Data sources

Most of the data on this page comes from the Human Fertility Database (website www.humanfertility.org) (data downloaded February 2014, last updated April 2012). The data collected by the Human Fertility Database is based on government data collection by the Taiwan government. Details about the modalities of data collection are available here.

Warning from HFD: Due to the inconsistency between birth counts and exposure population, the birth data after 1985 should be used with caution. Please see the background and docuemntation file linked above for details.

Data on period fertility

Data on total indicators only without breakdown by birth order

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