Total Fertility Rate by Country: Comparing Global Birth Patterns
The total fertility rate (TFR), defined as the average number of children a woman would bear over her lifetime based on current age-specific fertility rates, is a key indicator of global birth patterns. Closely tied to birth rates by country, TFR provides insights into population growth, economic development, and societal trends. As of 2025, global fertility rates continue to decline, with significant variations across regions and countries. This article explores the latest TFR data, regional differences, driving factors, and future implications, incorporating birth rates by country, demographic trends, and expert analyses.
Understanding Total Fertility Rate and Birth Rates
TFR measures the average number of live births per woman of reproductive age (typically 15–44), assuming age-specific fertility rates remain constant. Unlike the crude birth rate (live births per 1,000 people), TFR is independent of population age structure, making it ideal for cross-country comparisons. A TFR of 2.1 is considered the replacement level in developed countries, sufficient to maintain population size without migration, though it can be higher (up to 3.5) in countries with elevated mortality rates.
In 2023, the global TFR was approximately 2.3, down from 4.8 in 1950, reflecting a dramatic decline over seven decades. By 2050, projections estimate a global TFR of 1.8, with only a few countries exceeding replacement levels by 2100. These trends signal a shift toward lower birth rates globally, with profound implications for economies, aging populations, and resource allocation.
Regional Variations in Total Fertility Rates
TFR varies widely by region, driven by economic, cultural, and social factors. Sub-Saharan Africa maintains the highest fertility rates, with countries like Niger (6.1) and Chad (5.9) leading in 2023. High TFRs in this region stem from low contraception use, early marriage, and cultural values favoring large families. Despite declines—for instance, Nigeria’s TFR fell from 6.35 in 1960 to 5.3 in 2019—sub-Saharan Africa’s rates remain nearly twice the global average.
In contrast, East Asia and Southern Europe exhibit the lowest TFRs. South Korea’s TFR reached a historic low of 0.7 in 2023, followed by Taiwan (1.11) and Hong Kong (0.74). These “lowest-low” fertility rates (below 1.3) reflect socioeconomic pressures, career prioritization among women, and limited family support policies. Europe’s TFR averages 1.38, with Bulgaria (1.81) and France (1.66) having the highest rates in the region, yet still below replacement.
South Asia shows moderate declines, with India’s TFR dropping to 2.0 by 2019–2021, aligning with replacement levels. Afghanistan’s TFR, once among the highest at 8.0 in the 1990s, fell to 4.5 by 2023, aided by improved education and healthcare access. Latin America and the Caribbean average a TFR of 1.9, with countries like Brazil (1.6) reflecting urbanization and increased contraceptive use.
Factors Driving Fertility Rate Trends
Several factors influence TFR and birth rates by country:
- Economic Development: Wealthier nations with higher education levels and urbanization tend to have lower TFRs, as women prioritize careers and delay childbearing. In contrast, low-income countries have higher TFRs due to reliance on children for labor and limited access to education.
- Contraceptive Access: In sub-Saharan Africa, only 29% of women use modern contraceptives, compared to 65% globally, contributing to higher TFRs. Improved access could lower rates significantly.
- Female Education: Higher education levels correlate with lower fertility. In Niger, achieving universal education by 2030 could reduce TFR from 5.0 to 2.7 by 2050.
- Cultural Norms: Early marriage and large-family preferences persist in some regions, while urban societies increasingly value smaller families.
- Policy Interventions: Pro-natal policies, such as childcare subsidies in France, can modestly boost TFR, while restrictive policies, like Romania’s 1960s contraception bans, historically increased rates but harmed maternal health.
Expert Insights and Recent Studies
A 2025 McKinsey Global Institute report highlights the economic challenges of falling TFRs, noting that 60% of countries already have deaths exceeding births, shifting demographic balances toward aging populations. The report projects that without migration, many economies will face labor shortages by 2050. A 2024 Lancet study by the Institute for Health Metrics and Evaluation (IHME) predicts that by 2100, 97% of countries will have TFRs below 2.1, with only six—Samoa, Somalia, Tonga, Niger, Chad, and Tajikistan—exceeding replacement levels.
Bloomberg’s 2024 demographic analysis emphasizes the shift in global birth distribution, projecting that by 2100, over 75% of births will occur in low-income countries, particularly in sub-Saharan Africa, posing challenges for food security and economic development. Experts like Natalia Bhattacharjee from IHME stress that “accelerating access to education and contraceptives in high-fertility regions could halve TFRs by 2050, aligning with sustainable development goals.”
Implications of Declining Fertility Rates
Low TFRs in developed countries, such as Japan (1.2) and Italy (1.21), contribute to aging populations and shrinking workforces, straining pension systems and healthcare. In 2023, Japan’s working-age population was 59%, down from 70% in 2000, a trend mirrored in South Korea and China. Conversely, high TFRs in low-income countries like Niger strain infrastructure, with rapid population growth overwhelming schools and healthcare systems.
Globally, declining TFRs could lead to a population peak by 2084, estimated at 10.43 billion, followed by gradual decline. This shift may reduce environmental pressures but challenges economic growth in countries with low TFRs. Policymakers face dual challenges: supporting aging populations in low-fertility regions and managing resource demands in high-fertility ones.
Total Fertility Rates in Select Countries (2023)
| Country | Total Fertility Rate (births per woman) | Crude Birth Rate (per 1,000 people) |
|---|---|---|
| Niger | 6.1 | 45.0 |
| Chad | 5.9 | 42.8 |
| India | 2.0 | 16.9 |
| France | 1.66 | 10.9 |
| South Korea | 0.7 | 5.3 |

Conclusion
The total fertility rate by country reveals a world of contrasting birth patterns, from high TFRs in sub-Saharan Africa to historic lows in East Asia and Europe. As global TFR declines toward 1.8 by 2050, nations face unique challenges: high-fertility countries must manage rapid population growth, while low-fertility countries grapple with aging populations and economic strain. Addressing these trends requires targeted policies—enhancing education and contraceptive access in high-fertility regions and supporting families in low-fertility ones. By understanding and acting on these global birth patterns, policymakers can ensure sustainable development and economic stability in an evolving demographic landscape.
