Urban share: 30.8% in 1960 → 61.5% in 2025 (+31 pp). Threshold: above 50% since 1994. The trend broke around 2010: direction reversed (+0.67 → 0 a year).
GDP per person (PPP): 27,191 PPP dollars in 1990 → 42,577 PPP dollars in 2025 (+57%). The trend broke around 2007 and 2013: +622 → −519 → +660 a year.
GDP growth: on average 3.7% in the 1980s, 3.4% in the 1990s, 1.0% in the 2000s, 0.8% in the 2010s, 1.9% in the 2020s. Lowest: −8.2% in 2020; highest: 7.9% in 1990.
Inflation: on average 16.7% in the 1980s, 5.8% in the 1990s, 2.6% in the 2000s, 1.2% in the 2010s, 3.2% in the 2020s. Lowest: −0.9% in 2009; highest: 29.3% in 1984.
What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1976–1986: 2.81 → 1.66. Over the same years: births 187k → 125k; population 9.31M → 9.99M; urban share 38.7% → 45.2%; GDP growth 3.3% (1986); inflation 11.7% (1986); no data for the others in those years.
Over the last 10 years (2014–2024): fertility (TFR) 1.23 → 1.41; births 82.2k → 84.6k; population 10.4M → 10.4M; internet 64.6% → 88.5%; urban share 61.1% → 61.3%; GDP per person (PPP) 35,097 PPP dollars → 42,228 PPP dollars; GDP growth 0.7% → 2.2%; inflation −0.2% → 2.7%.
How the indicators relate
Fertility (TFR) and internet (1990–2024, 35 years): levels are noticeably related, in opposite directions (r = −0.58); 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 = −0.93); year-to-year changes show no reliable link (r = −0.17). 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) (1990–2024, 35 years): levels are barely related (r = −0.38); year-to-year changes are weakly related (r = 0.41).
Forecasts vs actual
Fertility (TFR): past UN projections. The outcome was below the projection in 6 of 11 revisions (1998–2022) and above in 5; median gap −3.9%.
The UN 2008 projection expected this level (1.41) already around 2014: reality is 10 years behind it.
The UN 2017 projection expected today's level (1.41, 2024) only around 2036: reality is 12 years ahead of it.
Fertility (TFR): UN 2024 projection (medium): 2050 — 1.57 (+12% vs 2024), 2100 — 1.61 (+14% vs 2024); low variant for 2100: 1.11.
Births: past UN projections. The outcome was below the projection in 5 of 12 revisions (1998–2022) and above in 7; median gap +2.5%.
National statistics for 2025: 87.8k, 3% above the UN 2024 medium variant (85.7k).
Births: UN 2024 projection (medium): 2050 — 82.6k (−6% vs 2025), 2100 — 78.4k (−11% vs 2025); low variant for 2100: 34.6k.
Population: past UN projections. The outcome was below the projection in 5 of 12 revisions (1998–2022) and above in 7; median gap +2.5%.
Population: UN 2024 projection (medium): 2050 — 9.77M (−6% vs 2023), 2100 — 8.75M (−16% vs 2023); low variant for 2100: 6.28M.
GDP growth: IMF next-year forecasts (34 editions, 2007–2023). On average the outcome was 0.6 pp below the forecast; below it in 38% of cases; typical error ±1.9 pp. The biggest miss was for 2020: IMF, October 2019 expected 1.6%, the outcome was −8.2%.
GDP growth: latest IMF forecast (IMF, April 2026): 2025 — 1.9%, 2027 — 1.8%, 2031 — 1.6%.
Inflation: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 0.2 pp above the forecast; below it in 56% of cases; typical error ±1.3 pp. The biggest miss was for 2022: IMF, April 2021 expected 1.2%, the outcome was 8.1%.
Inflation: latest IMF forecast (IMF, April 2026): 2026 — 3.1%, 2028 — 2.4%, 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.
