Examining the link: educational expansion and non-marital fertility in Croatia

This paper studies the macro-level relationship between education and non-marital fertility in Croatia. Using vital statistics on first births from 1984 to 2021, we explored non-marital fertility trends by mothers’ education and assessed the influence of women’s educational expansion. We observed a significant increase in the proportion of non-marital births, from under 10% in the mid-1980s to over 30% by 2021. Decomposition analysis showed that behavioural changes, particularly among medium-educated women, significantly influenced the increase in non-marital fertility. This group increasingly opted for childbearing outside of marriage. High-educated women also contributed to the trend, with the behavioural changes more modest in comparison to those of medium-educated women, but amplified by an increase in their group size. Direct standardization showed that higher educational attainment among first-time mothers moderated the proportion of non-marital births, suggesting that the proportion of non-marital births could have been even higher had the educational composition remained constant at 1984 levels. The study confirmed a persistent negative educational gradient, where lower educational attainment was associated with a higher likelihood of non-marital childbearing. The results have important implications for policymakers, as discussed in the paper.
