WITH a pub, a church green and a golf course at its centre, Bushey, a settlement of 26,000 people in Hertfordshire, is a typical wealthy commuter town. Yet its residents illustrate both an old pattern of migration and a new one. Indians, who have long been concentrated in north-west London, are moving out. Between 2001 and 2011 the number of Hindus in Bushey has increased by 70%, albeit from a tiny base: 4% of the population of Hertsmere, the local authority, is now Indian. Even as the Indian population of some inner-London boroughs shrinks, it is growing quickly in metroland (see map). Hindus now account for a fifth of the population in Stanmore, a suburb a few miles to the south of Bushey. When Gujarati-speaking Asians were expelled from Uganda in 1972 by Idi Amin, one of the designated "red-star zones" for receiving them was Harrow, an outer London borough. As the immigrants and their children have become more prosperous they have moved farther north, attracted by good schools and spacious houses. The same is happening elsewhere. Many of the Ugandan Asians who settled in Leicester in the 1970s, have moved to Oadby, a wealthy suburb that is now 33% Indian. Trevor Phillips, former chair of the Equality and Human Rights Commission, identifies two broad types of immigrant in Britain: "shipwrecks" and "settlers." Both integrate, but in different ways. Afro-Caribbeans, a "shipwrecked" group, arrived with little social capital. They often became stuck in poor areas and settled down with the natives. Settlers, by contrast, rarely marry outside their own group. They are upwardly mobile and move to wealthy suburbs. But the movement of Indians around the fringes of London also points to a distinctive relationship between two minority groups. Since the 1960s the "north-west passage" above London has been largely Jewish. Many Indians worked for Jewish firms when they arrived, or bought local businesses from them. One result was the creation of the Indian-Jewish Association, a society that holds networking events and arranges cross-cultural activities. And an affinity between the two groups - built on the shared values of hard work and an emphasis on traditional family and religious ties - means that they have moved into the same neighbourhoods. "We copied a lot of things from Jews," says Lord Popat, a Conservative peer who arrived from Uganda in 1971. As the Jews moved on, we more or less followed them.
