The global adolescent birth rate has fallen by nearly half since 1994, from 74 births per 1,000 girls and young women aged 15 to 19 to 38 per 1,000 in 2024, according to United Nations World Fertility 2024. That decline ranks among the more significant, and less widely reported, public health successes of the past three decades. It has not, however, been shared evenly.
More than two-thirds of the world’s adolescent births in 2024 still occurred in countries that remain far from completing the broader fertility transition, and the WHO African Region’s adolescent birth rate of roughly 97 per 1,000 as of 2023 remained more than seven times higher than the European Region’s 13.1 per 1,000.
What Counts as an Adolescent Birth?
Demographers track two distinct adolescent age bands separately because the health risks and social implications differ substantially between them: 15 to 19 and 10 to 14. The adolescent birth rate is calculated as the number of live births to women in an age group per 1,000 women of that age, distinct from the adolescent pregnancy rate, which also counts pregnancies that do not end in a live birth. WHO notes that, based on 2019 data, 55 percent of unintended pregnancies among girls aged 15 to 19 ended in abortion, often unsafe in lower-income settings, meaning the birth rate alone understates the true scale of adolescent pregnancy.
How Many Teenage Births Occur Worldwide?
UN World Fertility 2024 puts the global adolescent birth rate for the 15-to-19 age group at 38 per 1,000 in 2024, down from 74 in 1994. For the 10-to-14 age group, the rate fell from 4 to below 1.5 per 1,000 over roughly the same period, per WHO 2023 estimates. UNICEF’s compiled 2023 data placed the global rate for 15-to-19-year-olds at about 39 per 1,000 and the 10-to-14 rate at about 1 per 1,000, figures broadly consistent with the UN’s own estimate given normal cross-source variation in reference year and methodology. Globally in 2023, UNICEF estimated that 13 percent of adolescent girls and young women give birth before age 18.
Global Adolescent Birth Rate Over Time
| Age Group | 1994 | 2023-2024 | Change |
|---|---|---|---|
| 15-19 years | 74 per 1,000 | 38 per 1,000 | -49% |
| 10-14 years | 4 per 1,000 | ~1 to 1.5 per 1,000 | roughly -65 to -75% |

A longer historical view from World Bank-sourced compilations shows an even steeper long-run decline: the global adolescent birth rate for 15-to-19-year-olds fell from 92.1 per 1,000 in 1960 to 38.3 in 2024, a decline of nearly 60 percent across six and a half decades, with virtually all of that decline concentrated in the period since the 1990s.
Where Teenage Births Remain Most Common
Regional disparities are the central fact of this topic. Sub-Saharan Africa and Latin America and the Caribbean continue to record the highest regional adolescent birth rates globally, at 97.9 and 51.4 births per 1,000 women aged 15 to 19, respectively, as of 2023 WHO data. The WHO African Region specifically recorded approximately 97 births per 1,000 adolescents in 2023, compared with just 13.1 per 1,000 in the WHO European Region, a gap of more than seven to one.
Adolescent Birth Rate by Region, Ages 15-19 (2023)
| Region | Adolescent Birth Rate (per 1,000) |
|---|---|
| WHO African Region / Sub-Saharan Africa | ~97.0-97.9 |
| Latin America and the Caribbean | 51.4 |
| Global average | ~38-39 |
| WHO European Region | 13.1 |

Rates of decline have also been uneven by region. Our World in Data’s analysis of UN-compiled figures notes that Central and South Asia recorded the sharpest declines of any region, with rates falling by over three-quarters since 2000, while declines in Latin America and the Caribbean and in Sub-Saharan Africa have been considerably slower.
UNICEF’s own regional comparison confirms the same pattern: South Asia reduced its adolescent birth rate for 10-to-14-year-olds by more than 90 percent, and Latin America and the Caribbean by close to 50 percent, over a comparable measurement period, alongside similarly large reductions for 15-to-19-year-olds.
Teenage Births by Age
Even within a single country, adolescent birth patterns can vary enormously by subnational region and by the precise age band examined. WHO’s fact sheet cites Zambian survey data showing that the share of girls aged 15 to 19 who had begun childbearing, meaning they had already given birth or were pregnant at the time of the survey, ranged from 14.9 percent in Lusaka to 42.5 percent in Southern Province in 2018, a nearly threefold gap within one country.
Births among girls aged 10 to 14 remain far rarer than among 15-to-19-year-olds everywhere, but they carry disproportionately higher health risks and are concentrated even more heavily in Sub-Saharan Africa, where WHO estimated the 2023 rate at 4.4 per 1,000, compared with 2.3 per 1,000 in Latin America and the Caribbean and close to zero in Western Europe, wider Europe and Central Asia, and North America.
Why Adolescent Birth Rates Differ
No single explanation accounts for the wide gap between regions, but several factors are consistently associated with higher adolescent birth rates in the research literature:
- Early marriage. In countries where child marriage remains common, adolescent childbearing often follows directly from adolescent marriage, particularly across parts of Sub-Saharan Africa and South Asia.
- Limited education access. Girls who remain in school longer generally marry and begin childbearing later, and adolescent pregnancy itself frequently interrupts education, creating a cycle that reinforces low educational attainment.
