Why they rank where they do
-
South KoreaSouth Korea's own count rose to 0.80 in 2025, with 254,300 births. It was the second rise in a row, after a record low of 0.72 in 2023.
-
TaiwanBirths in Taiwan fell by a fifth in one year, from 134,856 in 2024 to 107,812 in 2025, the fewest on record.
-
SingaporeFrom 1972 Singapore's government campaigned for families to "Stop at Two". In 1987 it switched to "Have three or more, if you can afford it". Singapore's own count for 2025 was a record low of 0.87.
-
UkraineIn the territory Ukraine's government controls, births fell from 273,770 in 2021 to 168,780 in 2025, and deaths were 2.9 times births in 2025. About 5.9 million refugees from Ukraine were abroad in February 2026.
-
ChinaChina's one-child policy ran from 1980 to 2015. All couples could have two children from 2016 and three from 2021. Births still fell to 7.92 million in 2025, the fewest since 1949, and China's population fell for the fourth year in a row.
-
JapanJapan recorded 671,236 births in 2025, the 10th record low in a row. Births first fell below 700,000 in 2024, for the first time since records began in 1899.
-
United StatesThe CDC recorded a record low fertility rate of about 1.60 in 2024. The United States keeps growing mainly through immigration.
-
FranceIn 2025 more people died in France than were born, 651,000 against 645,000, for the first time since 1945. France's own fertility rate fell to 1.56, the lowest since the end of World War I.
-
IndiaIndia fell below replacement level in its national health survey of 2019-21. The rate differs widely by state: official data for 2024 put Bihar at 2.9 and Kerala and Tamil Nadu at 1.3.
-
IsraelIsrael has by far the highest fertility rate in the OECD, the club of rich countries: about 2.9 children per woman in Israel's own statistics, against an OECD average of 1.5. Haredi (ultra-Orthodox) Jewish women have about 6.5 children on average.
-
NigerNiger had the world's highest fertility rate for many years. Its 2012 health survey found about 7.6 children per woman.
Which countries have the highest fertility rates?
The eight highest fertility rates are all in sub-Saharan Africa. Chad leads with 5.94 children per woman, just ahead of Somalia and DR Congo. These countries also have some of the youngest populations on Earth: the median age in 2024 was 15.4 in Niger, 15.6 in Mali and 15.7 in Chad.
Outside Africa, Afghanistan has the highest rate, 4.66, followed by Yemen at 4.41. Nigeria, Africa's most populous country, is at 4.30.
What is the replacement fertility rate?
In countries with low death rates, about 2.1 children per woman keeps a population stable without migration. The number is above 2 because about 105 boys are born for every 100 girls, and because some girls die before they reach or finish their childbearing years. Where more children die young, the replacement level is higher.
In 1975, only 24 countries were below 2.1. In 2025, 104 of the 196 countries in this ranking are below it, and about 67% of the world's people live in them. The UN projects that the world's population will peak at about 10.3 billion in 2084.
Which countries' fertility rates have fallen the most?
Among countries with at least 20 million people, South Korea's fertility rate fell the most between 1975 and 2025, by 77%. Thailand, Iran, China and Taiwan each fell by more than 70%. Every one of the 196 countries in this ranking has a lower rate than in 1975.
Iran's fall was one of the fastest ever recorded. Iranian women had about 6.5 children in the mid-1980s. In December 1989 the government relaunched family planning, and the rate fell to about 2 by 2000. Then Iran's leaders changed course. In 2012 the government cut free contraception. In 2014 Supreme Leader Ali Khamenei made raising births official policy, and a 2021 law restricted contraception, sterilization and abortion.
Can governments raise birth rates?
Some have tried, with little lasting success. South Korea's government spent about 380 trillion won from 2006 to 2023 on policies to raise births. South Korea's rate has risen two years in a row since 2023, but it is still one of the lowest in the world.
In Hungary, under Viktor Orbán, the rate rose from 1.23 in 2011 to 1.61 in 2021, then fell to 1.31 in 2025. Since 2020, Hungarian mothers of four or more children pay no income tax for life, and the exemption is being extended to mothers of three and two. In Georgia, the head of the Georgian Orthodox Church, Patriarch Ilia II, promised in 2007 to personally baptize every third and later child of married Orthodox parents. Births rose from about 49,000 in 2007 to about 63,000 in 2009. Georgia's rate peaked at 2.30 in 2014 and fell to 1.61 in 2025.
