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): 6.53 in 1950 → 2.58 in 2023 (−61%). The trend broke around 1978 and 1984: −0.09 → +0.26 → −0.11 a year.
- Births: 204k in 1950 → 362k in 2023 (+77%). Low: 111k in 1977; ×3.3 since then. The trend broke around 1978 and 1991: −1.01k → +11.5k → +0.16k a year.
- Population: 4.38M in 1950 → 17.4M in 2023 (×4). The trend broke around 1989 and 1998: +38.1k → +604k → +217k a year.
- Internet: 0% in 1990 → 68.5% in 2024 (+68 pp). Thresholds: above 10% since 2016, above 50% since 2018. Fastest growth in 2013–2018: 6% → 65%.
- Urban share: 10.2% in 1960 → 41.1% in 2025 (+31 pp). Low: 4.7% in 1975; +36 pp since then. The trend broke around 2008: change sped up (+0.17 → +1.5 a year).
- GDP per person (PPP): 2,646 PPP dollars in 1990 → 7,300 PPP dollars in 2025 (×2.8). Low: 1,595 PPP dollars in 1997; ×4.6 since then. The trend broke around 1996 and 2002: −234 → +87 → +227 a year.
- GDP growth: on average 6.5% in the 1990s, 9.0% in the 2000s, 7.5% in the 2010s, 3.3% in the 2020s. Lowest: −3% in 2020; highest: 14.1% in 2005.
- Inflation: on average 18.5% in the 1980s, 57.5% in the 1990s, 4.8% in the 2000s, 3.1% in the 2010s, 2.8% in the 2020s. Lowest: −31.2% in 1987; highest: 191% in 1991.
What changed at the same time
- The fastest decline of "Fertility (TFR)" was in 1967–1977: 6.20 → 2.72. Over the same years: births 267k → 111k; population 6.33M → 5.67M; urban share 10.5% → 5.6%; no data for the others in those years.
- Over the last 10 years (2013–2023): fertility (TFR) 2.74 → 2.58; births 373k → 362k; population 15.2M → 17.4M; internet 6% → 68.9%; urban share 25.8% → 40.6%; GDP per person (PPP) 4,419 PPP dollars → 6,695 PPP dollars; GDP growth 7.8% → 5%; inflation 2.9% → 2.1%.
How the indicators relate
- Fertility (TFR) and internet (1990–2023, 28 years): levels are noticeably related, in opposite directions (r = −0.51); year-to-year changes show no reliable link (r = 0.08).
- Fertility (TFR) and urban share (1960–2023, 64 years): levels are noticeably related, in opposite directions (r = −0.58); year-to-year changes are weakly related (r = 0.46). Changes line up best with a 5 years shift: "Urban share" moves first, then "Fertility (TFR)" (r = −0.77).
- Fertility (TFR) and GDP per person (PPP) (1990–2023, 34 years): levels are strongly related, in opposite directions (r = −0.70); year-to-year changes show no reliable link (r = 0.13). This looks like a shared trend: both change over time, but not in step from year to year. Changes line up best with a 3 years shift: "GDP per person (PPP)" moves first, then "Fertility (TFR)" (r = 0.62).
Forecasts vs actual
- Fertility (TFR): past UN projections. The outcome was below the projection in 4 of 11 revisions (1998–2022) and above in 7; median gap +1.4%.
- The UN 1998 projection expected this level (2.58) already around 2020: reality is 3 years behind it.
- The UN 2012 projection expected this level (2.58) already around 2022: reality is 1 year behind it.
- Fertility (TFR): UN 2024 projection (medium): 2050 — 2.04 (−21% vs 2023), 2100 — 1.80 (−30% vs 2023); low variant for 2100: 1.30.
- Births: past UN projections. The outcome was below the projection in 6 of 11 revisions (1998–2022) and above in 5; median gap −1.3%.
- The UN 2008 projection expected today's level (362k, 2023) only around 2028: reality is 5 years ahead of it.
- The UN 2012 projection expected this level (362k) already around 2022: reality is 1 year behind it.
- Births: UN 2024 projection (medium): 2050 — 328k (−9% vs 2023), 2100 — 237k (−35% vs 2023); low variant for 2100: 89.7k.
- Population: past UN projections. The outcome was below the projection in 7 of 12 revisions (1998–2022) and above in 5; median gap −0.9%.
- The UN 1998 projection did not expect today's level (17.4M, 2023) before its horizon ended (2030).
- The UN 2022 projection expected today's level (17.4M, 2023) only around 2026: reality is 3 years ahead of it.
- Population: UN 2024 projection (medium): 2050 — 21.9M (+26% vs 2023), 2100 — 22.7M (+31% vs 2023); low variant for 2100: 14.7M.
- GDP growth: IMF next-year forecasts (34 editions, 2007–2023). On average the outcome was 0.2 pp below the forecast; below it in 47% of cases; typical error ±1.8 pp. The biggest miss was for 2020: IMF, October 2019 expected 6.8%, the outcome was −3%.
- GDP growth: latest IMF forecast (IMF, April 2026): 2025 — 5%, 2027 — 4.7%, 2031 — 5.5%.
- Inflation: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 0.3 pp above the forecast; below it in 56% of cases; typical error ±2.6 pp. The biggest miss was for 2008: IMF, April 2007 expected 3.5%, the outcome was 25%.
- Inflation: latest IMF forecast (IMF, April 2026): 2026 — 3%, 2028 — 2.5%, 2031 — 3%.