- Contraceptive access. Limited availability of modern contraception in some low-income settings restricts adolescents’ ability to delay or space pregnancies even when they wish to.
- Poverty. Economic hardship is associated with both earlier marriage and earlier childbearing in numerous country-level studies, particularly where marriage or childbearing carries economic significance for a family.
- Healthcare access. Limited access to reproductive healthcare services, including family planning counseling, constrains adolescents’ ability to prevent unintended pregnancy.
- Social and gender norms. In some societies, cultural expectations around early marriage and motherhood for girls remain strong despite legal minimum-age protections.
How Teenage Birth Rates Have Changed
The historical trajectory documented across multiple sources tells a consistent story of substantial, if uneven, global progress. UN World Fertility 2024 data show that among countries and areas still furthest from completing the fertility transition, those where fertility is expected to remain above 2.1 until at least 2054, the adolescent birth rate for 15-to-19-year-olds fell from 118 per 1,000 in 1994 to 79 per 1,000 in 2024, and the 10-to-14 rate fell from 8 to 2 per 1,000 over the same period. Even in the highest-fertility countries, adolescent childbearing has fallen substantially, though it remains well above the global average.
Health, Education and Economic Consequences
WHO documents specific, well-established health risks associated with adolescent childbearing: mothers aged 10 to 19 face higher risks of eclampsia, puerperal endometritis and systemic infections than women aged 20 to 24, and infants born to adolescent mothers face elevated risks of low birth weight, preterm birth and severe neonatal complications.
UNICEF’s analysis adds that early pregnancy frequently disrupts girls’ education, since many are pressured or forced to leave school, with lasting effects on employment and income prospects, and can carry social consequences including stigmatization, reduced status within the household and, in some settings, rejection or violence from family members or partners.
What Happens Next?
UN World Fertility 2024 explicitly recommends raising the average age of marriage and of first childbirth in countries where both occur early as a policy pathway to further reduce adolescent childbearing, alongside continued expansion of access to reproductive healthcare and education.
Given the pace of decline already achieved, particularly the more than 90 percent reduction recorded in South Asia for the youngest adolescent age group, continued global decline appears likely, though the persistent and much slower pace of change in Sub-Saharan Africa means the regional gap in adolescent childbearing is likely to remain wide for years to come even as the global average keeps falling.
Frequently Asked Questions
1. Which country has the highest teenage birth rate?
Individual country rankings shift year to year, but Sub-Saharan African countries consistently dominate the highest end of the range, with the WHO African Region’s overall adolescent birth rate at approximately 97 to 98 per 1,000 as of 2023, far above any other WHO region.
2. Is teenage pregnancy declining worldwide?
Yes, substantially. The global adolescent birth rate for 15-to-19-year-olds fell from 74 per 1,000 in 1994 to 38 in 2024, and from 92.1 per 1,000 in 1960 on a longer view, according to UN and World Bank-sourced data.
3. Why are teenage birth rates higher in some regions?
A combination of early marriage practices, limited education access, restricted contraceptive availability, poverty and, in some settings, strong social expectations around early motherhood contribute to persistently higher adolescent birth rates in parts of Sub-Saharan Africa, South Asia and Latin America.
4. What is the difference between adolescent pregnancy and adolescent birth rate?
Adolescent birth rate measures live births per 1,000 girls in a given age group. Adolescent pregnancy rate is broader and includes pregnancies that end in miscarriage or abortion as well as live birth, meaning it captures more of the true scale of early pregnancy than birth rate alone.
5. How common are births among girls aged 10 to 14?
Much rarer than among 15-to-19-year-olds, at roughly 1 to 1.5 per 1,000 globally as of the mid-2020s, though rates run notably higher in Sub-Saharan Africa, at approximately 4.4 per 1,000, and Latin America and the Caribbean, at about 2.3 per 1,000, than in Europe and North America.
6. What percentage of girls give birth before age 18?
An estimated 13 percent of adolescent girls and young women worldwide gave birth before age 18 as of 2023, according to UNICEF, though this global figure conceals very large regional and national variation.
7. Which regions have seen the fastest declines in teenage birth rates?
Central and South Asia recorded the sharpest declines of any region, with rates falling by more than three-quarters since 2000, and South Asia specifically cut its 10-to-14 adolescent birth rate by more than 90 percent, faster than any other major region tracked.
8. What health risks are associated with teenage pregnancy?
Adolescent mothers face elevated risks of eclampsia, puerperal endometritis and systemic infections compared with women in their early twenties, while their infants face higher risks of low birth weight, preterm birth and severe neonatal complications.
9. Does teenage pregnancy affect education?
Yes, significantly in many settings. Many adolescent girls who become pregnant are pressured or forced to leave school, which can have lasting negative effects on their educational attainment and future employment prospects.
10. What is driving the global decline in teenage births?
Improved access to education, expanded contraceptive availability, delayed marriage age in many countries, and targeted reproductive health policy have all contributed to the sustained, multi-decade decline documented in UN and WHO data, though progress has been markedly slower in Sub-Saharan Africa than elsewhere.
