This feature layer was created using Census 2016 data produced by the Central Statistics Office (CSO) and Local Electoral Area boundary data (generalised to 20m) produced by Tailte Éireann. The layer represents Census 2016 theme 3.2, Irish speakers aged 3+ by frequency of speaking Irish. Attributes include population breakdown by frequency of speaking Irish and sex (e.g. daily within education system - males, weekly only outside the education system - females). Census 2016 theme 3 represents Irish Language. The Census is carried out every five years by the CSO to determine an account of every person in Ireland. The results provide information on a range of themes, such as, population, housing and education. The data were sourced from the CSO.For the purposes of County Council and Corporation elections each county and city is divided into Local Electoral Areas (LEAs) which are constituted on the basis of Orders made under the Local Government Act, 1941. In general, LEAs are formed by aggregating Electoral Divisions. However, in a number of cases Electoral Divisions are divided between LEAs to facilitate electors. The current composition of the LEAs have been established by Statutory Instruments No’s 427-452/2008, 503-509/2008 and 311/1998.

This dataset provides Census 2021 estimates that classify usual residents aged three and over in Northern Ireland by their main language. The estimates are as at census day, 21 March 2021. The main language classification used is a 19-category classification corresponding to the tick box options and write-in responses on the census questionnaire with at least 1,000 responses.

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.
