Overview

The IDA & IBRD total population of 6.93 billion in 2025 accounts for roughly 86% of the world’s estimated 8.1 billion people, highlighting the extensive reach of World Bank lending operations. The 1-year growth rate of 0.99% indicates a slight deceleration compared to the 10-year average of 1.11%, suggesting a gradual demographic slowdown across these countries. This trend is consistent with global patterns of declining fertility rates and aging populations, particularly in IBRD-eligible nations like China, India, and Brazil, which have seen reduced population growth over the past decade. Meanwhile, IDA countries—many in Sub-Saharan Africa—continue to experience higher growth rates, though their overall contribution to the aggregate is tempered by smaller population bases.
