When Careers Compete with Cradles: What Women’s Work Reveals About Fertility Decline in Developing Countries

Fertility rates are falling across much of the developing world, but the reasons behind the decline are more complex than a simple story of women entering the workforce and having fewer children. A new research paper by Thi Kim Ngan Nguyen of Tokyo International University examines whether women's participation in the labor market affects fertility across 115 developing countries between 1991 and 2018. The study found that female labor participation appears to reduce fertility significantly in North and South America, but not in Africa, Asia/Pacific, or developing Europe.

Many developing countries are navigating demographic transition, changing gender roles, rising education levels, urbanization, and pressure to expand decent work opportunities. Falling fertility raises questions about future labor supply, ageing populations, social protection systems, and long-term economic planning.

The issue is not abstract. Even after the period covered by the study, India's official Sample Registration System (SRS) 2024 report shows a Total Fertility Rate of 1.9, below the replacement level of 2.1, with rural fertility at 2.1 and urban fertility at 1.5. It shows that fertility decline continues to be a critical issue for major developing economies, reinforcing the study's broader relevance.

The research suggests that policymakers should avoid assuming that women's employment automatically drives fertility decline everywhere. In many regions, childbearing decisions appear to be shaped more strongly by education, household structures, cultural expectations, political conditions, and economic pressures than by employment alone.

The Americas stand apart

The strongest evidence in the study comes from North and South America, where women's participation in the labor market is associated with lower fertility across the models used, indicating that in these countries, career decisions and reproductive choices may be more directly connected.

The finding points to a familiar policy challenge: when labor markets, childcare systems, parental leave, and workplace norms do not support families, women may face sharper trade-offs between employment and childbearing. In such settings, higher female employment can coincide with delayed motherhood, smaller families, or decisions not to have children.

For governments in Latin America and the Caribbean, the finding strengthens the case for family-supportive labor policies. Affordable childcare, flexible work arrangements, parental leave, anti-discrimination protections, and stronger reproductive health services could help reduce the conflict between paid work and family formation. Businesses also have a role to play by designing workplaces that do not penalize women for motherhood or caregiving responsibilities.

Beyond employment: culture, education, and family structures matter

In Africa, Asia/Pacific, and developing Europe, the study finds no statistically robust evidence that female labor participation alone has a significant effect on fertility. It means employment may not be the dominant driver of fertility decisions once other social, economic, and cultural factors are considered.

India's below-replacement fertility reinforces this point. Its fertility decline reflects a wider development transition involving urbanization, education, health access, delayed marriage, and changing family aspirations. The contrast between rural and urban fertility also shows why national averages can hide important differences within developing countries.

In Africa, the study points to the importance of education, economic conditions, political systems, and broader socioeconomic factors. Fertility behavior in many African countries is shaped by access to schooling, reproductive health services, gender norms, income security, and institutional capacity. Policies focused only on labor participation may therefore miss deeper determinants of reproductive decision-making.

In Asia/Pacific, family structure and cultural norms appear especially important. The study considers factors such as couples living with parents, reflecting the influence of extended family systems and intergenerational household arrangements. In some societies, fertility decisions are shaped not only by women's employment but also by expectations around caregiving, son preference, marriage patterns, and household authority.

In developing Europe, the study finds that female employment does not have a clear effect on fertility once statistical robustness is considered. However, tertiary education may influence the timing of childbirth, reflecting a broader pattern in which higher education can delay family formation. It suggests that education and life-course transitions may matter more than employment status alone.

On the whole, fertility decline in developing countries cannot be explained by a single variable. Women's work matters, but its effects depend on the institutions, norms, and support systems surrounding women's lives.

What policymakers should take from the evidence

The study carries several practical implications for governments, development agencies, businesses, and civil society organizations.

• Policy design must be regional and context-specific. A family policy that responds to work-family conflict in Latin America may not address the main fertility drivers in Africa or Asia. Policymakers should diagnose the actual barriers shaping reproductive choices in each country, rather than importing models from developed economies or other regions.
• Women's employment policies should be integrated with childcare, education, health, and social protection systems. Expanding women's access to work without addressing unpaid care burdens can deepen pressure on women rather than expand their choices. Labor market reforms should be accompanied by investment in early childhood care, maternal health, parental leave, safe transport, and protection against workplace discrimination.
• Development agencies should pay closer attention to family structures and informal labor markets. Many women in developing countries work outside formal employment, making standard labor-force data incomplete. Informal work, unpaid family labor, and home-based enterprise may shape fertility decisions differently from formal wage employment.
• Education policy: Female education changes aspirations, bargaining power, fertility timing, and access to reproductive health information. But the relationship is not always linear. Higher education may delay childbirth, while basic education can improve health knowledge and family planning outcomes. Policymakers need more precise evidence on how different levels of education affect fertility choices across regions.

Additionally, businesses should view this research as part of a wider workforce planning agenda. As more women enter paid work, companies that offer flexible schedules, maternity protections, childcare support, and career continuity may be better positioned to retain skilled workers. In emerging markets, family-friendly employment practices can become a competitive advantage.

The Bigger Picture

The study challenges a common assumption in development debates: that women's employment and fertility decline are automatically linked in the same way everywhere. The evidence suggests a more nuanced reality. In the Americas, work and fertility appear closely connected. In Africa, Asia/Pacific, and developing Europe, other forces may be more influential.

For the Global South, this gap is critical. India's TFR falling to 1.9 makes the issue especially timely: even large developing economies are now entering a phase where fertility decline must be considered alongside jobs, education, social protection, ageing, and regional inequality. If policymakers misunderstand the drivers of fertility decline, they may design ineffective or even counterproductive interventions.

The research also reinforces a broader development lesson: empowerment is not simply about participation in the labor market. It is about expanding real choices. Women should not have to choose between economic opportunity and family life. Nor should fertility policy become a tool for limiting women's autonomy. The goal should be to create conditions in which reproductive decisions are voluntary, informed, healthy, and supported by strong institutions.

It is important to note that the study relies on national-level data, some fertility estimates are interpolated from five-year periods, and informal employment may not be fully captured. Important factors such as childcare access, parental leave, family policies, migration, urbanization, and patrilocal family systems require deeper investigation. Still, its contribution is valuable: it provides broad comparative evidence that fertility decline in developing countries is regionally differentiated and socially embedded.

For future research, the next step is to move from national correlations to household-level evidence. Researchers need to understand how women and families make decisions under real constraints: job insecurity, childcare costs, housing pressures, family expectations, education aspirations, and access to reproductive healthcare.
