NHS registration data has many uses in ONS. This presentation addresses questions of quality and use of NHS registration data: Who is not registered at the same address on NHS records and the Census? How long is the registration lag for different demographic groups? Who never registers? Are some areas worse than others for discrepancies? Should we be worried about students, men or migrants? Are registration 'trends' changing?
Analysis linked the Longitudinal Study - the longitudinally linked Census data representing 1% of the population - with NHS registration data and postings information which shows ongoing changes to administrative data. It looks at two cohorts, from 2001 Census and 2011 Census, and shows how many people were at the same address in the Census and their NHS registration. Of those who weren't, how long it took to register at the Census address. The 2001 cohort is then checked again at the 2011 Census.
