Abstract
Objective To compare all cause mortality between the north and south of England over four decades. Design Population wide comparative observational study of mortality. Setting Five northernmost and four southernmost English government office regions. Population All residents in each year from 1965 to 2008. Main outcome measures Death rate ratios of north over south England by age band and sex, and northern excess mortality (percentage of excess deaths in north compared with south, adjusted for age and sex and examined for annual trends, using Poisson regression). Results During 1965 to 2008 the northern excess mortality remained substantial, at an average of 13.8% (95% confidence interval 13.7% to 13.9%). This geographical inequality was significantly larger for males than for females (14.9%, 14.7% to 15.0% v 12.7%, 12.6% to 12.9%, PConclusion Inequalities in all cause mortality in the north-south divide were severe and persistent over the four decades from 1965 to 2008. Males were affected more than females, and the variation across age groups was substantial. The increase in this inequality from 2000 to 2008 was notable and occurred despite the public policy emphasis in England over this period on reducing inequalities in health.
