What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1950–1960: 2.93 → 2.16. Over the same years: births 153k → 124k; population 6.01M → 6.7M; urban share 29.1% (1960); no data for the others in those years.
Over the last 10 years (2013–2023): fertility (TFR) 1.43 → 1.50; births 68.9k → 59.8k; population 7.28M → 6.77M; internet 53.5% → 85.4%; urban share 59.6% → 62.1%; GDP per person (PPP) 18,163 PPP dollars → 25,735 PPP dollars; GDP growth 0.5% → 3.7%; inflation 7.7% → 12.4%.
How the indicators relate
Fertility (TFR) and internet (2004–2023, 20 years): levels are strongly related, in the same direction (r = 0.96); year-to-year changes show no reliable link (r = 0.41). 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 = −0.93); 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 GDP per person (PPP) (1995–2023, 29 years): levels are noticeably related, in the same direction (r = 0.63); year-to-year changes show no reliable link (r = −0.12).
Forecasts vs actual
Fertility (TFR): past UN projections. The outcome was below the projection in 6 of 7 revisions (2006–2022) and above in 1; median gap −7%.
The UN 2012 projection expected today's level (1.50, 2023) only around 2031: reality is 8 years ahead of it.
Fertility (TFR): UN 2024 projection (medium): 2050 — 1.56 (+4% vs 2023), 2100 — 1.60 (+6% vs 2023); low variant for 2100: 1.10.
Births: past UN projections. The outcome was below the projection in 7 of 7 revisions (2006–2022) and above in none; median gap −29%.
The UN 2012 projection expected today's level (59.8k, 2023) only around 2046: reality is 23 years ahead of it.
The UN 2022 projection expected today's level (59.8k, 2023) only around 2028: reality is 5 years ahead of it.
Births: UN 2024 projection (medium): 2050 — 46.1k (−23% vs 2023), 2100 — 27.7k (−54% vs 2023); low variant for 2100: 8.43k.
Population: past UN projections. The outcome was below the projection in 8 of 8 revisions (2006–2022) and above in none; median gap −23%.
The UN 2012 projection expected today's level (6.77M, 2023) only around 2055: reality is 32 years ahead of it.
The UN 2022 projection expected today's level (6.77M, 2023) only around 2032: reality is 9 years ahead of it.
Population: UN 2024 projection (medium): 2050 — 5.53M (−18% vs 2023), 2100 — 3.7M (−45% vs 2023); low variant for 2100: 2.39M.
GDP growth: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 1.3 pp below the forecast; below it in 56% of cases; typical error ±2.2 pp. The biggest miss was for 2009: IMF, April 2008 expected 6%, the outcome was −3.1%.
GDP growth: latest IMF forecast (IMF, April 2026): 2026 — 2.8%, 2028 — 3.5%, 2031 — 3.5%.
Inflation: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 1.2 pp above the forecast; below it in 47% of cases; typical error ±2.7 pp. The biggest miss was for 2022: IMF, April 2021 expected 2.4%, the outcome was 12%.
Inflation: latest IMF forecast (IMF, April 2026): 2026 — 5.2%, 2028 — 3%, 2031 — 3%.
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.
