What does the ONS Longitudinal Study tell us about the quality of NHS registration data? The aim of this research project was to assess the quality of NHS registration data by comparing location of residence between the census with that of the NHS registration system. By using the Longitudinal Study (LS) data matched to the NHS data we have assessed: the number of people that have a different location of residence in the census compared to the NHS data; the time lag between the location of residence being amended on the NHS data to match the location of residence on the census; migration indicators from the census and, the characteristics of these people. Data based on NHS registration activity is a key source feeding into current and potential new population statistics systems. Within the current population statistics system, these data are used: to estimate the migration of people within the UK; to allocate international migrants to local authority level; and to produce population estimates for lower level geographies. The Beyond 2011 Programme has been established to carry out research on the options for a new population statistics system. One likely option is greater use of administrative data, and NHS registration data would play a key part in this. This analysis has the potential to identify certain population groups that may be under represented in the NHS data to estimate the population, so that statistical methods and research can be undertaken to address this. This is a continuation of earlier work produced using data from the 2001 Census and published in Population Trends 141.
