Norwegian. They reside primarily on the Mediterranean coast and the Balearic islands, where many are retired or remote workers. Urbanisation Metropolitan areas Source: "Áreas urbanas +50", Ministry of Public Works and Transport (2013) Peoples The Spanish Constitution of 1978, in its second article, generically recognises contemporary entities—nationalities and regions'— within the context of the Spanish nation. Spain has been described as a de facto plurinational state. The identity of Spain rather accrues of an overlap of different territorial and ethnolinguistic identities than of a sole Spanish identity. In some cases some of the territorial identities may conflict with the dominant Spanish culture. Distinct traditional identities within Spain include the Basques, Catalans, Galicians, Andalusians and Valencians, although to some extent all of the 17 autonomous communities may claim a distinct local identity. It is this last feature of "shared identity" between the more local level or autonomous community and the Spanish level which makes the identity question in Spain complex and far from univocal. Minority groups Spain has a number of descendants of populations from former colonies, especially Latin America and North Africa. Smaller numbers of immigrants from several Sub-Saharan countries have recently been settling in Spain. There are also sizeable numbers of Asian immigrants, most of whom are of Middle Eastern, South Asian and Chinese origin. The single largest group of immigrants are European; represented by large numbers of Romanians, Britons, Germans, French and others. The arrival of the gitanos (Spanish for "gypsies"), a Romani people, began in the 16th century; estimates of the Spanish Roma population range from 750,000 to over one million.Recent Migration of Roma in Europe, A study by Mr. Claude Cahn and Professor Elspeth Guild , pp. 87–88 (09.2010 figures) There are also the mercheros (also called quinquis), a formerly nomadic minority group. Their origin is unclear. Historically, Sephardic Jews and Moriscos are the main minority groups originating in Spain and with a contribution to Spanish culture. The Spanish government is offering Spanish nationality to Sephardic Jews.
