Demographics of Northern Ireland

Northern Ireland is the smallest of the four parts of the United Kingdom in terms of both area and population, containing 2.9% of the total population and 5.7% of the total area of the United Kingdom. It is the smaller of the two political entities on the island of Ireland by area and population, the other being the Republic of Ireland. Northern Ireland contains 27.1% of the total population and 16.75% of the total area of the island of Ireland.

The Belfast Metropolitan Area dominates in population terms, with over a third of the inhabitants of Northern Ireland.

When Northern Ireland was created, it had a Protestant majority of approximately two-to-one,^[2][3][4] unlike the Republic of Ireland, where Catholics were in the majority.^[5] The 2001 census was the first to show that the Protestant and other (non-Catholic) Christian share of the population had dropped below 50%, but 53.1% still identified as being from a Protestant or other Christian background. In the 2011 census, this dropped to 48.4%.^[6][4] In 2021, the recorded number of Catholics by background (45.7%) overtook the Protestant and other Christian by background share (43.48%), becoming the plurality, with no group in the overall majority.^{[7][8][9][10]}

Its people speak Irish (Gaelic), Ulster Scots and Ulster English which is itself heavily influenced by the Scots language of which Ulster Scots is a dialect. In addition the Ulster dialect of Irish (Gaelic) also has a closer connection to Scottish Gaelic than other Irish (Gaelic) dialects. This is both because of historic links with Scotland going back centuries, and because of settlements of lowland Scots Protestants in Ulster in the 17th century, such as the Plantation of Ulster.

Also unlike the Republic, a large proportion of people in Northern Ireland have a British national identity, although a significant minority identifies as Irish. Many people in Northern Ireland have a Northern Irish identity, whether in addition to a British or Irish identity or by itself.

Population density

Population density of Northern Ireland based on 2021 census

Northern Ireland's population density is 133 people per square kilometre - comparable to European countries such as Denmark and the Czech Republic. If Northern Ireland were a sovereign state, it would have the 16th-highest population density in Europe.

It has a higher population density than Scotland (70 people per km²), but less than England and Wales (434 per km² and 153 per km² respectively).^[15]

Belfast is the most population-dense of the 11 local government districts by far, at 2,617 per km² - it has the highest population (345,418)^[16] and least land area (133km²)^[17] of any district, and takes in Belfast City itself as well as much of the Metropolitan Castlereagh settlement (formerly part of the Castlereagh local government district before 2015).

By contrast, Fermanagh and Omagh is the least dense, with the lowest population (116,812)^[18] and greatest land area (2,836km²). It includes all of Northern Ireland's least-populous county, Fermanagh (except the townland of Killybane near Fivemiletown), and the largely rural former Omagh district.

Of the 80 District Electoral Areas that make up the local government districts, Botanic in Belfast has the highest population density at 4,653 people per km^2[19], as well as being the most populous DEA (49,727 people in 2021).^[20] The DEA includes Belfast city centre, Queen's University, and much of the city's student population.

By contrast, Erne West in Fermanagh and Omagh has the lowest population density of any DEA, with 20 people per km², as well as being the least populous DEA (14,661 people in 2021). Erne West is largely made up of and surrounded by mountainous terrain. Lough Erne forms a geographical barrier between it and the rest of Northern Ireland, with only a few roads around and over the lough. The largest settlement, Bellanaleck, a small village near Enniskillen, is home to only 714 people,^[21] and is apart from the other small villages spread through Erne West's large, narrow area.

The 217 wards with the highest population density which make up 50.2% of the population. They have a combined area of 460.1km², 3.3% of Northern Ireland's total area. Overlaid: railways (black), rail stations (yellow), motorways (blue), dual carriageways (green).

The 216 contiguous wards with the highest population density, which make up 50.02% of the population. They have a combined area of 1,299km², 9.4% of Northern Ireland's total area. Overlaid: railways (black), rail stations (red), motorways (blue), dual carriageways (green).

