What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1991–2001: 5.45 → 3.19. Over the same years: births 22.6k → 14.6k; population 600k → 611k; internet 0% → 0.9%; urban share 21% → 28.3%; GDP per person (PPP) 3,338 PPP dollars → 5,546 PPP dollars; GDP growth 4.9% → 7%; inflation 10.3% → 3.7%.
Over the last 10 years (2013–2023): fertility (TFR) 2.00 → 1.46; births 12.4k → 9.96k; population 725k → 786k; internet 22.4% → 90%; urban share 35.6% → 41.7%; GDP per person (PPP) 11,212 PPP dollars → 14,610 PPP dollars; GDP growth 3.4% → 4.9%; inflation 8.1% → 4.5%.
How the indicators relate
Fertility (TFR) and internet (1990–2023, 26 years): levels are strongly related, in opposite directions (r = −0.73); year-to-year changes are weakly related (r = −0.44).
Fertility (TFR) and urban share (1960–2023, 64 years): levels are strongly related, in opposite directions (r = −0.96); year-to-year changes show no reliable link (r = −0.21). 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 strongly related, in opposite directions (r = −0.92); year-to-year changes show no reliable link (r = −0.27). 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 10 of 11 revisions (1998–2022) and above in 1; median gap −23%.
The UN 1998 projection did not expect today's level (1.46, 2023) before its horizon ended (2047).
The UN 2017 projection did not expect today's level (1.46, 2023) before its horizon ended (2097).
Fertility (TFR): UN 2024 projection (medium): 2050 — 1.46 (0% vs 2023), 2100 — 1.53 (+5% vs 2023); low variant for 2100: 1.03.
Births: past UN projections. The outcome was below the projection in 10 of 11 revisions (1998–2022) and above in 1; median gap −29%.
The UN 2006 projection did not expect today's level (9.96k, 2023) before its horizon ended (2047).
The UN 2017 projection expected today's level (9.96k, 2023) only around 2062: reality is 39 years ahead of it.
Births: UN 2024 projection (medium): 2050 — 7.71k (−23% vs 2023), 2100 — 5.46k (−45% vs 2023); low variant for 2100: 1.84k.
Population: past UN projections. The outcome was below the projection in 12 of 12 revisions (1998–2022) and above in none; median gap −7.5%.
The UN 2006 projection expected this level (786k) already around 2020: reality is 3 years behind it.
The UN 2022 projection expected this level (786k) already around 2022: reality is 1 year behind it.
Population: UN 2024 projection (medium): 2050 — 882k (+12% vs 2023), 2100 — 690k (−12% vs 2023); low variant for 2100: 450k.
GDP growth: IMF next-year forecasts (32 editions, 2007–2022). On average the outcome was 1.9 pp below the forecast; below it in 66% of cases; typical error ±3.4 pp. The biggest miss was for 2013: IMF, October 2012 expected 13.5%, the outcome was 3.4%.
GDP growth: latest IMF forecast (IMF, April 2026): 2024 — 6.1%, 2026 — 7.5%, 2031 — 5.6%.
Inflation: IMF next-year forecasts (34 editions, 2007–2023). On average the outcome was 0.4 pp above the forecast; below it in 50% of cases; typical error ±1.8 pp. The biggest miss was for 2012: IMF, September 2011 expected 5%, the outcome was 10.1%.
Inflation: latest IMF forecast (IMF, April 2026): 2025 — 2.6%, 2027 — 4.3%, 2031 — 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.
