About this data
The total fertility rate summarizes the total number of births a woman would have, if she experienced the birth rates seen in women of each age group in one particular year across her childbearing years. The wanted fertility is an estimate of what the total fertility rate would be if all unwanted births were avoided, based on survey data.