As of 2021, 50.2% of Northern Ireland's population lived in the 217 most population-dense electoral wards (around 47% of Northern Ireland's 462 wards). The 217 wards have an area of 460.1km², 3.3% of Northern Ireland's total area. Of these 217 wards, 99 are a contiguous area covering most of Belfast, Castlereagh, Lisburn and Newtownabbey. These 217 wards are highlighted in red on the map.

These wards cover part or all of the 28 largest settlements in Northern Ireland, as well as Warrenpoint, Donaghadee, Ballynahinch, Moira, Maghera and Coalisland. The vast majority of these wards contain or are near a motorway, dual carriageway or train station. Considering this, the most remote wards are the Portora and Erne wards in Ennskillen, which are 30 miles from the A4 dual carriageway near Ballygawley.

Furthermore, 50.02% of Northern Ireland's population lived in the most population-dense contiguous area of 216 electoral wards. These 216 wards have an area of 1,299km², 9.4% of Northern Ireland's total area. These 216 wards are highlighted in purple on the map. These wards cover part or all of the 10 largest settlements, and almost entirely track Northern Ireland's rail lines, motorways and dual carriageways. The exceptions are a spur towards Armagh city; and a string of villages between Ballymena and Limavady.

The electoral wards in Northern Ireland with the highest and lowest population density are listed in the table below:

Place of birth

Place of birth by age group^[24]

Map showing the percentage of the population born outside Northern Ireland according to the 2021 census.

In 2001, 91.0% of the population were born in Northern Ireland, 7.2% were born in other parts of the UK and Ireland, and 1.8% were born elsewhere. By 2021, the proportion of immigrants from outside the UK and Ireland had risen to 6.6%, while the proportion born within other parts of the UK and Ireland had fallen to 6.9%. The highest number of non-British/Irish immigrants are in Belfast City Council, followed by Armagh City, Banbridge and Craigavon Borough Council and Mid Ulster District Council. The town of Dungannon in Mid Ulster District Council has a bigger share of immigrants than any town in Northern Ireland, while Derry City and Strabane has the smallest share of immigrants.^[25]

Emigration

Detailed statistic on births are available between 1887 and 2022 in Birth tables ^[30] and deaths between 1955 and 2022 in Death tables ^[31]

Using deaths and births between 1955 and 2021, and the number of those from the 2021 census whose country of birth is Northern Ireland, we can estimate emigration for those aged under 66 by subtracting the total of the number of deaths and the number of those born in Northern Ireland who are still living there.

Northern Irish emigration estimates

	All ages	18-66 year olds
Births 1955-2021	1,801,552	1,353,624
Deaths 1955-2021 among those born 1955-2021	78,914	76,226
Country of birth is Northern Ireland in 2021 Census, ages 0-66	1,389,081	965,538
Estimated Emigration	333,557	311,860
Estimated Emigration as a percentage of births	18.5%	23.0%

This gives an estimate of 18.5% of all people born since 1955 have emigrated, or 23% of adults aged 18-66. This is an estimate of the minimum amount of emigration, since deaths are not broken down by country of birth, so some of those will not have been born in Northern Ireland. Most deaths occur in the over 50 and currently about 12.5% of those aged 50 and over were born outside Northern Ireland. Adjusting the number of deaths downwards by 12.5%, we can estimate an emigration rate of 18.5 to 19% for all ages, and 23.0% to 23.7% for adults aged 18-66.

Doing the same analysis by age, we see that this is consistent with the actual number of those born in Northern Ireland from the 2021 England/Wales census,^[32] where about 40% of emigrants have settled in England or Wales.

Languages spoken

Main article: Languages of Northern Ireland

English is by far the most commonly spoken language in Northern Ireland. Two regional languages of Northern Ireland, Irish and Ulster Scots, are protected under the European Charter for Regional or Minority Languages. Several other languages are spoken by immigrants to Northern Ireland, the most common of which is Polish.

A question about knowledge of Irish was reintroduced to the census in 1991, for the first time since 1911. In 2011, the census question was modified to ask about Ulster Scots alongside Irish.^[46]

Education

Northern Ireland has a highly educated and literate population, particularly among the younger generations.

