title: Research implications of improvements in access to the ONS Longitudinal Study.
abstract: In this article we outline significant changes in the way the ONS Longitudinal Study data are stored, accessed and analysed. The data were held previously on mainframe computers. Recent technological changes have made it possible to introduce PC-based systems without compromising confidentiality. The advantages of this new computing environment are illustrated with recent findings on geographic inequalities in health.
