Naturalisations

Naturalisation here means every grant of citizenship a country records in the year: by application, by marriage, to children with their parents, and by declaration. Births to citizens are not included.

EU and EFTA countries: Eurostat, acquisition of citizenship by previous citizenship (migr_acq), from 2008 to the newest year each country has reported. Germany 2025: Destatis, Pressemitteilung Nr. 186 vom 3. Juni 2026 (vorläufige Ergebnisse). Destatis and Eurostat differ slightly for the same year (2024: 292,000 vs 288,670), so the chart keeps each year's source and never mixes them inside one year.

United Kingdom: UK Home Office, Immigration System Statistics: grants of British citizenship (Cit_D02), complete calendar years from 2005 (Eurostat for 1998–2004). United States: U.S. DHS Office of Homeland Security Statistics, Yearbook of Immigration Statistics 2024, Tables 21–22 (fiscal years, rounded to tens); the breakdown is by country of birth, 2015–2024. Canada: Immigration, Refugees and Citizenship Canada, new citizens by country of birth (open data; 2023 on rounded to 5), by country of birth; 2012–2016 come from an archived IRCC table marked preliminary, and IRCC has not kept 2017–2022 online, so those years are a gap rather than an estimate.

Australia: Australian Department of Home Affairs, citizenship statistics (conferrals by former nationality, financial years; archived editions). Each year is a July–June financial year, plotted at the year it ends (2024–25 at 2025). The page shows only the newest year, so earlier years come from archived editions; 2023–24 was never archived and is a gap. Japan: Ministry of Justice of Japan, 帰化許可申請者数等の推移 (naturalisation permits) and 国籍別帰化許可者数, permits every year since 1967, split into Korea (South or North), China and all others, with the top ten nationalities for the last three years.

Russia: Ministry of Internal Affairs of Russia (MVD), migration statistics, 2017–2025 (Eurostat has 2005). Previous citizenship comes from the ministry's country tables for 2017–2021; for later years it published totals only, several of them rounded to the nearest hundred. The ministry explains the fall in 2024 partly by the recognition of residents of the annexed Ukrainian regions as citizens under constitutional law, so earlier years include large numbers of Ukrainians given passports under simplified rules.

Per 1,000 residents divides new citizens by the World Bank's population for the same year. World Bank population starts in 1960, so rates do too; switch to People to see U.S. naturalisations back to 1907. Retrieved 2026-10-29. Build script: scripts/build-naturalisations.py.