The following shows the educational attainment, shown by highest qualification received, at different ages for adults, in the 2021 census^[55]

• Highest Qualification received - Level 1 to Level 4
• 
  Highest qualification received by age
• 
  Female highest qualifications by age
• 
  Male highest qualifiations received by age

• Apprenticeships and No qualifications
• 
  Apprenticeships by age
• 
  No qualifications by age

The census defines the levels as follows:

• Level 1: 1 to 4 GCSEs, O levels, CSEs (any grades); 1 AS Level; NVQ level 1; or equivalent
• Level 2: 5 or more GCSEs (A*-C or 9-4), O levels (passes) CSEs (grade 1); 1 A level, 2-3 AS Levels; NVQ level 2, BTEC General, City and Guilds Craft; or equivalent
• Level 3: 2 or more A Levels, 4 or more AS Levels; NVQ Level 3, BTEC National, OND, ONC, City and Guilds Advanced Craft; or equivalent
• Level 4: Degree (BA, BSc), foundation degree, NVQ Level 4 and above, HND, HNC, professional qualifications (teaching or nursing, for example), or equivalent
• Other: Other qualifications, equivalent unknown

Younger adults, aged 18-30, are the highest ever qualified group. Just under 50% of that age group who have reached university graduation age (around 23 years old) have achieved a Level 4 or above qualification. This is about 10% higher than those aged 30-40. The number of those without qualifications is the lowest in 18-30 group.

There is a large gender gap with 10% more females than males receiving Level 4 or above qualification. About 55% of women in their 20s have achieved Level 4.

The number of young adults with no qualifications is less than 8%, compared to an overall 23.8%. There has been a decrease in the number of people with apprenticeships from about 20% of males over 70 to only 5% for 20-30 year olds.

Past Censuses

Questions about the highest academic qualification received has been asked since the 1991 census. The categorization of results has changed since 1991, but each prior census can be mapped to 2021 categories.

Apprenticeships were not tracked as separate categories in 1991 or 2001 and it's not certain whether they were counted as "No Qualifications". About 10% of those over 50 reported holding an apprenticeship in 2021. Currently apprenticeships have a large academic component, and are separated into "Intermediate", "Advanced," and "Higher" apprenticeships, and so are included as academic qualifications.^[57]

Mapping the past results to the 2021 categories, we see that the number of people with no qualifications has dropped considerably in each census, whereas the number of people with degrees or equivalent is nearly 4 times larger than in 1991.

For the first century that Northern Ireland existed, the majority or plurality of its population identified with Protestantism, and with its founding, the region was intended to have a permanent Protestant majority.^[64] With the 2021 census, Catholics outnumbered Protestants for the first time.

Northern Ireland is geographically polarized by religion. Catholics are concentrated in the west and border areas, and recently in Belfast. Protestants are concentrated in the east, in an east-west band across northern Armagh to northern Down, and north-south from the Antrim coast to north of Belfast. Belfast was once a majority Protestant city but became a Catholic plurality city between the 2001 and 2011 censuses.

The following table shows the religion stated by respondents to the 2001, 2011 and 2021 censuses.

"Religion" vs "Religion or Religion Raised In" (Religious Background)

Religion and Religion Raised in by age

The census included two questions related to religion: what religion, religious denomination or body do you belong to? and what religion, religious denomination or body were you brought up in?

This produced two sets of results, where the "current religion" is in all cases less than the "religion brought up in"

The difference between the two measurements is higher for Protestants than for Catholics, and is higher among younger people.

Geographically, using Religion instead of Religious Background doesn't change the areas where Catholic outnumber Protestants, or vice versa, but results in some regions where a majority turns into a plurality.

In Northern Ireland national identity is complex. Many in Northern Ireland have a British national identity and view the English, Scots and Welsh as fellow members of their common nation while regarding people from the Republic of Ireland as foreigners. Many others in Northern Ireland view people from the Republic of Ireland as being members of their common nation encompassing the island of Ireland and regard the English, Scots and Welsh as foreigners. Co-existing with this dichotomy is a Northern Irish identity, which can be held alone or, as is also the case with Englishness, Scottishness and Welshness, alongside a British identity, or alongside an Irish identity. A small number of people see themselves as being both British and Irish.

