Since 2010, fertility has declined sharply, raising the question of whether this recent decline represents an acceleration of longer-term trends—or a new phase in family formation. Who still becomes a parent, and who remains childless? 3/3

Helsinki Institute for Demography and Population Health @pophel.bsky.social · 30/09/2026

Fertility in Finland remained remarkably stable for several decades, but this stability masked substantial changes in who had children and when. Childbearing shifted to older ages, lifetime childlessness increased, and the relationship between education and parenthood changed markedly. 2/3
