Births and fertility

The LS includes birth information taken from the annual ONS birth file, which contains information on all births (live and stillbirths) registered in England and Wales. Combining LS census data with birth information gives an estimate of the population and the number of births in the period. This guidance aims to outline the fertility data that are available in the LS and show how to calculate measures of population fertility using the LS.
