Contemporary international migration flows into European cities are no
w more diverse than used to be the case. The movement of less-skilled
labour migrants has been replaced by the circulation of high-skill exe
cutives and specialist personnel involved in transnational corporation
s and in the financial services and other sectors affected by economic
globalisation. To these are added other new service migrants and incr
eased hows of students and independent young people. As a result, worl
d cities are now witnessing the emergence of important categories of n
on-racialised international migrant groups. This paper considers wheth
er such groups form distinctive residential concentrations in Greater
London and uses the limited aggregate data available from the census t
o establish a general view of the geography of developed world migrant
s. There are important implications for urban theory and for discussio
ns of urban ethnicity.
