Dublin is the largest city in Ireland
A population density map of County Dublin
As of the 2022 census, the population of Dublin was 1,458,154, an 8.4% increase since the 2016 Census. The county's population first surpassed 1 million in 1981, and is projected to reach 1.8 million by 2036.
Dublin is Ireland's most populous county, a position it has held since the 1926 Census, when it overtook County Antrim. As of 2022, County Dublin has over twice the population of County Antrim and two and a half times the population of County Cork. Approximately 21% of Ireland's population lives within County Dublin, 28% if only the Republic of Ireland is counted. Dublin has more people than the combined populations of Ireland's 16 smallest counties.
With an area of just 922 km2 (356 mi2), Dublin is by far the most densely populated county in Ireland. The population density of the county is 1,582 people per square kilometre – over 7 times higher than Ireland's second most densely populated county, County Down in Northern Ireland.
During the Celtic Tiger period, a large number of Dublin natives (Dubliners) moved to the rapidly expanding commuter towns in the adjoining counties. As of 2022, approximately 27.2% (345,446) of Dubliners were living outside of County Dublin. People born within Dublin account for 28% of the population of Meath, 32% of Kildare, and 37% of Wicklow. There are 922,744 Dublin natives living within the county, accounting for 63.3% of the population. People born in other Irish counties living within Dublin account for roughly 11% of the population.
Between 2016 and 2022, international migration produced a net increase of 88,300 people. Dublin has the highest proportion of international residents of any county in Ireland, with around 25% of the county's population being born outside of the Republic of Ireland.
As of the 2022 census, 5.6 percent of the county's population was reported as younger than 5 years old, 25.7 percent were between 5 and 25, 55.3 percent were between 25 and 65, and 13.4 percent of the population was older than 65. Of this latter group, 48,865 people (3.4 percent) were over the age of 80, more than doubling since 2016. Across all age groups, there were slightly more females (51.06 percent) than males (48.94 percent).
In 2021, there were 16,596 births within the county. The average age of a first time mother was 31.9.
Migration[edit]

Over a quarter (25.2 percent) of County Dublin's population was born outside of the Republic of Ireland. In 2022, Dublin City had the highest percentage of non-nationals in the county (27.3 percent), and South Dublin had the lowest (20.9 percent). Historically, the immigrant population of Dublin was mainly from the United Kingdom and other European Union member states. Results from the 2022 census revealed that immigrants from non-EU/UK countries were the largest source of foreign-born residents for the first time, accounting for 12.9 percent of the county's population. Those from other European Union member states accounted for 8.3 percent of Dublin's population, and those from the United Kingdom a further 4.1 percent.
Prior to the 2000s, the UK was consistently the largest single source of non-nationals living in Dublin. After declining in the previous two census periods, the number of UK-born residents living in Dublin increased by 5.8 percent between 2016 and 2022. There was a large difference between the number of people living in Dublin who were born in the UK (58,586) and those who held sole-UK citizenship in the 2022 census (22,936).
This discrepancy can arise for a variety of factors, such as people born in Northern Ireland claiming Irish citizenship rather than UK citizenship, Irish people born in the UK who now live in Dublin, British people who have become natural citizens, and foreign residents of Dublin who were born in the UK but are not UK citizens. Depending on an individual's responses in the census, all of these examples could result in the country of birth being registered by the CSO as the United Kingdom, but nationality being registered as Irish or a third country.
Following its accession to the EU, the Polish quickly became the fastest growing immigrant community in Dublin. Just 188 Poles applied for Irish work permits in 1999. By 2006 this number had grown to 93,787. After the 2008 Irish economic downturn, as many as 3,000 Poles left Ireland each month. Despite this, Poles remain one of Dublin's largest foreign-born groups. In contrast to more recent arrivals, a large percentage of Dublin's Polish citizens (30.9 percent) also hold Irish citizenship.

Outside of Europe, Indians and Brazilians are the predominant foreign-national groups. As of 2022, Indians were the fastest growing major immigrant group in Dublin, and they are now the county's second largest foreign-born group after the UK. Dublin's Indian community grew by 155.2 percent between 2016 and 2022. There were 29,582 Indian-born residents within Dublin as of 2022, up from 9,884 in the 2011 census. The influx of Indians is driven in part by multinational tech companies such as Microsoft, Google and Meta who have located their European headquarters within the county, in areas such as the Silicon Docks and Sandyford. In August 2020, the first dedicated Hindu temple in Ireland was built in Walkinstown.
The number of Brazilian citizens living in Dublin more than tripled between 2011 and 2022, from 4,641 to 16,441. This increase is mainly a result of Ireland's participation in the Brazilian government's Ciência sem Fronteiras programme, which sees thousands of Brazilian students come to study in Ireland each year, many of whom remain in the country afterwards.
Although not fully captured during the census period, Dublin also houses a significant number of Ukrainian refugees under the Temporary Protection Directive. As of October 2023, the number of Ukrainians living in emergency accommodation within the county is estimated to be around 14,000.
Ethnicity[edit]
According to the Central Statistics Office, in 2022 the population of County Dublin self-identified as:
80.4% White (68.0% White Irish, 12.0% Other White Background, 0.4% Irish Traveller)
5.8% Asian
3.0% Mixed background
2.2% African
8.5% Not stated
In terms of total numbers, Dublin has the largest non-white population in Ireland, with an estimated 158,653 residents, accounting for 11.1% of the county's population. Over two-fifths (42.2 percent) of Ireland's black residents live within the county. In terms of percentage of population, Fingal has the highest percentage of both black (3.6 percent) and non-white (12.4 percent) residents of any local authority in Ireland. Conversely, Dún Laoghaire–Rathdown in the south of the county has one of Ireland's lowest percentages of black residents, with only 0.77% of the population identifying as black in 2022. 43.3% of Ireland's multiracial population lives within County Dublin. Those who did not state their ethnicity more than doubled between 2016 and 2022, from 4.1% to 8.5%.

