What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1989–1999: 6.39 → 2.90. Over the same years: births 9.34k → 5.89k; population 218k → 277k; internet 0% → 1.1%; urban share 25.8% → 27%; GDP per person (PPP) 8,946 PPP dollars → 13,449 PPP dollars; GDP growth 9.3% → 7.2%; inflation 7.2% → 3%.

How the indicators relate
Fertility (TFR) and internet (1990–2023, 34 years): levels are noticeably related, in opposite directions (r = −0.68); year-to-year changes show no reliable link (r = 0.29).
Fertility (TFR) and urban share (1960–2023, 64 years): levels are strongly related, in opposite directions (r = −0.88); year-to-year changes show no reliable link (r = 0.23). 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 = −0.87); 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 10 of 11 revisions (1998–2022) and above in 1; median gap −14%.
The UN 1998 projection did not expect today's level (1.58, 2023) before its horizon ended (2047).

Fertility (TFR): UN 2024 projection (medium): 2050 — 1.54 (−2% vs 2023), 2100 — 1.58 (0% vs 2023); low variant for 2100: 1.08.
Births: past UN projections. The outcome was below the projection in 9 of 11 revisions (1998–2022) and above in 2; median gap −16%.
The UN 2006 projection did not expect today's level (5.8k, 2023) before its horizon ended (2047).
The UN 2022 projection expected today's level (5.8k, 2023) only around 2027: reality is 4 years ahead of it.
Births: UN 2024 projection (medium): 2050 — 5.28k (−9% vs 2023), 2100 — 4.22k (−27% vs 2023); low variant for 2100: 1.74k.
Population: past UN projections. The outcome was below the projection in 3 of 12 revisions (1998–2022) and above in 9; median gap +9%.
The UN 1998 projection expected today's level (526k, 2023) only around 2029: reality is 6 years ahead of it.
The UN 2017 projection expected today's level (526k, 2023) only around 2035: reality is 12 years ahead of it.
Population: UN 2024 projection (medium): 2050 — 590k (+12% vs 2023), 2100 — 475k (−10% vs 2023); low variant for 2100: 326k.
GDP growth: IMF next-year forecasts (34 editions, 2007–2023). On average the outcome was 0.1 pp below the forecast; below it in 35% of cases; typical error ±7 pp. The biggest miss was for 2020: IMF, October 2019 expected 6%, the outcome was −32.9%.
GDP growth: latest IMF forecast (IMF, April 2026): 2025 — 5%, 2027 — 4.6%, 2031 — 4%.

Inflation: latest IMF forecast (IMF, April 2026): 2026 — 3%, 2028 — 2%, 2031 — 2.3%.
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.
