What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1985–1995: 6.87 → 5.09. Over the same years: births 1.82k → 1.86k; population 37.8k → 48.3k; internet 0% (1995); urban share 64% → 67.5%; GDP per person (PPP) 4,704 PPP dollars (1995); no data for the others in those years.
Over the last 10 years (2013–2023): fertility (TFR) 3.25 → 2.92; births 1.34k → 0.82k; population 50.7k → 38.8k; internet 14% → 64.1%; urban share 74.7% → 78.4%; GDP per person (PPP) 4,470 PPP dollars → 6,775 PPP dollars; GDP growth 3.8% → −5.3%; inflation 1.9% → 7.4%.
How the indicators relate
Fertility (TFR) and internet (1990–2023, 32 years): levels are strongly related, in opposite directions (r = −0.77); year-to-year changes show no reliable link (r = 0.14). This looks like a shared trend: both change over time, but not in step from year to year.
Fertility (TFR) and urban share (1960–2023, 64 years): levels are strongly related, in opposite directions (r = −0.87); year-to-year changes show no reliable link (r = 0.38). This looks like a shared trend: both change over time, but not in step from year to year.
Fertility (TFR) and GDP per person (PPP) (1990–2023, 34 years): levels are noticeably related, in opposite directions (r = −0.69); year-to-year changes show no reliable link (r = −0.19).
Forecasts vs actual
Fertility (TFR): past UN projections. The outcome was below the projection in 0 of 1 revisions (2022–2022) and above in 1; median gap +11%.
Fertility (TFR): UN 2024 projection (medium): 2050 — 2.11 (−28% vs 2023), 2100 — 1.75 (−40% vs 2023); low variant for 2100: 1.25.
Births: past UN projections. The outcome was below the projection in 0 of 1 revisions (2022–2022) and above in 1; median gap +7.7%.
Births: UN 2024 projection (medium): 2050 — 0.44k (−46% vs 2023), 2100 — 0.26k (−68% vs 2023); low variant for 2100: 0.09k.
Population: past UN projections. The outcome was below the projection in 12 of 12 revisions (1998–2022) and above in none; median gap −39%.
Population: UN 2024 projection (medium): 2050 — 25.2k (−35% vs 2023), 2100 — 23.8k (−39% vs 2023); low variant for 2100: 13.3k.
GDP growth: IMF next-year forecasts (20 editions, 2013–2022). On average the outcome was 0.6 pp below the forecast; below it in 45% of cases; typical error ±3.8 pp. The biggest miss was for 2019: IMF, April 2018 expected 1.7%, the outcome was 10.5%.
GDP growth: latest IMF forecast (IMF, April 2026): 2024 — 3%, 2026 — 3.7%, 2031 — 1.6%.
Inflation: IMF next-year forecasts (20 editions, 2013–2022). On average the outcome was 0.7 pp below the forecast; below it in 70% of cases; typical error ±2 pp. The biggest miss was for 2023: IMF, October 2022 expected 2.2%, the outcome was 7.4%.
Inflation: latest IMF forecast (IMF, April 2026): 2024 — 5.2%, 2026 — 7.4%, 2031 — 2.4%.
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.
