source notes & method
Values are WPP 2024 figures for 1950 (estimate) and 1 July 2026 (medium-variant projection), as tabulated by StatisticsTimes; a separate WPP-based source (database.earth) gives Niger 15.4 for 2024. Change since 1950 is derived (2026 minus 1950). A 2050 metric was dropped: two secondary sources gave conflicting 2050 values (Niger 21.2 vs 22.1), so it could not be verified. Corrected 3 Nov 2026: title made one idea, 10 words or fewer; no change to the data.
