Abstract
Mortality data for ischaemic heart disease and lung‐bronchus cancer in the 29 metropolitan boroughs of London and the 37 electoral wards of Glasgow are standardised for age and sex relative to an all‐U.K. norm. The standardised mortality ratios (S.M.R.) obtained, when expressed in map form, reveal marked spatial inequalities. A relationship with social class and concomitant housing and living standards is indicated.
