CPRD Aurum Civil Registrations of Death January 2026

Data source

The Office for National Statistics (ONS) collects and publishes official statistics related to the economy, population, and society in the UK.
Civil Registrations of Death relates to information recorded on UK death certificates.

Data contents

Civil Registrations of Death data from the ONS includes information on the official date and causes of death, coded using ICD codes. Please note that late registration for some deaths means that the proportion of deaths captured is lower for the last year of the coverage period, and this proportion is likely to differ by age at death and cause of death. This is especially pronounced for the last 1-2 weeks of available death data which shows an under count of the total number of deaths as these data do not capture those where the registration of a death has been delayed (e.g. deaths referred to coroners in England, Wales and Northern Ireland, which cannot be registered until investigations have been concluded, and can result in delays of months or years).

For more information please refer to the ONS User guide to mortality statistics, the ONS analysis exploring the impact of registration delays on mortality statistics and the associated dataset used for this report.