St Patrick's Cathedral, founded in 1191
The largest religious denomination by both number of adherents and as a percentage of Dublin's population in 2022 was the Roman Catholic Church, at 57.4 percent. All other Christian denominations including Church of Ireland, Eastern Orthodox, Presbyterian and Methodist accounted for 8.1 percent of Dublin's population. Together, all denominations of Christianity accounted for 65.5 percent of the county's population.
In the 2022 census, Dún Laoghaire–Rathdown is the least religious local authority in Ireland, with 23.9 percent of the population declaring themselves non-religious, followed closely by Dublin city (22.6 percent). In the county as a whole, those unaffiliated with any religion represented 20.1 percent of the population, which is the largest percentage of non-religious people of any county in Ireland. A further 9.1 percent of the population did not state their religion, up from just 4.1 percent in 2016.
Of the non-Christian religions, Islam is the largest in terms of number of adherents, with Muslims accounting for 2.6% of the population. After Islam, the largest non-Christian religions in 2022 were Hinduism (1.4 percent) and Buddhism (0.27 percent). While relatively small in absolute terms, County Dublin contains over half of Ireland's Hindu (58.7 percent) residents, and just under half of its Eastern Orthodox (45.3 percent), Islamic (45.0 percent) and Buddhist (41.7 percent) residents.
Dublin and its hinterland has been a Christian diocese since 1028. For centuries, the Primacy of Ireland was disputed between Dublin, the social and political capital of Ireland, and Armagh, site of Saint Patrick's main church, which was founded in 445 AD. In 1353 the dispute was settled by Pope Innocent VI, who proclaimed that the archbishop of Dublin was Primate of Ireland, while the archbishop of Armagh was titled Primate of All Ireland. These two distinct titles were replicated in the Church of Ireland following the Reformation.
Historically, County Dublin was the epicentre of Protestantism in Ireland outside of Ulster. The 1891 census show that the county was 21.4 percent Protestant towards the end of the 19th century. By the 1911 census this had gradually declined to around 20% due to poor economic conditions, as Dublin Protestants moved to industrial Belfast. Following the War of Independence (1919–1921), Dublin's Protestant community went into a steady decline, falling to 8.5 percent of the population by 1936.
Between 2016 and 2022, the fastest-growing religions in Dublin were Hinduism (148.9 percent), Eastern Orthodox (51.6 percent), and Islam (27.9 percent), while the most rapidly declining religions were Evangelicalism (−10.4 percent), Catholicism (−8.7 percent), Jehovah's Witnesses (−5.9 percent) and Buddhism (−5.4 percent).
Metropolitan area[edit]
Dublin city[edit]
The boundaries of Dublin City Council form the urban core of the city, often referred to as "Dublin city centre", an area of 117.8 square kilometres. This encompasses the central suburbs of the city, extending as far south as Terenure and Donnybrook; as far north as Ballymun and Donaghmede; and as far west as Ballyfermot. As of 2022, there were 592,713 people living within Dublin city centre. However, as the continuous built-up area extends beyond the city boundaries, the term "Dublin city and suburbs" is commonly employed when referring to the actual extent of Dublin.
Dublin city and suburbs[edit]
A map of Greater Dublin's defined boundaries
Dublin city and suburbs is a CSO-designated urban area which includes the densely populated contiguous built-up area which surrounds Dublin city centre. As of the 2022 census, Dublin city and suburbs encompassed 345 km2, expanding in size by 8.7 percent (or 27.5 km2) since the 2016 census. The population of Dublin city and suburbs grew from 1,173,179 in 2016 to 1,263,219 in 2022, an increase of 7.7 percent.
Following the 2022 census, Dublin city and suburbs was designated a cross-county settlement for the first time, as the CSO included the Kribensis Manor housing development within the contiguous built-up area of the city. The houses are located in County Meath, along the R149 road between Hilltown and the village of Clonee.
Approximately 87% of County Dublin's population lives within Dublin city and suburbs as of the 2022 census. The remainder of the county covers roughly two thirds of Dublin's land area, but is home to just 196,140 people.
Dublin metropolitan area[edit]
As the city proper does not extend beyond Dublin Airport, nearby towns such as Swords, Donabate, Portmarnock and Malahide are not considered part of the city, and are recorded by the CSO as separate settlements. However, under Ireland's National Planning Framework, these towns are considered part of the Dublin Metropolitan Area Strategic Plan (MASP). The MASP also includes towns outside of the county, such as Naas, Leixlip and Maynooth in County Kildare, Dunboyne in County Meath, and Bray, Kilmacanogue and Greystones in County Wicklow, but does not include Balbriggan, Lusk, Rush or Skerries, which are located in the far north of County Dublin.
Greater Dublin Area[edit]
The Greater Dublin Area (GDA) is a commonly used planning jurisdiction which extends to the wider network of commuter towns that are economically connected to Dublin city. The GDA consists of County Dublin and its three neighboring counties, Kildare, Meath and Wicklow.
With a population of 2.1 million and an area of 6,986 square kilometres, it contains 40% of the population of the State, and covers 9.9% of its land area.
