What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1979–1989: 2.36 → 1.49. Over the same years: births 153k → 109k; population 9.53M → 10.2M; internet 0% (1990); urban share 69.1% → 71.3%; GDP per person (PPP) 26,916 PPP dollars (1990); GDP growth 0.7% → 3.8%; inflation 24.9% → 13.7%.

How the indicators relate
Fertility (TFR) and internet (1990–2024, 35 years): levels are barely related (r = −0.31); year-to-year changes show no reliable link (r = −0.07).
Fertility (TFR) and urban share (1960–2024, 65 years): levels are strongly related, in opposite directions (r = −0.83); year-to-year changes are related too (r = 0.51). Changes line up from year to year too, which is more than a shared trend.
Fertility (TFR) and GDP per person (PPP) (1990–2024, 35 years): levels are barely related (r = 0.06); year-to-year changes show no reliable link (r = 0.16).

Fertility (TFR): UN 2024 projection (medium): 2050 — 1.41 (+14% vs 2024), 2100 — 1.50 (+21% vs 2024); low variant for 2100: 1.00.
Births: past UN projections. The outcome was below the projection in 11 of 12 revisions (1998–2022) and above in 1; median gap −11%.
National statistics for 2025: 65.4k, 4% below the UN 2024 medium variant (68.2k).
Births: UN 2024 projection (medium): 2050 — 67.2k (+3% vs 2025), 2100 — 44k (−33% vs 2025); low variant for 2100: 16.2k.
Population: past UN projections. The outcome was below the projection in 10 of 12 revisions (1998–2022) and above in 2; median gap −5.9%.
Population: UN 2024 projection (medium): 2050 — 8.81M (−14% vs 2023), 2100 — 6.28M (−39% vs 2023); low variant for 2100: 4.35M.
GDP growth: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 2.4 pp below the forecast; below it in 61% of cases; typical error ±3.2 pp. The biggest miss was for 2020: IMF, October 2019 expected 2.2%, the outcome was −9.2%.
GDP growth: latest IMF forecast (IMF, April 2026): 2026 — 1.8%, 2028 — 1.6%, 2031 — 1.6%.
Inflation: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 0.5 pp above the forecast; below it in 47% of cases; typical error ±1.5 pp. The biggest miss was for 2022: IMF, October 2021 expected 0.4%, the outcome was 9.3%.
Inflation: latest IMF forecast (IMF, April 2026): 2026 — 3.5%, 2028 — 2.5%, 2031 — 2.1%.
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.
