How the indicators changed
Fertility (TFR): 6.52 in 1950 → 3.71 in 2023 (−43%). The trend broke around 1987: direction reversed (0 → −0.09 a year).
Births: 36.2k in 1950 → 99.1k in 2023 (×2.7). The trend broke around 1986 and 2010: +1.27k → +0.71k → −0.08k a year.
Population: 815k in 1950 → 3.47M in 2023 (×4.3). The trend broke around 1998 and 2009: +29.8k → +69.7k → +36.8k a year.
Internet: 0% in 1990 → 14.3% in 2020 (+14 pp). Threshold: above 10% since 2019. Fastest growth in 2015–2020: 1.1% → 14.3%.
Urban share: 10.4% in 1960 → 34.5% in 2025 (+24 pp). The trend broke around 1988 and 2000: +0.18 → +1.6 → 0 a year.
GDP growth: on average 7.9% in the 1990s, −0.6% in the 2000s, 5.3% in the 2010s. Lowest: −20.6% in 2015; highest: 30.9% in 2014.
Inflation: on average 8.8% in the 1990s, 18.5% in the 2000s, 3.3% in the 2010s. Lowest: −14.4% in 2018; highest: 33.9% in 2009.
What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1995–2005: 5.94 → 4.93. Over the same years: births 79.9k → 96.8k; population 2.03M → 2.66M; internet 0% (1995); urban share 27.2% → 35.1%; GDP growth 2.3% → 2.6%; inflation 12% → 12.5%.
Over the last 10 years (2013–2023): fertility (TFR) 4.34 → 3.71; births 97.5k → 99.1k; population 3.07M → 3.47M; internet 0.9% (2013); urban share 35.7% → 34.7%; GDP growth −10.5% (2013); inflation 6.3% (2013).
How the indicators relate
Fertility (TFR) and internet (1990–2020, 25 years): levels are noticeably related, in opposite directions (r = −0.55); year-to-year changes show no reliable link (r = 0.05).
Fertility (TFR) and urban share (1960–2023, 64 years): levels are strongly related, in opposite directions (r = −0.92); year-to-year changes are related too (r = −0.68). Changes line up from year to year too, which is more than a shared trend.
Forecasts vs actual
Fertility (TFR): past UN projections. The outcome was below the projection in 1 of 11 revisions (1998–2022) and above in 9; median gap +1.4%.
The UN 1998 projection expected this level (3.71) already around 2015: reality is 8 years behind it.
The UN 2019 projection expected today's level (3.71, 2023) only around 2024: reality is 1 year ahead of it.
Fertility (TFR): UN 2024 projection (medium): 2050 — 2.60 (−30% vs 2023), 2100 — 1.95 (−47% vs 2023); low variant for 2100: 1.45.
Births: past UN projections. The outcome was below the projection in 11 of 11 revisions (1998–2022) and above in none; median gap −51%.
Births: UN 2024 projection (medium): 2050 — 117k (+18% vs 2023), 2100 — 105k (+6% vs 2023); low variant for 2100: 47.4k.
Population: past UN projections. The outcome was below the projection in 12 of 12 revisions (1998–2022) and above in none; median gap −50%.
The UN 1998 projection expected this level (3.47M) already around 1997: reality is 26 years behind it.
Population: UN 2024 projection (medium): 2050 — 5.7M (+64% vs 2023), 2100 — 8.44M (+143% vs 2023); low variant for 2100: 5.82M.
GDP growth: IMF next-year forecasts (24 editions, 2007–2018). On average the outcome was 0.8 pp above the forecast; below it in 42% of cases; typical error ±13.3 pp. The biggest miss was for 2014: IMF, October 2013 expected 1.9%, the outcome was 30.9%.
Inflation: IMF next-year forecasts (24 editions, 2007–2018). On average the outcome was 5.1 pp below the forecast; below it in 79% of cases; typical error ±11.8 pp. The biggest miss was for 2018: IMF, April 2017 expected 9%, the outcome was −14.4%.
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.
