Too many men? Subnational population imbalances and male childlessness in Finland
Population Studies, 1–21 (2025)
Abstract
Men’s childlessness is increasing in many high-income countries. In Finland, 29 per cent of all men aged 45 were childless in 2022. The cause of these high levels of childlessness is unclear. In this paper, we use rich Finnish population register data to examine whether sex imbalances in regional partner markets are a potential driver of men’s childlessness. Partner markets are imbalanced in a given region if there is a surplus of men relative to women or vice versa. The data generally show an increasingly imbalanced partner market situation for men over time but with considerable regional heterogeneity. Individual-level regression results for men born in 1968–75 (N = 194,080) indicate an increased probability of childlessness at age 45 after extended exposure to imbalanced partner markets over the life course. This association is particularly strong for low-income men. These findings are robust across indicators and specifications. Overall, regional context seems to play a crucial role in the risk of childlessness.
