Social class and fertility: A long-run analysis of Southern Sweden, 1922-2015.

This paper examines social class differences in fertility, using longitudinal micro-level data for a regional sample in Sweden, 1922-2015. Using discrete-time event history models, we estimated the association between social class and parity-specific duration to next birth, adjusting for household income in separate models. Social class was associated with fertility quite independently from income and the association was both parity-dependent and sex-specific. For transitions to parenthood, higher class position was associated with higher fertility for men and lower fertility for women before 1970, but then converged into a positive association for both sexes after 1990. For continued childbearing, a weak U-shaped relationship before 1947 turned into a positive relationship for second births and a negative relationship for higher-order births in the period after 1990. These patterns likely reflect broader changes in work-family compatibility and are connected to profound shifts in labour markets and institutional arrangements in twentieth-century Sweden.
