- WHO: no figure here after 2021, while others reach 2024
figure no figure here, inside its range no later figure recorded change
Why the numbers differ
- Every source here is a period life table: it applies one year's death rates by age to a newborn for a whole life. It is a summary of that year's mortality, not a forecast of how long a baby born today will live, so a bad year pulls it down at once.
- Sources stop in different years, so a row counts only lines within one year of its newest source. A national population projection never counts and never sets that year, as with OECD's 2025 figures for Colombia, Mexico and Peru. WHO's downloadable file ends in 2021, a pandemic year, so WHO lines are shown with their series but not counted. The UN's estimates end in 2023, so they are not counted where OECD reports 2025: Chile, Costa Rica. (source, retrieved 2026-11-02)
- Where deaths are not fully registered, the figure is modelled from surveys, censuses and child-mortality estimates. In 2021 the median gap between the UN and WHO was 0.39 years in countries WHO lists under vital registration and 1.18 years in those it lists under model life tables. (source, retrieved 2026-11-02)
- Where deaths are well registered the sources sit close together: in 28 of 36 countries with a Eurostat figure for 2023 the UN figure is within half a year of it. Eurostat recalculates from reported deaths, and the UN fits a model to the same registers. (source, retrieved 2026-11-02)
- According to OECD's sources document, as read on 2 November 2026 (the copy is kept with the raw files; scripted requests to the link got HTTP 200 and, in a later check, HTTP 403), methods differ in the detail. Australia, New Zealand and Türkiye use three-year periods, and OECD averages men and women for Japan and the United Kingdom. Eurostat and Statistics Norway treat ages above 90 differently, and Mexico, Colombia and Peru report figures from population projections. (source, retrieved 2026-11-02)
- These lines are not fully independent. WHO uses the UN's population estimates and registered deaths the UN also uses. OECD's sources document, as read on 2 November 2026 (the copy is kept with the raw files; scripted requests to the link got HTTP 200 and, in a later check, HTTP 403), names Eurostat for 28 countries and the World Bank for 8, whose figures match the UN series, and those lines are not counted. For the United Kingdom and Türkiye, Eurostat and OECD rest on the same national registers, so only the newer of the two counts. (source, retrieved 2026-11-02)
Common mistakes
- Life expectancy at birth is not the age most people reach. Deaths in childhood pull the average down, so a low figure does not mean adults there usually die at that age.
- A World Bank or OECD figure is often not a second source. Check whose data it repeats before treating two matching numbers as agreement.
- A UN figure for a recent year in a country with thin registration is an estimate from a model, even when it is printed to several decimals. (source, retrieved 2026-11-02)
