Preliminary results from the 2022 Census of Population reported a population of 5.12 million persons using the de facto definition of population, i.e. all persons present in the State on Census night. This differs by 23,300 from the population estimates contained in this release which have been compiled using the usual residence concept. It is planned to revise the usual residence estimates for the years 2017 to 2022 (i.e. the period between Censuses) following a thorough analysis of the final detailed Census results when they become available in 2023.
