What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1986–1996: 2.74 → 1.71. Over the same years: births 101k → 56.7k; population 4.31M → 4.39M; internet 0% (1996); urban share 44.3% → 45.1%; GDP per person (PPP) 6,063 PPP dollars (1996); GDP growth −5.9% (1996); inflation 23.5% (1996).
Over the last 10 years (2013–2023): fertility (TFR) 1.62 → 1.73; births 47k → 33k; population 3.41M → 3.07M; internet 37.4% → 76.5%; urban share 39.4% → 43%; GDP per person (PPP) 11,080 PPP dollars → 15,981 PPP dollars; GDP growth 9% → 1.2%; inflation 4.6% → 13.4%.
How the indicators relate
Fertility (TFR) and internet (1990–2023, 31 years): levels are barely related (r = 0.23); year-to-year changes are related too (r = 0.63). 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 noticeably related, in opposite directions (r = −0.51); year-to-year changes show no reliable link (r = 0.33).
Fertility (TFR) and GDP per person (PPP) (1990–2023, 34 years): levels are noticeably related, in the same direction (r = 0.45); year-to-year changes show no reliable link (r = 0.15). Changes line up best with a 8 years shift: "Fertility (TFR)" moves first, then "GDP per person (PPP)" (r = −0.59).
Forecasts vs actual
Fertility (TFR): past UN projections. The outcome was below the projection in 1 of 11 revisions (1998–2022) and above in 10; median gap +27%.
The UN 2000 projection expected today's level (1.73, 2023) only around 2036: reality is 13 years ahead of it.
The UN 2010 projection expected today's level (1.73, 2023) only around 2048: reality is 25 years ahead of it.
Fertility (TFR): UN 2024 projection (medium): 2050 — 1.70 (−2% vs 2023), 2100 — 1.67 (−3% vs 2023); low variant for 2100: 1.17.
Births: past UN projections. The outcome was below the projection in 4 of 11 revisions (1998–2022) and above in 7; median gap +4.2%.
The UN 2000 projection did not expect today's level (33k, 2023) before its horizon ended (2047).
The UN 2019 projection expected today's level (33k, 2023) only around 2029: reality is 6 years ahead of it.
Births: UN 2024 projection (medium): 2050 — 25.6k (−22% vs 2023), 2100 — 12.6k (−62% vs 2023); low variant for 2100: 3.45k.
Population: past UN projections. The outcome was below the projection in 12 of 12 revisions (1998–2022) and above in none; median gap −23%.
The UN 2004 projection did not expect today's level (3.07M, 2023) before its horizon ended (2050).
The UN 2017 projection expected today's level (3.07M, 2023) only around 2059: reality is 36 years ahead of it.
Population: UN 2024 projection (medium): 2050 — 2.35M (−23% vs 2023), 2100 — 1.49M (−51% vs 2023); low variant for 2100: 872k.
GDP growth: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 1.1 pp below the forecast; below it in 50% of cases; typical error ±4.6 pp. The biggest miss was for 2009: IMF, April 2008 expected 8%, the outcome was −6%.
GDP growth: latest IMF forecast (IMF, April 2026): 2026 — 1.9%, 2028 — 3.7%, 2031 — 3.5%.
Inflation: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 1.5 pp above the forecast; below it in 50% of cases; typical error ±3.4 pp. The biggest miss was for 2022: IMF, April 2021 expected 5%, the outcome was 28.7%.
Inflation: latest IMF forecast (IMF, April 2026): 2026 — 6.4%, 2028 — 5%, 2031 — 5%.
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.
