Benjamin Disraeli, the famous nineteenth century prime minister, said, "London is not a city, - it is a nation." Today this is an understatementLondon, with its vast range of different ethnic groups, is a world. Certainly, London is the most culturally diverse city in the world. The city was founded by the Romans and since then new arrivals have constantly added to its character and prosperity. Within 10 years 40% of Londoners will be from ethnic minority groups, including the growing number of Londoners of mixed ethnic origin, but most of them will have been born in Britain. Children of Caribbean-Chinese marriages will go to school with children of Russian-Irish couples. None of them will be English but all of them will be Londoners. Most of Britain's ethnic minority residents live in the capital, speaking over 300 languages. Nearly all of the African population and many of the Caribbean population of Britain live in London (83% and 58% respectively)39% of the Chinese population of Britain and 36% of the Asian population of Britain live in London. The largest migrant community is from the Irish Republic with 256,000 people, 3.8% of the total population of London. There are an estimated 330,000 refugees and asylum seekers living in London, with most recent arrivals coming from Eastern Europe, North Africa and Kurdistan. Young people, in particular, are skilled at dealing with a large number of different and hybrid cultures. They themselves often have several different ethnic identities since their parents and grandparents may come from several different backgrounds and their friends and partners do also. They are "skilled cross-cultural travelers" without leaving their home-town.
