The population of Wales doubled from 587,000 in 1801 to 1,163,000 in 1851 and had reached 2,421,000 by 1911. Most of the increase came in the coal mining districts, especially Glamorganshire, which grew from 71,000 in 1801 to 232,000 in 1851, and to 1,122,000 in 1911. ^[5] Part of this increase can be attributed to the demographic transition seen in most industrialising countries during the Industrial Revolution, as death-rates dropped and birth-rates remained steady. However, there was also a large-scale migration of people into Wales during the Industrial Revolution.

Current population

The 2021 census showed Wales' population to be 3,107,500, the highest in its history. ^[6] In 2011, 27 per cent (837,000) of the total population of Wales were not born in Wales, ^{[7] [8]} including 636,000 people (21 per cent of the total population of Wales) who were born in England. ^[9] The main population and industrial areas are in South Wales, including the cities of Cardiff, Swansea and Newport and the nearby valleys, with another significant population in the north-east around Wrexham and Flintshire.

Population density of Wales in 2011

According to the 2001 census, 96 per cent of the population was White British, and 2.1 per cent non-white (mainly of British Asian origin). ^[10] Most non-white groups were concentrated in Cardiff, Newport and Swansea. Welsh Asian and African communities developed mainly through immigration after the Second World War. ^[11] In the early 21st century, parts of Wales saw an increased number of immigrants settle from recent EU accession countries such as Poland, ^[12] though a 2007 study showed a relatively low number of employed immigrant workers from the former Eastern Bloc countries in Wales compared to other regions of the United Kingdom. ^[13]

The 2001 UK census was criticised in Wales for not offering Welsh as an option to describe respondents' national identity. ^[14] Partly to address this concern, the 2011 census asked the question "How would you describe your national identity?". Respondents were instructed to "tick all that apply" from a list of options that included Welsh. The outcome was that 57.5 per cent of Wales' population indicated their sole national identity to be Welsh; a further 7.1 per cent indicated it to be both Welsh and British. No Welsh national identity was indicated by 34.1 per cent. The proportion giving their sole national identity as British was 16.9 per cent, and another 9.4 per cent included British with another national identity. No British national identity was indicated by 73.7 per cent. 11.2 per cent indicated their sole national identity as English and another 2.6 per cent included English with another national identity. ^{[15] [16] [17]}

The 2011 census showed Wales to be less ethnically diverse than any region of 'England and Wales': ^[18] 93.2 per cent classed themselves as White British (including Welsh, English, Scottish or Northern Irish), 2.4 per cent as Other White (including Irish), 2.2 per cent as Asian (including Asian British), 1 per cent as Mixed, and 0.6 per cent as Black (African, Caribbean, or Black British). The lowest proportion of White British (80.3 per cent) was in Cardiff. ^{[17] [19]}

In 2001, a quarter of the Welsh population were born outside Wales, mainly in England; about 3 per cent were born outside the UK. The proportion born in Wales varies across the country, with the highest percentages in the South Wales valleys and the lowest in Mid Wales and parts of the north-east. In both Blaenau Gwent and Merthyr Tydfil, 92 per cent were Welsh-born, compared with only 51 per cent and 56 per cent in the border counties of Flintshire and Powys. ^[20] Just over 1.75 million Americans report themselves to have Welsh ancestry, as did 440,965 Canadians in Canada's 2006 census. ^{[21] [22]}

The total fertility rate (TFR) in Wales was 1.90 in 2011, ^[23] which is below the replacement rate of 2.1. The majority of births are to unmarried women (58 per cent of births in 2011 were outside marriage). ^[24] About one in 10 births (10.7 per cent) in 2011 were to foreign-born mothers, compared to 5.2 per cent in 2001. ^[25]

National identity

Main article: Welsh national identity

2011

A question on national identity was asked in the 2011 census: "What do you feel is your national identity?" Respondents could identify themselves as having one or more national identity.

An analysis of the 2011 data by Manchester University's Centre on Dynamics of Ethnicity revealed that: ^[37]

• 58% identified as "Welsh only"
• 16% identified as "British only"
• 12% identified as "English only"
• 7% identified as "Welsh and British"

The remainder chose other national identities. The Welsh-Caribbean population were the most likely to respond as "Welsh Only", at 59% of 11,099 citizens.

