Address information from administrative sources such as the healthcare system is significant on three counts. Firstly, it can be used to contact individuals for healthcare interventions and might then be used in follow-up monitoring. Secondly, it is currently used for statistical purposes such as migration and population estimation as well as being used to update UK longitudinal studies. Thirdly, its prospective importance might increase given possible moves to supplementing (or replacing) traditional censuses in the UK with administrative data. For these reasons, it is important to know more about the accuracy of data of this type. The paper contributes to this aim by analysing inaccuracies in address information provided by the Business Service Organisation (BSO) in Northern Ireland in comparison with the ‘gold standard’ of the 2001 Census. The work is undertaken in the framework of the Northern Ireland Longitudinal Study (NILS). It explores the demographic, social and economic conditions associated with mismatches between the BSO and the census; it considers the geographical patterning of these errors; and it outlines the factors that underlie lags in updating address information through the BSO.
