These statistics contain the first phase of main statistics results from Census 2021. This phase provides estimates for a number of census topics, including passports held, ethnic group, national identity, language, and religion.

Data are available for Northern Ireland and the 11 Local Government Districts.

This table provides Census 2021 estimates that classify people by National identity (8 categories) by Religion or religion brought up in for Northern Ireland. The table contains 32 counts.

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.

'Religion' indicates religion, religious denomination or body. 'Catholic' includes those who gave their current religion as Catholic or Roman Catholic.

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.

The UK censuses took place on 21st April 1991. They were run by the Census Office for Northern Ireland, General Register Office for Scotland, and the Office of Population and Surveys for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.

Statistics from the UK censuses help paint a picture of the nation and how we live. They provide a detailed snapshot of the population and its characteristics, and underpin funding allocation to provide public services.

The aggregate data produced as outputs from censuses in Northern Ireland provide information on a wide range of demographic and socio-economic characteristics. They are predominantly a collection of aggregated or summary counts of the numbers of people or households resident in specific geographical areas possessing particular characteristics.

Small Area Statistics for Northern Ireland have been made available as a result of a collaborative project between the Census Office for Northern Ireland, ESRC and Queen's University, Belfast. The Small Area Statistics (SAS) for Northern Ireland are the principal digital output from the 1991 Northern Ireland Census. They are broadly similar in structure to the 1991 Great Britain Census. They constitute the most detailed resource of 100 per cent sample socio-demographic data in Northern Ireland, with all variables available at a high level of spatial resolution (Enumeration District).

The 2021 UK Census was the 23rd official census of the United Kingdom. The UK Census is generally conducted once every 10 years, and the 2021 censuses of England, Wales, and Northern Ireland took place on 21 March 2021. In Scotland, the decision was made to move the census to March 2022 because of the impact of the coronavirus pandemic. The censuses were administered by the Office for National Statistics (ONS), the Northern Ireland Statistics and Research Agency (NISRA) and National Records of Scotland (NRS), respectively. In England and Wales, Census 2021 was the first census with a digital-first design, encouraging participants to respond online rather than on a paper questionnaire.

Topics covered in the 2021 UK Census included:

• demography and migration
• ethnic group, national identity, language and religion
• labour market and travel to work
• housing
• education
• health, disability, and unpaid care
• Welsh and other languages
• UK armed forces veterans
• sexual orientation and gender identity.

A census of population is held every ten years in the UK, in England and Wales it is undertaken by the Office for National Statistics (ONS), in Scotland by the National Records of Scotland (NRS) and in Northern Ireland by the Northern Ireland Statistics and Research Agency (NISRA).

In England, Wales and Northern Ireland the latest census was taken on Sunday 21st March 2021. Due to issues around COVID-19, the census in Scotland was held a year later on 28th June 2022.

The census asks questions about you, your household and your home. In doing so, it helps to build a detailed snapshot of our society. Information from the census helps the government and local authorities to plan and fund local services, such as education, doctors' surgeries and roads.

Topics covered by the data released by the Census agencies include -

Demography and migration, UK armed forces veterans, ethnicity, national identity, language, religion, labour market, housing, sexual orientation, gender identity, education, health, disability and unpaid care.

The data in this series covers aggregate data at geographies from country level down to Output Area. Due to disclosure control (data can be blurred, changed or withheld to protect anonymity) not all datasets are available at all levels.

The health of the farming community in Northern Ireland (NI) requires further research as previous mortality studies have reported contradictory results regarding farmers’ health outcomes compared against other occupations and the general population. This study collated the NINIS area-level farm census with the population census information across 582 non-overlapping wards of NI to compile three mortality datasets (2001, 2011, and pooled dataset) (NISRA 2019). These datasets allow future researchers to investigate the influence of demographic, farming, and economic predictors on all-cause mortality at the ward level. The 2001 and 2011 mortality datasets were compiled for cross-sectional analyses and subsequently pooled for longitudinal analyses. Findings from these datasets will provide evidence of the influence of farming intensity scores on death risk within the wards for future researchers to utilise, and this will aid in the understanding of socio-ecological variables’ additive contribution to the risk of death at the ward level within NI. This data report is of interest to the One Health research community as it standardises the environment−human−animal data to pave the way towards a new One Health research paradigm. For example, future researchers can use this nationally representative data to investigate whether agriculturally saturated wards have a higher mortality risk than non-agriculturally based wards of NI.

They were run by the Northern Ireland Statistics & Research Agency (NISRA), National Records of Scotland (NRS), and the Office for National Statistics (ONS) for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.

The 2011 Census Microdata Individual Safeguarded Sample (Local Authority): England and Wales data collection forms part of the statistical outputs from the 2011 UK Census. A safeguarded microdata sample of individuals has been identified as a key Census user requirement, and was highlighted as part of a report specifying microdata products from the 2011 Census written by an expert user, Dr. Jo Wathan from the University of Manchester.

The purpose of a safeguarded sample of individuals is to be able to disseminate a detailed microdata file without onerous licensing conditions, by reducing the overall amount of detail compared to the secure samples. Whilst supplying sufficient detail on core variables to fulfil the intended aim of the microdata products, the safeguarded sample is a valuable multi-purpose research file that will be used on a wide range of projects. (For Censuses prior to 2011, these data may have been referred to as 'Samples of Anonymised Records', or SARSs.)

In total, five microdata samples are proposed from the 2011 Census:

• one public, a Teaching File of individuals (see SN 7613);
• two safeguarded, one file of individuals at regional level (see SN 7605) and one at local authority level (this study, SN 7682);
• and two secure, one file of households and one of individuals

This safeguarded sample is of 5% of the total population at Local Authority level, and contains a similar level of detail to the equivalent End User Licence Census 2001 Microdata samples. These samples have a low risk of disclosure; but not nil. Registered UK Data Service Census users can download the data to their laptops after agreeing terms and conditions that include constraints on data management under remote storage conditions.

Further information can be found on the Office for National Statistics Census microdata webpage.

Corresponding Regional and Local Authority level data for Northern Ireland are held under SNs 7769 and 7770, and for Scotland under SNs 7834 and 7835.
