Mortality (Death registration)

The Northern Ireland Mortality Dataset contains information on deaths registered in Northern Ireland (NI). The data is collected from death certificates and information provided by GPs and other Health and Social Care Northern Ireland (HSCNI) providers. The data is provided with a three month delay from the date of registration and the information will relate to the latest certificate. This means the cause of death for an individual may be updated in cases where the death undergoes further investigation, for example by a coroner. The data can be linked to other health-related datasets using patient Health and Care Number (HCN). HCN is not usually supplied along with death certificate data. This is added after matching to medical records, meaning that not all records will have a HCN to allow linkage to other health datasets.
