Fertility Dynamics and Economic Growth
Summary
Fertility dynamics and economic growth are mutually reinforcing processes that shape demographic structures, human capital formation and income trajectories across societies. As economies develop, improvements in health and living standards typically trigger a demographic transition characterised by falling mortality followed by declining fertility. This transition facilitates investments in education and skills, shifting household strategies from raising many low-investment children to fewer high-investment children. The resulting human capital accumulation drives productivity gains, accelerates technological adoption and sustains income growth. Conversely, rising incomes and changing labour market returns alter fertility preferences, creating feedback loops that influence population ageing, labour supply and public finances. Institutional factors—such as pension systems, child allowances and access to family planning—interact with social norms to modulate these dynamics. Regional divergences in the timing and pace of fertility decline highlight the role of policy design, gender equity and economic structure in steering demographic and economic outcomes. A nuanced understanding of these linkages is essential for anticipating labour market shifts, ensuring intergenerational equity and designing policies that balance population ageing with sustainable growth.

Fertility Dynamics and Economic Growth publication trend
The graph below shows the total number of articles in fertility dynamics and economic growth across all publications each year (not limited to Nature Index journals).
Technical terms
Demographic transition: The shift from high to low birth and death rates as societies industrialise and incomes rise.
Fertility rate: The average number of live births per woman over her reproductive lifetime.
Human capital: The skills, education and health that individuals accumulate, enhancing their productivity.
Endogenous fertility model: An economic framework in which fertility decisions are determined within the model by household preferences and constraints.
Quantity–quality trade-off: The choice households make between having more children (quantity) and investing more resources per child (quality).
