Regional mortality differences in Britain, 1931-87: a two dimensional analysis.

In a recent analysis, Illsley, Le Grand & Mullings argued that, over the years 1931-87, regional inequalities in mortality in Britain effectively disappeared for most age groups. The present study reanalyses their data, breaking regional life tables down into their two major components, the level of survivorship, and the shape of the mortality curve. It is shown that whereas there has been a consistent decline in regional inequalities in the level of mortality, there has not been a comparable convergence in the shape of the mortality curves. These shape differences, implying premature adult mortality, are now the major source of variation among the regions.
