This is the first social history to explore experiences of British emigrants from the peak years of the 1960s to the emigration resurgence of the turn of the twentieth century. It explores migrant experiences in Australia, Canada and New Zealand alongside other countries. The book charts the gradual reinvention of the 'British diaspora' from a postwar migration of austerity to a modern migration of prosperity. It offers a different way of writing migration history, based on life histories but exploring mentalities as well as experiences, against a setting of deep social and economic change. Key moments are the 1970s loss of Britons' privilege in Commonwealth destination countries, 'Thatcher's refugees' in the 1980s and shifting attitudes to cosmopolitanism and global citizenship by the 1990s. It charts a long process of change from the 1960s to patterns of discretionary and nomadic migration, which became more common practice from the end of the twentieth century. -- .
