Abstract:

Address listing plays a key role in the design of contemporary census enumeration and in quality assessment by matching to administrative data. Further, the recording of individual addresses underpins the delivery of healthcare services and is central to the potential replacement of a conventional census by use of linked administrative records. Little is currently understood about the accuracy of address recording on administrative systems - and hence their potential effectiveness in capturing the entire population - across different population subgroups. This paper describes an initial investigation using the unique Northern Ireland Longitudinal Study (NILS). NILS is a 28% sample of the Northern Ireland population, matched between the census and health register maintained by the HSC Business Service Organization (BSO), equivalent to the National Health Service register. Anonymised unique property reference numbers, linked from the LPS database, have been matched between the 2001 census and corresponding health register for NILS members, allowing the consistency of addressing in the two sources to be investigated. This analysis explores household and neighbourhood determinants of address inaccuracy, including the geographical distances between mismatched addresses for the same individual, and reveals patterns of address quality in terms of individual characteristics, household composition and dwelling type.
