What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1967–1977: 5.57 → 4.28. Over the same years: births 77.6k → 87.8k; population 2.21M → 2.76M; urban share 54.4% → 70.2%; no data for the others in those years.
Over the last 10 years (2013–2023): fertility (TFR) 2.36 → 2.24; births 104k → 93.2k; population 5.74M → 5.77M; internet 70.5% → 81.7%; urban share 88.2% → 90.5%; GDP per person (PPP) 16,396 PPP dollars → 11,330 PPP dollars; GDP growth 3.8% (2013); inflation 4.8% → 221.3%.
How the indicators relate
Fertility (TFR) and internet (1990–2023, 30 years): levels are noticeably related, in opposite directions (r = −0.54); year-to-year changes are related too (r = 0.66). Changes line up from year to year too, which is more than a shared trend.
Fertility (TFR) and urban share (1960–2023, 64 years): levels are strongly related, in opposite directions (r = −0.98); year-to-year changes show no reliable link (r = −0.02). 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 = −0.79); year-to-year changes show no reliable link (r = 0.03). 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 0 of 11 revisions (1998–2022) and above in 11; median gap +24%.
Fertility (TFR): UN 2024 projection (medium): 2050 — 1.90 (−15% vs 2023), 2100 — 1.75 (−22% vs 2023); low variant for 2100: 1.25.
Births: past UN projections. The outcome was below the projection in 0 of 11 revisions (1998–2022) and above in 11; median gap +63%.
The UN 2019 projection expected today's level (93.2k, 2023) only around 2028: reality is 5 years ahead of it.
Births: UN 2024 projection (medium): 2050 — 86.6k (−7% vs 2023), 2100 — 66.1k (−29% vs 2023); low variant for 2100: 25.3k.
Population: past UN projections. The outcome was below the projection in 2 of 12 revisions (1998–2022) and above in 10; median gap +23%.
The UN 1998 projection did not expect today's level (5.77M, 2023) before its horizon ended (2030).
The UN 2019 projection expected today's level (5.77M, 2023) only around 2096: reality is 73 years ahead of it.
Population: UN 2024 projection (medium): 2050 — 7M (+21% vs 2023), 2100 — 7.19M (+25% vs 2023); low variant for 2100: 4.89M.
GDP growth: IMF next-year forecasts (26 editions, 2007–2019). On average the outcome was 2.7 pp below the forecast; below it in 69% of cases; typical error ±5.2 pp. The biggest miss was for 2020: IMF, April 2019 expected 2%, the outcome was −26.8%.
GDP growth: latest IMF forecast (IMF, April 2026): 2022 — 1%, 2025 — 4%.
Inflation: IMF next-year forecasts (26 editions, 2007–2019). On average the outcome was 6.7 pp above the forecast; below it in 42% of cases; typical error ±9.1 pp. The biggest miss was for 2020: IMF, April 2019 expected 2.3%, the outcome was 84.9%.
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.
