What the data shows
Computed with the same code as the observations under the main chart and in the API (get_insights). Moving together in time does not prove a cause.
How the indicators changed
- Fertility (TFR): 3.62 in 1950 → 1.14 in 2025 (−68%). Thresholds: below 2.1 since 1974, below 1.5 since 1992. The trend broke around 1956: change slowed down (−0.21 → −0.02 a year).
- Births: 2.46M in 1950 → 709k in 2024 (−71%). The trend broke around 1957 and 1969: −109k → +23.1k → −21.5k a year.
- Population: 86.4M in 1950 → 124M in 2023 (+44%). The trend broke around 1982 and 2004: +1.05M → +402k → −166k a year.
- Internet: 0% in 1990 → 85.5% in 2024 (+86 pp). Thresholds: above 10% since 1998, above 50% since 2004. Fastest growth in 1999–2004: 21.4% → 62.4%.
- Urban share: 63.3% in 1960 → 92.3% in 2025 (+29 pp). Threshold: above 75% since 1974. The trend broke around 1974 and 1993: +0.86 → +0.11 → +0.56 a year.
- GDP per person (PPP): 36,138 PPP dollars in 1990 → 48,283 PPP dollars in 2025 (+34%).
- GDP growth: on average 4.3% in the 1980s, 1.4% in the 1990s, 0.5% in the 2000s, 1.3% in the 2010s, 0.4% in the 2020s. Lowest: −5.9% in 2009; highest: 6.7% in 1988.
- Inflation: on average 2.5% in the 1980s, 1.2% in the 1990s, −0.2% in the 2000s, 0.5% in the 2010s, 1.9% in the 2020s. Lowest: −1.3% in 2009; highest: 7.8% in 1980.
What changed at the same time
- The fastest decline of "Fertility (TFR)" was in 1950–1960: 3.62 → 1.98. Over the same years: births 2.46M → 1.67M; population 86.4M → 96.4M; urban share 63.3% (1960); no data for the others in those years.
- Over the last 10 years (2015–2025): fertility (TFR) 1.42 → 1.14; births 995k → 709k; population 127M (2015); internet 91.1% → 85.5%; urban share 91.4% → 92.3%; GDP per person (PPP) 44,589 PPP dollars → 48,283 PPP dollars; GDP growth 1.8% → 1.2%; inflation 0.8% → 3.2%.
How the indicators relate
- Fertility (TFR) and internet (1990–2024, 35 years): levels are noticeably related, in opposite directions (r = −0.55); year-to-year changes show no reliable link (r = 0.08).
- Fertility (TFR) and urban share (1960–2025, 66 years): levels are strongly related, in opposite directions (r = −0.81); year-to-year changes show no reliable link (r = 0.09). 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) (1990–2025, 36 years): levels are noticeably related, in opposite directions (r = −0.66); year-to-year changes show no reliable link (r = 0.08).
Forecasts vs actual
- Fertility (TFR): past UN projections. The outcome was below the projection in 12 of 12 revisions (1998–2022) and above in none; median gap −20%.
- Fertility (TFR): UN 2024 projection (medium): 2050 — 1.35 (+18% vs 2025), 2100 — 1.47 (+29% vs 2025); low variant for 2100: 0.97.
- Births: past UN projections. The outcome was below the projection in 9 of 11 revisions (1998–2022) and above in 2; median gap −9.6%.
- The UN 2015 projection did not expect today's level (709k, 2024) before its horizon ended (2097).
- National statistics for 2024: 709k, 6% below the UN 2024 medium variant (751k).
- Births: UN 2024 projection (medium): 2050 — 728k (+3% vs 2024), 2100 — 558k (−21% vs 2024); low variant for 2100: 208k.
- Population: past UN projections. The outcome was below the projection in 4 of 12 revisions (1998–2022) and above in 8; median gap +0.3%.
- The UN 2006 projection expected this level (124M) already around 2020: reality is 3 years behind it.
- The UN 2019 projection expected today's level (124M, 2023) only around 2025: reality is 2 years ahead of it.
- Population: UN 2024 projection (medium): 2050 — 105M (−15% vs 2023), 2100 — 76.8M (−38% vs 2023); low variant for 2100: 53.4M.
- GDP growth: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 0.9 pp below the forecast; below it in 61% of cases; typical error ±1.7 pp. The biggest miss was for 2009: IMF, April 2008 expected 1.5%, the outcome was −5.9%.
- GDP growth: latest IMF forecast (IMF, April 2026): 2026 — 0.7%, 2028 — 0.6%, 2031 — 0.6%.

- Inflation: latest IMF forecast (IMF, April 2026): 2026 — 2.2%, 2028 — 2%, 2031 — 2%.
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.
