Estimates of the Population Aged 85 and Over, Northern Ireland

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.

Additional Information

Population estimates for those aged 85-89 in this dataset are consistent with the published mid-year population estimates. Previously published estimates for the highest age group (90 and over) are distributed into single years of age up to 105 and over by incorporating death registration data within the internationally recognised Kannisto-Thatcher Survivor Ratio Method. Further information on the Kannisto-Thatcher Survivor Ratio Method is available at:

It should be noted that the Kannisto-Thatcher Survivor Ratio Method gives rise to minor revisions to the age distribution within the aged 90 and over category as new information on actual deaths becomes available. Accordingly, estimates for the 90 and over category in all years are slightly revised annually as the estimates are updated. Further information is available on the Estimates of the Population Aged 85 and Over release page:
