Excel Tables - Fertility Data

Topic Data File Description
Summary indices Births Number of births over a given period. Refers to five-year periods running from 1 July to 30 June of the initial and final years. Data are presented in thousands.
Summary indices Sex Ratio at Birth (SRB) Number of male births per one female birth.
Summary indices Crude Birth Rate (CBR) Number of births over a given period divided by the person-years lived by the population over that period. It is expressed as average annual number of births per 1,000 population.
Summary indices Total fertility (TFR) The average number of children a hypothetical cohort of women would have at the end of their reproductive period if they were subject during their whole lives to the fertility rates of a given period and if they were not subject to mortality. It is expressed as children per woman.
Summary indices Net Reproduction Rate (NRR) The average number of daughters a hypothetical cohort of women would have at the end of their reproductive period if they were subject during their whole lives to the fertility rates and the mortality rates of a given period. It is expressed as number of daughters per woman.
Age composition Births by Age of Mother Number of births over a given period classified by age group of mother (15-19, 20-24, 25-29, 30-34..45-49). Refers to five-year periods running from 1 July to 30 June of the initial and final years. Data are presented in thousands.
Age composition Age-specific Fertility Rates (ASFR) Number of births to women in a particular age group, divided by the number of women in that age group. The age groups used are: 15-19, 20-24,.45-49. The data refer to five-year periods running from 1 July to 30 June of the initial and final years.
Age composition Mean Age of Childbearing (MAC) The average age of mothers at the birth of their children if women were subject throughout their lives to the age-specific fertility rates observed in a given year. It is expressed as years.
