All indicators of the Macroscope base for Sint Maarten (Dutch), 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.
How the indicators changed
Fertility (TFR): 5.26 in 1950 → 1.45 in 2023 (−72%). Thresholds: below 2.1 since 1999, below 1.5 since 2019. The trend broke around 1959 and 1982: −0.05 → −0.11 → −0.02 a year.
Births: 0.06k in 1950 → 0.39k in 2023 (×7). Peak: 0.69k in 1995; the latest value is 43% lower. The trend broke around 1972 and 1992: +0.01k → +0.02k → −0.01k a year.
Population: 1.45k in 1950 → 42.8k in 2023 (×29). The trend broke around 1978 and 1991: +0.33k → +1.48k → +0.37k a year.
Urban share: 100% in 1960 → 100% in 2025 (0 pp).
GDP per person (PPP): 50,981 PPP dollars in 2009 → 48,273 PPP dollars in 2025 (−5%). Peak: 53,786 PPP dollars in 2011; the latest value is 10% lower.
What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1963–1973: 4.47 → 3.11. Over the same years: births 0.1k → 0.21k; population 3.58k → 7.92k; urban share 100% → 100%; no data for the others in those years.
Over the last 10 years (2013–2023): fertility (TFR) 1.89 → 1.45; births 0.49k → 0.39k; population 35.9k → 42.8k; urban share 100% → 100%; GDP per person (PPP) 52,801 PPP dollars → 46,571 PPP dollars.
How the indicators relate
Fertility (TFR) and GDP per person (PPP) (2009–2023, 15 years): levels are strongly related, in the same direction (r = 0.88); year-to-year changes show no reliable link (r = 0.35). This looks like a shared trend: both change over time, but not in step from year to year.
Forecasts vs actual
Fertility (TFR): past UN projections. The outcome was below the projection in 1 of 1 revisions (2022–2022) and above in none; median gap −7.5%.
Fertility (TFR): UN 2024 projection (medium): 2050 — 1.46 (+1% vs 2023), 2100 — 1.53 (+6% vs 2023); low variant for 2100: 1.03.
Births: past UN projections. The outcome was below the projection in 1 of 1 revisions (2022–2022) and above in none; median gap −0.8%.
The UN 2022 projection expected this level (0.39k) already around 2022: reality is 1 year behind it.
Births: UN 2024 projection (medium): 2050 — 0.42k (+7% vs 2023), 2100 — 0.32k (−18% vs 2023); low variant for 2100: 0.12k.
Population: past UN projections. The outcome was below the projection in 5 of 5 revisions (2012–2022) and above in none; median gap −3.3%.
The UN 2015 projection expected this level (42.8k) already around 2022: reality is 1 year behind it.
The UN 2017 projection expected this level (42.8k) already around 2022: reality is 1 year behind it.
Population: UN 2024 projection (medium): 2050 — 51k (+19% vs 2023), 2100 — 42.3k (−1% vs 2023); low variant for 2100: 29.4k.
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.
