Northern Mariana Islands: Population ages 15-64, total

Key figures

What the numbers say

In 2025, Northern Mariana Islands' population ages 15-64, total fell 2% on 2024 (from 30,218 to 29,602).

Across the 30 yearly changes before that (1995 to 2024), the average change was −0.1% and a typical year strayed about 4.6% from that (the standard deviation). This year's change was 0.4 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 18.2% in 1982 and the biggest yearly fall was 4.1% in 1969. 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 676.46 a year. A straight line explains 99% 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 27,906 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 821.45, against 1,644 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.
