Demographics

See also: Demographics of the Republic of Ireland and Demography of the United Kingdom

The demographics of the British Isles today are characterised by a generally high density of population in England, which accounts for almost 80% of the total population of the islands. In elsewhere on Great Britain and on Ireland, high density of population is limited to areas around, or close to, a few large cities. The largest urban area by far is the London metropolitan area with 12–14 million inhabitants. Other major populations centres include Greater Manchester Urban Area (2.5 million), West Midlands conurbation (2.3 million), West Yorkshire Urban Area (2.1 million) in England, Greater Glasgow (1.7 million) in Scotland and Greater Dublin Area (1.6 million) in Ireland.

The population of England rose rapidly during the 19th and 20th centuries whereas the populations of Scotland and Wales have shown little increase during the 20th century, with the population of Scotland remaining unchanged since 1951. Ireland for most of its history comprised a population proportionate to its land area (about one third of the total population). However, since the Great Irish Famine, the population of Ireland has fallen to less than one tenth of the population of the British Isles. The famine, which caused a century-long population decline, drastically reduced the Irish population and permanently altered the demographic make-up of the British Isles. On a global scale, this disaster led to the creation of an Irish diaspora that numbers fifteen times the current population of the island.

The linguistic heritage of the British Isles is rich, with twelve languages from six groups across four branches of the Indo-European family. The Insular Celtic languages of the Goidelic sub-group (Irish, Manx and Scottish Gaelic) and the Brythonic sub-group (Cornish, Welsh and Breton, spoken in north-western France) are the only remaining Celtic languages—the last of their continental relations becoming extinct before the 7th century. The Norman languages of Guernésiais, Jèrriais and Sarkese spoken in the Channel Islands are similar to French. A cant, called Shelta, is a language spoken by Irish Travellers, often as a means to conceal meaning from those outside the group. However, English, sometimes in the form of Scots, is the dominant language, with few monoglots remaining in the other languages of the region. The Norn language of Orkney and Shetland became extinct around 1880.
