Profile snapshot from the site dataset regenerated 2026-09-01. Observed years only; IMF projections are excluded.

A dotted value moved sharply against the previous observed value in its series, which is the usual signature of a series break or a source revision; it is a prompt to check, not a judgement. In the last row, ≠ means the profile’s current figure differs from the latest value here by more than 2%: none do on this page.
