What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1956–1966: 4.03 → 2.28. Over the same years: births 9.47k → 5.48k; population 323k → 326k; urban share 89.4% (1966); no data for the others in those years.
Over the last 10 years (2013–2023): fertility (TFR) 1.37 → 1.10; births 4.07k → 4.21k; population 429k → 533k; internet 68.9% → 92.1%; urban share 94.4% → 95.6%; GDP per person (PPP) 40,921 PPP dollars → 60,460 PPP dollars; GDP growth 6.3% → 10.6%; inflation 1% → 5.6%.
How the indicators relate
Fertility (TFR) and internet (1990–2023, 30 years): levels are strongly related, in opposite directions (r = −0.91); year-to-year changes show no reliable link (r = −0.08). 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 = −0.79); year-to-year changes show no reliable link (r = 0.25). 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 = −0.05). 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 11 of 11 revisions (1998–2022) and above in none; median gap −15%.
Fertility (TFR): UN 2024 projection (medium): 2050 — 1.26 (+14% vs 2023), 2100 — 1.41 (+28% vs 2023); low variant for 2100: 0.91.
Births: past UN projections. The outcome was below the projection in 6 of 11 revisions (1998–2022) and above in 5; median gap −0.3%.
The UN 2000 projection expected today's level (4.21k, 2023) only around 2030: reality is 7 years ahead of it.
The UN 2022 projection expected today's level (4.21k, 2023) only around 2033: reality is 10 years ahead of it.
Births: UN 2024 projection (medium): 2050 — 3.37k (−20% vs 2023), 2100 — 2.24k (−47% vs 2023); low variant for 2100: 0.77k.
Population: past UN projections. The outcome was below the projection in 1 of 12 revisions (1998–2022) and above in 11; median gap +24%.
Population: UN 2024 projection (medium): 2050 — 536k (+1% vs 2023), 2100 — 360k (−32% vs 2023); low variant for 2100: 252k.
GDP growth: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 2.3 pp above the forecast; below it in 33% of cases; typical error ±4.1 pp. The biggest miss was for 2017: IMF, April 2016 expected 3%, the outcome was 13%.
GDP growth: latest IMF forecast (IMF, April 2026): 2026 — 3.7%, 2028 — 4%, 2031 — 4%.
Inflation: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 0.2 pp above the forecast; below it in 56% of cases; typical error ±1 pp. The biggest miss was for 2022: IMF, April 2021 expected 1.4%, the outcome was 6.1%.
Inflation: latest IMF forecast (IMF, April 2026): 2026 — 2.5%, 2028 — 2%, 2031 — 2%.
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.
