Reid A, Harding S. Trends in deprivation and mortality using the Longitudinal Study. Health Statistics Quarterly 2000; 05 (Spring):

This paper examines trends in regional mortality using a deprivation index based on individual characteristics. Generally mortality levels and the proportions classified as deprived were lowest in the South. In 1991-97, the death rate of men aged 26-64 classified as most deprived was more than twice that of the least deprived in six of the nine regions. The level of inequality in a region (as measured by the ratio of death rate of most deprived to that of the least deprived) was not highest in the high mortality regions or lowest in the low mortality regions. Though not always statistically significant there was a consistent pattern of widening inequality and death rates between the 1980s and 1990s in most of the regions among women and men of working ages and older men. The increase in inequality in mortality was due to the consistent declines in the death rates of those least deprived and little or no decline in the death rates of those most deprived.
