abstract="English health services require reliable population denominators to guide equitable sharing of resources. 2001 census counts for England are compared with the corresponding 2000-base projections for 2001, both at the national scale and for individual local authorities and also with corresponding 1996-base projections. Comparison is made with the 2001 census for Northern Ireland. National patterns of variation predominantly may be explained by mis-estimation of international out-migration, but local patterns of variation may be more specifically related to mis-estimation of international in-migration. This suggests two distinct patterns of systematic error in official UK migration statistics between 1991 and 2001.<p />",
