From 1951–91, the British population born outside the UK almost doubled, and, as a percentage of the total population, increased from 4.3 to 7.3 per cent. By 2011, the population born outside the UK had increased to 13.4 per cent. Traditionally, the largest non-UK component in the population has been Irish, but this began to stabilize and recede from the 1960s. Significant migrations from Poland, Germany and Italy occurred post World War II. Significant inflows from the Caribbean peaked in the 1950s and the Indian population doubled from 1961–71. The numbers of Bangladeshis doubled from 1971–81, while political instability provoked specific spikes of immigration for Ugandan Asians and Greek Cypriots. Most of the major non-UK populations are concentrated in urban areas, and mainly in England. Bangladeshi and Caribbean residence is overwhelmingly in London and Birmingham. Indians and Pakistanis are also strongly represented in other urban centres in the Midlands, Lancashire and Yorkshire. The most dispersed ethnicity is the Chinese.
