IDA & IBRD total: Sex ratio at birth (male births per female births)

Key figures

What the numbers say

In 2024, IDA & IBRD total's sex ratio at birth (male births per female births) fell 0.000797 on 2023 (from 1.06 to 1.05).

Across the 30 yearly changes before that (1994 to 2023), the average change was −0.000568 and a typical year strayed about 0.00138 from that (the standard deviation). This year's change was 0.2 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 0.00217 in 1987 and the biggest yearly fall was 0.005 in 2020. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2015 to 2024 the straight-line trend is downward, about 0.00179 a year. A straight line explains 95% of the movement over 10 observed years.

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

A straight-line projection, tested first

Extending that straight line gives about 1.05 for 2027. We show this only because the same method, fitted on earlier years, predicted 2022 to 2024 better than "no change" would have: its average miss was 0.000676, against 0.00154 for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.
