Details about the modalities of data collection are available here. Where available, we use HFD data because of its higher reliability.

Total indicators only without breakdown by birth order

Total indicators with year-on-year differences (change measured additively)

Year Crude birth rate (CBR) (births per 1000 people) CBR minus previous year's CBR Total fertility rate (TFR) (sum of all age-specific fertility rates) ballpark for replacement fertility is 2.1 TFR minus previous year's TFR TFR40 TFR40 minus previous year's TFR40
