This dataset provides Census 2021 estimates that classify households in Northern Ireland by the diversity in ethnic group of household members in different relationships. 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.

In 2024, there were 435,000 people aged between 40 and 44 in the Republic of Ireland, the most common age group among those provided in this year.

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 2.2, the population usually resident in Ireland by ethnic or cultural background. Attributes include population breakdown by ethnicity or cultural background (e.g. Asian or Asian Irish, White Irish). Census 2016 theme 2 represents Migration, Ethnicity and Religion. 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.

Usually resident population by ethnic or cultural background by Small Area. (Census 2022 Theme 2 Table 2 )Census 2022 table 2.2 is the population usually resident in Ireland by ethnic or cultural background. Details include population by ethnicity or cultural background. Census 2022 theme 2 is Migration, Ethnicity, Religion and Foreign Languages.Census Small Areas are the lowest level of geography for the dissemination of Census data and typically contain between 50 and 200 dwellings. They are generally comprised of complete neighbourhoods or townlands and they nest within CSO Electoral Divisions.Census 2022 Small Areas have been redrawn to ensure they remain consistent with the principle of data protection and are relatively comparable in size. This redraw was necessary following changes in population size and distribution between 2016 and 2022 and was done by the CSO with support from Tailte Éireann.Small Areas were first published for Census 2011 following work undertaken by the National Institute of Regional and Spatial Analysis (NIRSA) on behalf of Tailte Éireann and in consultation with the CSO.Coordinate reference system: Irish Transverse Mercator (EPSG 2157).

The 2021 Northern Ireland Census marked the first time since records began where the Catholic share of the population was larger than the combined Protestant share. In 2021, over 42 percent of the population classified themselves as Catholic or from a Catholic background, in comparison with 37 percent classified as Protestant or from a Protestant background. Additionally, the share of the population with no religion (or those who did not answer) was 19 percent; larger than any individual Protestant denomination. This marks a significant shift in demographic and societal trends over the past century, as Protestants outnumbered Catholics by roughly 2:1 when Northern Ireland was established in the 1920s. Given the Catholic community's historic tendency to be in favor of a united Ireland, many look to the changing religious composition of the population when assessing the potential for Irish reunification. Religion's historical influence A major development in the history of British rule in ireland was the Plantation of Ulster in the 1600s, where much of the land in the north (historically the most rebellious region) was seized from Irish Catholics and given to Protestant settlers from Britain (predominantly Scots). This helped establish Protestant dominance in the north, created a large section of the population loyal to the British crown, and saw a distinct Ulster-Scots identity develop over time. In the 1920s, the republican movement won independence for 26 of Ireland's 32 counties, however, the six counties in Ulster with the largest Protestant populations remained part of the UK, as Northern Ireland. Following partition, structural inequalities between Northern Ireland's Protestant and Catholic communities meant that the Protestant population was generally wealthier, better educated, more politically empowered, and had better access to housing, among other advantages. In the 1960s, a civil rights movement then emerged for equal rights and status for both sides of the population, but this quickly turned violent and escalated into a the three-decade long conflict now known as the Troubles.

The Troubles was largely fought between nationalist/republican paramilitaries (mostly Catholic), unionist/loyalist paramilitaries (mostly Protestant), and British security forces (including the police). This is often described as a religious conflict, however it is more accurately described as an ethnic and political conflict, where the Catholic community generally favored Northern Ireland's reunification with the rest of the island, while the Protestant community wished to remain in the UK. Paramilitaries had a large amount of support from their respective communities in the early years of the Troubles, but this waned as the conflict progressed into the 1980s and 1990s. Demographic and societal trends influenced the religious composition of Northern Ireland's population in these decades, as the Catholic community had higher fertility rates than Protestant communities, while the growing secularism has coincided with a decline in those identifying as Protestant - the dip in those identifying as Catholic in the 1970s and 1980s was due to a protest and boycott of the Census. The Troubles came to an end in 1998, and divisions between both sides of the community have drastically fallen, although they have not disappeared completely.

Usually resident population by ethnic or cultural background by NUTS3. (Census 2022 Theme 2 Table 2 )Census 2022 table 2.2 is the population usually resident in Ireland by ethnic or cultural background. Details include population by ethnicity or cultural background. Census 2022 theme 2 is Migration, Ethnicity, Religion and Foreign Languages. The Nomenclature of Territorial Units for Statistics (NUTS) were created by Eurostat in order to define territorial units for the production of regional statistics across the European Union. In 2003 the NUTS classification was established within a legal framework (Regulation (EC) No 1059/2003).Changes made under the 2014 Local Government Act prompted a revision of the Irish NUTS 2 and NUTS 3 Regions. The main changes at NUTS 3 level were the transfer of South Tipperary from the South-East into the Mid-West NUTS 3 region and the movement of Louth from the Border to the Mid-East NUTS 3 Region. NUTS 3 Regions are grouped into three NUTS 2 Regions (Northern and Western, Southern, Eastern and Midland) which correspond to the Regional Assemblies established in the 2014 Local Government Act. The revisions made to the NUTS boundaries have been given legal status under Commission Regulation (EU) 2016/2066.Coordinate reference system: Irish Transverse Mercator (EPSG 2157). These boundaries are based on 20m generalised boundaries sourced from Tailte Éireann Open Data Portal. NUTS3 Regions 2015This dataset is provided by Tailte Éireann

The diverse ethnic diets in Ireland intake dataset was conducted as part of the FNS-Cloud project (Field Lab 1) in 2020 and 2021. This study aimed to validate the Foodbook24 tool version 2 by comparing 24-hour dietary recalls collected using Foodbook24 against interviewer-led recalls in Irish, Polish, Chinese and Brazilian adults (≥18 years) living in Ireland. Participants completed one self-administered dietary recall using Foodbook24 and one interviewer-led dietary recall with a trained researcher on the same day. Two weeks later the process was repeated in the opposite order. In total n=136 participants were recruited: n=32 Brazilian, n=53 Irish, n=32 Chinese, n=19 Polish. Data are contained in the following files: 1) dietary intake food file containing individual food, beverage and supplement intake for each day of data collection 2) demographic, lifestyle (physical activity (IPAQ), smoking status, alcohol consumption) and anthropometric (self-reported weight/height) file 3) Food choice questionnaire file
