The starting point for any discussion pertaining to multiculturalism and post-multiculturalism is the extent to which any culturally heterogeneous society is indeed in need of a particular paradigm for governing and negotiating cultural claims associated with minority groups. As many have argued the move towards a post-multiculturalism has its foundations in the changing nature of global human mobility, the marginalised socioeconomic position of many migrant communities in Western cities, and the heightened securitised debate about particular minority groups. This chapter reports the global perspectives highlighting these difficulties in Europe, UK, North America, South America, Australia and New Zealand are indicative of palpable negative shift in public attitudes in these societies towards migration, cultural and religious diversity. From this perspective post-multiculturalism is, first, the public repudiation of multiculturalism by elite public figures and policymakers, of which there are numerous examples from the mid-2000s onwards in Australia, Europe and to a lesser extent the US many depicted in contributions to this volume.
