Overview

The IDA blend group’s population has grown steadily over the past decade, reflecting the demographic dynamics of its member states. The latest population figure for 2025 stands at 676,957,651, with a one-year growth rate of 1.89%—slightly below the 10-year average annual growth rate of 1.99%. This indicates a marginal deceleration in population expansion, likely due to gradual declines in fertility rates and increasing urbanization in some blend countries, though the overall trend remains robustly positive.
