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): 5.91 in 1950 → 3.84 in 2023 (−35%). Peak: 6.74 in 1985; the latest value is 43% lower. The trend broke around 1973 and 1987: +0.01 → +0.06 → −0.08 a year.
Births: 25k in 1950 → 64.7k in 2023 (×2.6). Low: 22k in 1967; ×2.9 since then. The trend broke around 1973 and 1980: −0.17k → +2.48k → +0.62k a year.
Population: 544k in 1950 → 2.15M in 2023 (×4). The trend broke around 1971 and 2004: +1.44k → +22.2k → +43.1k a year.
Internet: 0% in 1990 → 29.8% in 2024 (+30 pp). Threshold: above 10% since 2016. Fastest growth in 2014–2019: 3.3% → 17.9%.
Urban share: 13.5% in 1960 → 46.7% in 2025 (+33 pp). The trend broke around 1980 and 1991: +0.16 → +1.5 → +0.38 a year.
GDP per person (PPP): 1,968 PPP dollars in 1990 → 2,814 PPP dollars in 2025 (+43%). Low: 1,739 PPP dollars in 1998; +62% since then. The trend broke around 2014: change sped up (+8.5 → +55 a year).
GDP growth: on average 2.2% in the 1980s, 2.8% in the 1990s, 2.9% in the 2000s, 4.1% in the 2010s, 4.4% in the 2020s. Lowest: −22.4% in 1998; highest: 16.8% in 1999.

What changed at the same time

The fastest decline of "Fertility (TFR)" was in 2013–2023: 4.93 → 3.84. Over the same years: births 62.9k → 64.7k; population 1.7M → 2.15M; internet 3.1% → 28.7%; urban share 41.3% → 45.6%; GDP per person (PPP) 2,193 PPP dollars → 2,661 PPP dollars; GDP growth 3.3% → 5.2%; inflation 0.8% → 7.2%.

How the indicators relate

Fertility (TFR) and internet (1990–2023, 28 years): levels are strongly related, in opposite directions (r = −0.89); year-to-year changes show no reliable link (r = −0.29). This looks like a shared trend: both change over time, but not in step from year to year.
Fertility (TFR) and urban share (1960–2023, 64 years): levels are noticeably related, in opposite directions (r = −0.68); year-to-year changes show no reliable link (r = 0.18).
Fertility (TFR) and GDP per person (PPP) (1990–2023, 34 years): levels are strongly related, in opposite directions (r = −0.85); year-to-year changes show no reliable link (r = 0.03). This looks like a shared trend: both change over time, but not in step from year to year.

Forecasts vs actual

Fertility (TFR): past UN projections. The outcome was below the projection in 10 of 11 revisions (1998–2022) and above in 1; median gap −7%.
The UN 1998 projection expected this level (3.84) already around 2019: reality is 4 years behind it.
The UN 2022 projection expected today's level (3.84, 2023) only around 2024: reality is 1 year ahead of it.
Fertility (TFR): UN 2024 projection (medium): 2050 — 2.56 (−33% vs 2023), 2100 — 1.94 (−49% vs 2023); low variant for 2100: 1.44.
Births: past UN projections. The outcome was below the projection in 10 of 11 revisions (1998–2022) and above in 1; median gap −9.6%.
The UN 2010 projection expected this level (64.7k) already around 2019: reality is 4 years behind it.
The UN 2022 projection expected this level (64.7k) already around 2022: reality is 1 year behind it.
Births: UN 2024 projection (medium): 2050 — 71.1k (+10% vs 2023), 2100 — 60.9k (−6% vs 2023); low variant for 2100: 28k.
Population: past UN projections. The outcome was below the projection in 5 of 12 revisions (1998–2022) and above in 7; median gap +0.3%.
The UN 1998 projection did not expect today's level (2.15M, 2023) before its horizon ended (2030).
The UN 2022 projection expected today's level (2.15M, 2023) only around 2024: reality is 1 year ahead of it.
Population: UN 2024 projection (medium): 2050 — 3.44M (+60% vs 2023), 2100 — 4.67M (+117% vs 2023); low variant for 2100: 3.19M.
GDP growth: IMF next-year forecasts (32 editions, 2007–2022). On average the outcome was 0.3 pp below the forecast; below it in 53% of cases; typical error ±2.2 pp. The biggest miss was for 2014: IMF, April 2013 expected 10.2%, the outcome was 1%.
GDP growth: latest IMF forecast (IMF, April 2026): 2024 — 4.8%, 2026 — 4.9%, 2031 — 4.2%.

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.
