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): 4.99 in 1950 → 1.78 in 2023 (−64%). Threshold: below 2.1 since 1996. The trend broke around 1968 and 1995: +0.01 → −0.06 → −0.01 a year.
Births: 452k in 1950 → 342k in 2023 (−24%). Peak: 549k in 1967; the latest value is 38% lower. The trend broke around 1970 and 1976: +12.5k → −21.4k → −1.42k a year.
Population: 11.1M in 1950 → 26.4M in 2023 (+138%). Low: 10.2M in 1953; ×2.6 since then. The trend broke around 1956 and 1996: −2.75k → +315k → +126k a year.
Internet: 0% in 1990 → 0% in 2004 (0 pp).
Urban share: 40.6% in 1960 → 64.2% in 2025 (+24 pp). Threshold: above 50% since 1967. The trend broke around 1971: change slowed down (+1.4 → +0.12 a year).
What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1950–1960: 4.99 → 3.57. Over the same years: births 452k → 409k; population 11.1M → 11.7M; urban share 40.6% (1960); no data for the others in those years.
Over the last 10 years (2013–2023): fertility (TFR) 1.88 → 1.78; births 338k → 342k; population 25.3M → 26.4M; urban share 60.9% → 63.5%; no data for the others in those years.
How the indicators relate
Fertility (TFR) and internet: too few common years with data (9) to speak of a relationship.
Fertility (TFR) and urban share (1960–2023, 64 years): levels are strongly related, in opposite directions (r = −0.81); year-to-year changes show no reliable link (r = 0.23). 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 11 of 11 revisions (1998–2022) and above in none; median gap −2.8%.
Fertility (TFR): UN 2024 projection (medium): 2050 — 1.67 (−6% vs 2023), 2100 — 1.64 (−8% vs 2023); low variant for 2100: 1.14.
Births: past UN projections. The outcome was below the projection in 6 of 11 revisions (1998–2022) and above in 5; median gap −1.4%.
The UN 1998 projection did not expect today's level (342k, 2023) before its horizon ended (2047).
The UN 2019 projection expected today's level (342k, 2023) only around 2027: reality is 4 years ahead of it.
Births: UN 2024 projection (medium): 2050 — 264k (−23% vs 2023), 2100 — 158k (−54% vs 2023); low variant for 2100: 52.4k.
Population: past UN projections. The outcome was below the projection in 1 of 12 revisions (1998–2022) and above in 11; median gap +2.1%.
Population: UN 2024 projection (medium): 2050 — 25.8M (−2% vs 2023), 2100 — 19.5M (−26% vs 2023); low variant for 2100: 12.7M.
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.
