More Information A death cohort is the number of deaths that have been registered or occurred in a calendar year which can be linked to the corresponding birth registration. A birth cohort is the number of births that have occurred in a calendar year which are then linked to their corresponding birth notification or death registration. Data for deaths on death cohort is released earlier than birth cohort due to the timing of the extracts. Please refer to Annex C for more information on this.
