Slovenia: Population ages 0-14, total

Key figures

What the numbers say

In 2025, Slovenia's population ages 0-14, total fell 1.4% on 2024 (from 313,045 to 308,615).

Across the 30 yearly changes before that (1995 to 2024), the average change was −0.6% and a typical year strayed about 1.6% from that (the standard deviation). This year's change was 0.5 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 1.5% in 2009 and the biggest yearly fall was 3.2% in 1997. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2016 to 2025 there is no clear straight-line trend: a straight line explains 6% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.
