Northern Ireland Census 2021 - MS-E02: Household size

This dataset provides Census 2021 estimates that classify households in Northern Ireland, with at least one usual resident, by household size. It also includes an estimate of the number of usual residents living in households and average household size. The estimates are as at census day, 21 March 2021.

The census collected information on the usually resident population of Northern Ireland on census day (21 March 2021). Initial contact letters or questionnaire packs were delivered to every household and communal establishment, and residents were asked to complete online or return the questionnaire with information as correct on census day. Special arrangements were made to enumerate special groups such as students, members of the Travellers Community, HM Forces personnel etc. The Census Coverage Survey (an independent doorstep survey) followed between 12 May and 29 June 2021 and was used to adjust the census counts for under-enumeration.

Average household size is a calculation of the usually resident population living in households divided by the number of households.