2018

A 2018 poll, commissioned by the BBC and carried out by YouGov, found that almost eight in 10 (79%) people in Wales identified strongly as British; while six in 10 (62%) identified strongly as Welsh. ^{[38] [39]}

2020

A 2020 YouGov poll asking a sample of 1110 people "Which, if any, of the following best describes the way you think of yourself?" found the following responses:

• 21% "Welsh not British"
• 17% "More Welsh than British"
• 22% "Equally Welsh and British"
• 9% "More British than Welsh"
• 17% "British not Welsh"
• 11% "Other"
• 3% "Don't know"

Summary

Total Welsh at all: 69%

Total at least more Welsh than British: 38%

Total at least more British than Welsh: 26% ^[40]

Population pyramid of Wales by ethnicity in 2021

According to the 2011 census, 2.2 million (73%) of usual residents of Wales were born there, two percent less than in 2001. The change can be attributed to both international and internal migration. In 2001, 590,000 (20%) of the population of Wales was born in England. In 2011, this had increased by one percent. ^[36] Nearly 418,000 people identified themselves as Welsh in 2001. The 1991, 2001 and 2011 census estimated the following ethnic groups:

• There are no solid statistics covering Christian denominations in Wales. However it is clear that the Presbyterian Church of Wales, ^[53] a Nonconformist denomination, and the Church in Wales, part of the Anglican Church, have historically been the largest. Important to Wales have been Nonconformist denominations, which became widespread in the 18th century, and Roman Catholicism until the 16th century. The translation of the Bible into Welsh by William Morgan in 1588 not only helped the survival of the Welsh language (after the Laws in Wales Acts effectively outlawed it in public life) but also enabled a faster uptake of Protestantism.
• A Jewish community has existed in Wales since the 13th century or earlier, but there are now only about 2,000 Jews left (since peaking at around 5,000 in 1913), and most live in the Cardiff area. There used to be enough Jews to sustain synagogues in valley communities like Merthyr Tydfil and Tredegar, but there are now only three active synagogues in the whole country. ^[54]
• Wales before Christianity had a Celtic religion. Wales retained Celtic aspects^{[ clarification needed ]} in the church during the Middle Ages.

Language

Further information: Welsh-speaking population

The 2011 census collected information about English and Welsh language proficiency. In 2011, 2.9 million (97%) of residents age three and over spoke English or Welsh. In a further 18,000 households, at least one adult spoke English or Welsh. In 22,000 households, no resident spoke either language. There were 562,000 (19%) residents over age three proficient in at least speaking the Welsh language. This was a reduction of approximately two per cent compared to 2001, though the method of analysis differed between the two censuses. There was also a two per cent increase in those over three years of age who had no Welsh language skills. ^[36]

The proportion of respondents in the 2011 census who said they could speak Welsh.

Marriage and civil partnership

In 2011, those who were married were still the largest marriage or civil partnership status group in Wales for residents aged 16 and over, though since 2001 this group has decreased by 37,000 (over 5%). In contrast, single people (i.e. those who have never married or been part of a same sex partnership), have increased by 190,000 (6%) in the ten-year period. Civil partnerships, which were given legal status in 2005, appear for the first time in the census results. The number of widows, widowers and surviving partners is 20,000 lower than in 2001. The final groups, relating to separation and divorce or legal dissolution of civil partnerships, have both seen an increase in both numerical and relative terms since 2001. ^[36]

Military staff and veterans

Main article: Armed forces in Wales

Out of all the armed services, the Army has the largest presence in Wales, with over 1,400 personnel based there. As of 2019, there were 3,230 military and civilian personnel based in Wales. ^[56]

In the 2021 census, around 115,000 people in Wales reported that they had previously served in the armed forces, around 4.5% of usual residents in Wales aged 16 years or older. ^[57]

Miscellaneous data

• Population density (2006): 143 people per square kilometre ^[58]
• Fertility rate: 1.90 (2007) ^[59]
• In 2010, 58% of births were outside marriage in Wales. ^[60] Currently^{[ when? ]}, Wales and Scotland are the only countries of the United Kingdom where the majority of births are outside of marriage (51.3% of births in Scotland in 2012 were outside of marriage). ^[61] Wales (along with Scotland) also had the highest death rate (10.9 per thousand) in 2005. ^[62]
