As of 2025, the population of IDA-only countries — a World Bank aggregate group of low-income nations eligible for concessional lending — stands at 1,269,842,894. This figure reflects a sustained demographic expansion driven by high fertility rates and declining mortality across many of the world’s poorest regions. The group’s population continues to grow at a pace significantly above the global average, highlighting ongoing challenges and opportunities in development.
Overview
IDA-only countries represent some of the most rapidly growing populations in the world. The latest data for 2025 shows a total population of 1.27 billion, with a one-year growth rate of 2.25%. Over the past decade, the average annual growth rate has been 2.26%, indicating consistent demographic pressure. This rate is nearly three times the global average, as many IDA-only nations in Sub-Saharan Africa and parts of South Asia experience high birth rates and declining infant mortality.
