The world's suicide rate fell 14 percent from 2010 to 2021. In 62 economies, it rose.

The suicide-rate figures in this piece are WHO modeled estimates, not direct death counts — the series (World Bank code SH.STA.SUIC.P5, SDG indicator 3.4.2) derives rates from cause-of-death surveillance and statistical modeling; the economy counts and percentage changes are calculations derived from those rates, computed from the unrounded WHO estimates while the rates shown here are rounded to one decimal. SDG 3.4, adopted by all 193 UN member states in 2015, sets a one-third reduction in premature noncommunicable disease mortality by 2030; SDG indicator 3.4.2 is the designated mental-health gauge under that goal, though it carries no numerical reduction target of its own — the one-third mark is used here only as a comparison yardstick. Lithuania's modeled rate was 37.5 per 100,000 in 2010, the highest of the 185 economies with comparable data through 2021, and fell to 22.1 by 2021 — a drop of 41 percent. ^mmodeled Mexico's was 4.5 and rose to 7.0 (up 55 percent). Thailand's was 8.9 and rose to 16.6, up 86 percent — the largest increase among economies with populations over one million. ^mmodeled The world's modeled aggregate fell from 10.67 to 9.13 per 100,000, a decline of 14.4 percent. ^mmodeled Of the 185 economies with comparable 2010 and 2021 estimates — excluding Antigua and Barbuda, whose modeled 2010 rate of zero registers an artifactual rise — 23 cut their modeled rate by one-third or more from the 2010 baseline, 62 recorded a higher rate in 2021 than in 2010, and 100 improved by less than a third. ^mmodeled Europe and Central Asia accounts for the largest regional share of the improvement: 11 of the 23 economies that cleared the one-third mark are in the region. Belarus fell from 34.2 to 15.6 (−54 percent); Kazakhstan from 28.1 to 14.6 (−48 percent); Russia from 35.8 to 21.4 (−40 percent). ^mmodeled Sub-Saharan Africa moved the other way: 30 of 48 economies with data recorded higher modeled rates in 2021 than in 2010. ^mmodeled In Latin America and the Caribbean, 11 of 31 economies worsened, including Brazil (5.3 to 7.6, up 45 percent) and Uruguay (16.1 to 24.8, up 54 percent). ^mmodeled Twelve high-income economies saw rates rise: the United States from 13.2 to 15.6 (up 18 percent), the United Kingdom from 7.8 to 9.6 (up 22 percent), and Spain from 7.0 to 8.7 (up 24 percent) among them. ^mmodeled

The following is analysis, not fact. The steepest percentage declines were concentrated in former-Soviet economies that began 2010 at two to four times the world average — Belarus, Kazakhstan, Lithuania, Russia ^mmodeled. But because a global rate is population-weighted, steep drops in relatively small populations weigh less on the world total than more modest declines across the largest populations. India's modeled rate fell from 15.9 to 12.6 per 100,000; because it carries a population near 1.4 billion, a decline of that size exerts substantially more weight on the global aggregate than comparable movements in Belarus or Lithuania ^mmodeled. A cross-country pattern emerges across two axes. One is regional: Europe and Central Asia improved in 41 of 48 economies, 11 by a third or more; Sub-Saharan Africa did not, with 30 of 48 worse ^mmodeled. The other is starting point: economies that began far above the world average tended to fall; those that began below it tended to rise. Whether those axes are independent — whether the former Soviet-successor states improved because of something the region specifically did — the data alone cannot establish. ^sspeculative South Korea, which recorded 34.9 per 100,000 in 2010, cut to 27.5 by 2021 (−21 percent), tracking the right direction but short of the one-third pace used here as a yardstick. ^mmodeled The hardest finding to explain by resources alone is the high-income cluster. The United States, the United Kingdom, Spain, Norway, and the Netherlands each had established mental health systems in 2010. Each saw its modeled rate rise. The data records that divergence; it does not identify a cause. ^sspeculative PAHO, in its own analysis, has identified the Americas as the only WHO region where aggregate suicide mortality rose over the period it examined — consistent with the country-level pattern this data shows.

These are modeled estimates built on civil registration systems that vary sharply in completeness. In sub-Saharan Africa especially, where many countries have low registration coverage, modeled rates can respond as much to updated data assumptions as to genuine changes in incidence ^sspeculative. The dramatic drops in Belarus and Russia may partly reflect reclassification of deaths previously coded to other causes rather than prevention progress alone ^sspeculative.

**View from Latin America** PAHO has identified the Americas as the only WHO region where aggregate suicide mortality rose over the period of its analysis. At the country level, the picture is more fractured: Chile fell 34 percent, Mexico rose 55, Bolivia fell 27, Uruguay rose 54. What reads from outside as a regional trend maps internally as a set of divergences without a common cause health authorities can easily name. ^sspeculative
