What changed at the same time
- The fastest decline of "Fertility (TFR)" was in 1986–1996: 6.01 → 2.54. Over the same years: births 2.09M → 1.12M; population 51.4M → 62.9M; internet 0% (1996); urban share 54.2% → 61.1%; GDP per person (PPP) 11,010 PPP dollars (1996); GDP growth −9.8% → 6.4%; inflation 23.7% → 23.9%.
- Over the last 10 years (2013–2023): fertility (TFR) 1.91 → 1.70; births 1.49M → 1.17M; population 80.4M → 90.6M; internet 30% → 83.7%; urban share 72.3% → 76.7%; GDP per person (PPP) 14,735 PPP dollars → 17,045 PPP dollars; GDP growth −1.5% → 5.3%; inflation 32.9% → 40.7%.
How the indicators relate
- Fertility (TFR) and internet (1990–2023, 31 years): levels are barely related (r = −0.35); year-to-year changes show no reliable link (r = 0.19).
- Fertility (TFR) and urban share (1960–2023, 64 years): levels are strongly related, in opposite directions (r = −0.95); 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.
- Fertility (TFR) and GDP per person (PPP) (1990–2023, 34 years): levels are strongly related, in opposite directions (r = −0.72); year-to-year changes show no reliable link (r = 0.17). This looks like a shared trend: both change over time, but not in step from year to year.
