Data on period fertility

Data of total indicators only without breakdown by birth order

Year	CBR (births per 1000 people per year)	CBR minus previous year's CBR	TFR (sum of all age-specific fertility rates), ballpark for replacement fertility is 2.1	TFR minus previous year's TFR	TFR40 (sum of age-specific fertility rates up to the age of 40), almost equal to TFR because births above the age of 40 are rare	TFR40 minus previous year's TFR40

Data on total fertility rate broken down by birth order

The columns TFR1, TFR2, TFR3, and TFR4 describe the total fertility rates at the respective birth orders 1, 2, 3, and 4. The column TFR5+ describes the total fertility rate at higher birth orders (combined). The corresponding "proportion" columns divide the corresponding birth order TFR column by the TFR column (the total across all birth orders). For each row, the proportion columns add up to 1.
