Educational boundaries explain strength and variation in global fertility convergence

Area of Science:

• Demography
• Sociology
• Global Development Studies

Background:

• Fertility rates and educational attainment are key demographic indicators.
• Understanding the relationship between education and fertility is crucial for global development and policy.
• Previous research indicates a link between education and declining fertility, but global patterns require updated analysis.

Purpose of the Study:

• To analyze global trends in fertility convergence across varying levels of educational attainment.
• To identify regional differences in fertility convergence, particularly focusing on sub-Saharan Africa.
• To examine the specific impact of different educational stages and completion rates on fertility convergence.

Main Methods:

• Utilized 65 years of demographic data from 146 countries.
• Employed statistical analysis to assess fertility convergence patterns.
• Investigated the influence of educational attainment metrics (level, timing, completion) on fertility trends.

Main Results:

• Demonstrated strong global convergence in fertility rates linked to educational attainment.
• Observed that high-income societies are the primary drivers of global convergence.
• Identified slow or negligible convergence in sub-Saharan Africa, with education levels significantly moderating convergence strength and variation.

Conclusions:

• Educational attainment, particularly tertiary education and successful completion, is a critical factor in global fertility convergence.
• Findings highlight disparities in convergence, with sub-Saharan Africa lagging.
• Policy recommendations emphasize supporting higher education and targeted educational cycle completion to reduce global inequalities.