In the 2021 census respondents gave their national identity as follows.

Areas where less than 50% Catholics identify as Irish (green) and less than 50% Protestants identify as British (red)

Although there is a strong correlation between religion and national identity, Catholics tending to identify as Irish and Protestants tending to identify as British, this is not an absolute relationship, and the correlation is weaker amongst Catholics than it is amongst Protestants. Amongst Catholics, geography also plays an important role, with Catholics in heavily Protestant parts of Northern Ireland being more likely to call themselves British and less likely to call themselves Irish than Catholics in more Catholic areas of Northern Ireland. The reverse is true for Protestants, but to a lesser extent. However, the actual numbers are low for both those Protestants identifying as Irish and Catholics identifying as British, since it happens in areas where the respective religion is proportionally low.

In the 2021 census, Protestants outnumbered Catholics in 37 DEAs, down from 44 in 2011, while those considering themselves British outnumbered those who considered themselves Irish in 45 DEAs, down from 58 in 2011.

The majority of areas being British, despite the majority of areas being Catholic, is partly because Catholics were more likely to see themselves as British than Protestants were to see themselves as Irish (however this changed significantly between 2011 and 2021 - 9% vs. 4.8% respectively – in 2011 it was 13% vs 4% respectively), but is also partly because those of no religion were more likely to see themselves as British as see themselves as Irish. The non-religious tend to live in Protestant areas, suggesting that they are mostly of Protestant descent. In 2021, 47% of those professing no religion considered themselves British, while 12% considered themselves Irish. Members of the immigrant population, which includes many Poles, are also more likely to consider themselves Catholic.

Northern Irish identity was slightly more likely amongst Catholics than amongst Protestants, and it varied little according to geography.

The following metrics account for over 90% of the population in both 2011 and 2021. National Identity showed a large shift from British to Irish of 10% between 2011 and 2021.

	2011	2021	Change
British Only	39.9%	31.9%	-8.0%
British And Northern Irish	6.2%	8.0%	+1.8%
Irish Only	25.3%	29.1%	+3.9%
Irish And Northern Irish	1.1%	1.8%	+0.7%
Northern Irish Only	20.9%	19.8%	-1.1%

All DEAs showed an increase in Irish National Identity relative to British, with the lowest increase (3%) in the Court DEA, and the largest increase (22%) in the Castlereagh South DEA. Generally the largest increases were in the east, in and around Belfast.

Between 2011 and 2021, Catholics seeing themselves as British fell from 13% to 9%, while Protestants seeing themselves as Irish increased from 4% to 4.8%.

The shift from British to Irish can be seen from the plot comparing the age groups from the 2011 census with the same age cohort in the 2021 census. There was a swing towards Irish across all age cohorts, but it was 12-13% among younger adults (under 35 in 2021), approximately 2-6% among 35-64 (in 2021) year olds, and a much smaller 0.8% in the oldest age cohort.

People born in Northern Ireland have automatic British citizenship on the same basis and with the same provisions as those born elsewhere in the United Kingdom. Despite the Irish Government's withdrawal of its constitutional claim to Northern Ireland in 1999, those born in Northern Ireland are entitled to Irish citizenship, should they so choose. Because of this entitlement most people in Northern Ireland are able to get both a British passport and an Irish Passport. Through an agreement between the Irish Government and Post Office Ltd, post offices in Northern Ireland provide a service where customers can apply for an Irish passport, alongside their service where customers can apply for a British passport.

Significantly more Irish passports (+11.4%) and fewer British passports (-6.5%) were held in 2021 compared to 2011. Catholics in particular gave up their British passports (-10.9%) and now hold Irish passports (+16.7%), but there was also a small drop in the percentage of Protestants with British passports (-0.4%) and large increase in Protestants with Irish passports (+6.5%). Similarly "Other" and "No religion" British passport holders fell by 8.3% and 4.9% respectively, and Irish passport holder increased by 5.6% and 6.9% respectively.

In the 2021 census, respondents stated that they held the following passports,^[83] compared to 2011.^[84][85]
