asia reached 1,677,384,532 in 2025, reflecting a 1-year growth rate of 0.89%. This moderate annual increase indicates a gradual slowdown in population expansion compared to previous decades, though the region continues to experience significant demographic momentum due to its large base. Over the past ten years, the average annual growth rate has been 0.99%, slightly higher than the 2025 single-year figure, suggesting a long-term trend of decelerating growth as fertility rates decline across many South Asian nations.
