What the numbers say
In 2025, Iran, Islamic Rep.'s population, male (% of total population) fell 0.02 percentage points on 2024 (from 50.82% to 50.8%).
Across the 30 yearly changes before that (1995 to 2024), the average change was −0 percentage points and a typical year strayed about 0.06 percentage points 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 0.16 percentage points in 2005 and the biggest yearly fall was 0.11 percentage points in 1987. 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 the straight-line trend is downward, about 0.02 percentage points a year. A straight line explains 99% of the movement over 10 observed years.

A straight-line projection, tested first
Extending that straight line gives about 50.76% for 2028. We show this only because the same method, fitted on earlier years, predicted 2023 to 2025 better than "no change" would have: its average miss was 0.03%, against 0.04% 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.
