Population estimates relate to the population as of 30th June each year, and therefore are often referred to as mid-year estimates. Estimates of the population aged 85 and over in Northern Ireland provide a further age breakdown of those aged 90 and over, by single year of age up to 104 years, and collectively for those aged 105 and over. These statistics contribute to the production of population projections and life expectancy statistics for Northern Ireland, all of which are of policy interest because of the implications for pensions and the delivery of front line services for the older population such as housing, transport and health care.
