Abstract:

There is considerable evidence that official population statistics are inaccurate at local authority level, too infrequent and out of date. The most consequential of these problems is that of under-enumeration, with certain areas in England disproportionately affected by under-counting, and therefore under-funding. Further, statistical boundaries are inflexible and lack the geographical granularity needed at small area level to plan and deliver services. This paper looks at how using local administrative data can overcome these problems by innovatively linking these datasets together by the address field as the common denominator. The GP Register is treated as the most comprehensive of these datasets to use as a base to which other datasets are cross-referenced to. Effectively, each address in an area is the basic unit of analysis. This allows an authority to profile their population in socio-economic, health or education contexts to any spatial extent. The project aims to refine and evaluate the approach and assess its suitability at larger scales. The geo-referenced population output will be applied to measuring local deprivation to any non-standard unit using multivariate techniques. The topic is relevant to policy, with a recent Treasury Sub-Committee hearing reinforcing the issues with current population statistics and recommending utilising administrative data for future Censuses.
