All indicators of the Macroscope base for Saint Martin (French), with sources. Below: what past UN and IMF releases projected and what actually happened.
Computed with the same code as the observations under the main chart and in the API (get_insights). Moving together in time does not prove a cause.

UN projections vs actual
Solid line: actual data, UN WPP 2024 estimates to 2023, then national statistics where comparable with the UN. Dashed: medium variants of past UN revisions. The table shows what each revision expected for the latest year (or five-year period) with actual data.
