The Office for National Statistics (ONS) compiles mortality statistics which are based on registrations of deaths. These registrations are made by local registrars of births and deaths, and in most cases are required within five days of the death occurrence.
Registrars supply details of all deaths to ONS each week. ONS processes and tabulates the data, publishing figures weekly, monthly, quarterly and annually. Monthly data will usually appear within the following month and annual data within five to eighteen months following the reference year, depending on the publication and the basis of presentation - registrations or occurrences in the reference year.
Main analyses of mortality data are by age, sex, area of residence and cause of death.
