How the indicators changed
Fertility (TFR): 7.15 in 1950 → 1.91 in 2023 (−73%). Threshold: below 2.1 since 1998. The trend broke around 1968 and 1981: −0.01 → −0.31 → −0.03 a year.
Births: 0.35k in 1950 → 0.19k in 2023 (−44%). Peak: 0.43k in 1961; the latest value is 55% lower. The trend broke around 1962 and 1979: +0.01k → −0.01k → 0k a year.
Population: 7.47k in 1950 → 17.7k in 2023 (+137%). Peak: 19.8k in 2004; the latest value is 11% lower. The trend broke around 1987 and 2001: +0.17k → +0.39k → −0.11k a year.
Internet: 0% in 1990 → 83.9% in 2024 (+84 pp). Thresholds: above 10% since 2002, above 50% since 2022.
Urban share: 43.9% in 1960 → 79.3% in 2025 (+35 pp). Thresholds: above 50% since 1964, above 75% since 2004. The trend broke around 1969 and 2013: +1.5 → +0.52 → −0.16 a year.
GDP per person (PPP): 17,808 PPP dollars in 1990 → 19,699 PPP dollars in 2025 (+11%). Low: 14,292 PPP dollars in 1993; +38% since then.
GDP growth: on average 0.6% in the 2000s, 1.3% in the 2010s, −4.3% in the 2020s. Lowest: −11.9% in 2021; highest: 8.6% in 2015.
Inflation: on average 2.8% in the 2000s, 2.1% in the 2010s, 5.0% in the 2020s. Lowest: −1.3% in 2016; highest: 13.2% in 2022.
What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1969–1979: 6.58 → 3.49. Over the same years: births 0.42k → 0.29k; population 11.2k → 12.3k; urban share 57.4% → 62.1%; no data for the others in those years.
Over the last 10 years (2013–2023): fertility (TFR) 2.05 → 1.91; births 0.25k → 0.19k; population 17.7k → 17.7k; internet 82.9% (2023); urban share 81.1% → 79.2%; GDP per person (PPP) 17,891 PPP dollars → 16,487 PPP dollars; GDP growth −1.4% → 1.2%; inflation 2.8% → 12.4%.
How the indicators relate
Fertility (TFR) and internet: too few common years with data (6) to speak of a relationship.
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 = 0.64). Changes line up from year to year too, which is more than a shared trend.
Fertility (TFR) and GDP per person (PPP) (1990–2023, 34 years): levels are barely related (r = −0.20); year-to-year changes show no reliable link (r = −0.02).
Forecasts vs actual
Fertility (TFR): past UN projections. The outcome was below the projection in 1 of 1 revisions (2022–2022) and above in none; median gap −19%.
The UN 2022 projection expected today's level (1.91, 2023) only around 2055: reality is 32 years ahead of it.
Fertility (TFR): UN 2024 projection (medium): 2050 — 1.72 (−10% vs 2023), 2100 — 1.69 (−12% vs 2023); low variant for 2100: 1.19.
Births: past UN projections. The outcome was below the projection in 1 of 1 revisions (2022–2022) and above in none; median gap −27%.
The UN 2022 projection expected today's level (0.19k, 2023) only around 2068: reality is 45 years ahead of it.
Births: UN 2024 projection (medium): 2050 — 0.16k (−19% vs 2023), 2100 — 0.11k (−45% vs 2023); low variant for 2100: 0.04k.
Population: past UN projections. The outcome was below the projection in 12 of 12 revisions (1998–2022) and above in none; median gap −23%.
Population: UN 2024 projection (medium): 2050 — 15.5k (−12% vs 2023), 2100 — 11.1k (−37% vs 2023); low variant for 2100: 6.95k.
GDP growth: IMF next-year forecasts (19 editions, 2013–2022). On average the outcome was 6.5 pp below the forecast; below it in 84% of cases; typical error ±8 pp. The biggest miss was for 2021: IMF, April 2020 expected 14.4%, the outcome was −11.9%.
GDP growth: latest IMF forecast (IMF, April 2026): 2024 — 12%, 2026 — 3.3%, 2031 — 2%.
Inflation: IMF next-year forecasts (23 editions, 2013–2024). On average the outcome was 0.6 pp above the forecast; below it in 70% of cases; typical error ±2.9 pp. The biggest miss was for 2022: IMF, April 2021 expected 1%, the outcome was 13.2%.
Inflation: latest IMF forecast (IMF, April 2026): 2026 — 5.9%, 2028 — 2.1%, 2031 — 2.1%.
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.
