ABSTRACT
This chapter outlines some of the features of population movement in the urban system, concentrating on the characteristics of differential migration. It shows that, like Greater London, Million City labour markets as a whole were losing relatively low proportions of their total migration outflow within the managerial and professional groups. The chapter explains that the managerial group exceeds the skilled workers in terms of absolute net out-migration from the urban system. An analysis of the relationship between rates of net migration change and rateable value increases at the Metropolitan Economic Labour Area (MELA) scale yields relatively high correlation coefficients. The migration mechanism itself should be seen as a process rather than a set of independent, unrelated actions. As for age-structure data, there are no details of gross migration flows by socio-economic group for MELAs, or the pre-1974 local authorities which constitute their building blocks.
