Slovenia
Based on the most recent published official birth records (and Birthgap harmonisation where noted).
Slovenia's 2023 demographic indicators reveal a continuing decline in completed fertility alongside a notable increase in childlessness. While the average maternal age remains stable near 30 years, the gap between actual fertility and replacement level has slightly widened, reflecting ongoing shifts in family formation patterns.
- Completed fertility dropped by 2.7 percentage points to 72.1%, continuing a downward trend over recent years.
- The lifetime childlessness rate rose by 2.7 percentage points to 27.9%, indicating more individuals are having no children.
- Average maternal age at childbirth shows minimal change, holding steady around 29.7 years.
- The total fertility gap increased marginally to 27.4%, signaling fertility remains below replacement levels in Slovenia.
In 2023, Slovenia's fertility rates and family sizes remain stable but with a continuing rise in childlessness and fertility gaps.
- Children per mother steady at just over 2
- Completed fertility decreased slightly, now just over 70%
- Average maternal age stable near 30 years
- Childlessness rising above 25%
- Societal half-life declined by about 10 years

Motherhood prevalence (TMR)
Among mothers in Slovenia, completed fertility is 72.1% (2023). It is lower than in 2022 (down 2.7pp). Over the past five years, TMR has been falling; the 2019–2023 average is 75.0%. Relative to the earliest available baseline in the 2020s (75.0%), today’s TMR is lower by about 2.9pp. Globally ranking is not available because the country is outside the current rankable comparison set.
