Countries by Population Growth Rate 2026

About This Dataset

Countries ranked by annual population growth rate as a percentage in 2026, according to UN World Population Prospects 2024 revision estimates. Sub-Saharan African nations continue to record the world's fastest population growth — Niger's annual growth rate of approximately 3.7% means its population doubles every 19 years, a demographic trajectory that places extraordinary pressure on food systems, education infrastructure, healthcare, and employment creation in one of the world's least developed economies.

Analysis

Niger (3.72), Mali (3.14) and Chad (3.08) take the top three in Annual Population Growth Rate (%) in 2026. Values run from 3.72 at the top to -0.43 at the bottom, a spread of 4.15. First and second are separated by 0.58, so the leader sits inside the field rather than apart from it. The field is close behind: 5 of the 8 sit at half the leader's figure or above (1.86+).
