The extent of collection of information on migrant and asylum seeker status in routine health and social care data sources in England

While efforts to mainstream collection of ethnicity in routine health datasets have gathered pace since the Race Relations (Amendment) Act 2000, relatively little attention has focused on the capture of migrants, and data on asylum seekers and refugees are even more sparse. There is negligible coverage in the key datasets for primary and secondary care, and only a few of the new contract datasets to support the National Service Frameworks accord importance to the migrant population. Some of the communicable disease data collections record country of birth, but its incompleteness is a drawback. Given the growing size of the non-UK-born population and the accumulating evidence on the health and health care needs of the migrant population, country of birth merits a place alongside other access variables such as age, sex, ethnicity, socioeconomic status and place of residence in routine data collection. While record linkage studies offer some scope, and there is currently a focus on obtaining improved migration statistics in the forthcoming census and other data flows, health and social care sources remain a neglected area.
