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): 5.11 in 1950 → 2.13 in 2023 (−58%). Peak: 5.59 in 1965; the latest value is 62% lower. The trend broke around 1969 and 1994: +0.03 → −0.12 → −0.02 a year.

GDP per person (PPP): 4,873 PPP dollars in 1990 → 15,091 PPP dollars in 2025 (×3.1). The trend broke around 1996 and 2002: +286 → −92 → +378 a year.

What changed at the same time

The fastest decline of "Fertility (TFR)" was in 1976–1986: 4.92 → 3.53. Over the same years: births 4.84M → 4.79M; population 135M → 170M; urban share 19.5% → 26.9%; GDP growth 7.2% (1986); inflation 5.8% (1986); no data for the others in those years.
Over the last 10 years (2013–2023): fertility (TFR) 2.44 → 2.13; births 5.03M → 4.48M; population 256M → 281M; internet 14.9% → 69.2%; urban share 51.8% → 58.1%; GDP per person (PPP) 10,122 PPP dollars → 13,890 PPP dollars; GDP growth 5.6% → 5%; inflation 6.4% → 3.7%.

How the indicators relate

Fertility (TFR) and internet (1990–2023, 31 years): levels are strongly related, in opposite directions (r = −0.76); year-to-year changes show no reliable link (r = −0.19). 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 strongly related, in opposite directions (r = −0.94); year-to-year changes show no reliable link (r = −0.47). 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) (1990–2023, 34 years): levels are strongly related, in opposite directions (r = −0.83); 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.

Population: past UN projections. The outcome was below the projection in 1 of 12 revisions (1998–2022) and above in 11; median gap +4.6%.
The UN 1998 projection expected today's level (281M, 2023) only around 2029: reality is 6 years ahead of it.
The UN 2022 projection expected today's level (281M, 2023) only around 2025: reality is 2 years ahead of it.
Population: UN 2024 projection (medium): 2050 — 321M (+14% vs 2023), 2100 — 296M (+5% vs 2023); low variant for 2100: 195M.
GDP growth: IMF next-year forecasts (36 editions, 2007–2024). On average the outcome was 0.7 pp below the forecast; below it in 78% of cases; typical error ±1.1 pp. The biggest miss was for 2020: IMF, April 2019 expected 5.2%, the outcome was −2.1%.
GDP growth: latest IMF forecast (IMF, April 2026): 2026 — 5%, 2028 — 5.2%, 2031 — 5.2%.
