Selective sorting and the stayers left behind: what does this mean for changing ethnic health gradients in England?

A number of studies explore the contribution of selective migration to health gradients, particularly in the UK. Using longitudinal data, these studies find that through migration or residential mobility (however defined), a sorting process can differently distribute (un)healthy groups of people between areas, and that over time this can widen health gradients. The mobility of these differently healthy groups is therefore of central importance. However, the immobile groups and their possible contribution to changing health gradients receive less specific coverage in the literature. Further, no work has investigated ethnic variations in either the mobile or immobile groups, or their influence on changing ethnic health gradients. This paper asks whether ‘stayers’ influence health gradients, and whether the relationship between ‘staying’ and health varies by ethnic group. It is likely that propensities for immobility may be as important as propensities for mobility in respect of the influence on changing health gradients. Starting with the premise that selective sorting between area-types through migration can widen health gradients, as various work has demonstrated, this paper will explore how socio-demographic attributes, health and experience of deprivation help explain propensity to migrate for different ethnic groups in England. Using data from the Office for National Statistics Longitudinal Study in 1991, 2001 and 2011, binary logistic regression models will be used to illustrate the increased likelihood of immobility for certain population subgroups which may exacerbate health gradients already widened by selective migration.
