The standardised mortality ratios (SMRs) for coronary heart disease (CHD) werecalculated for all cities, Large Burghs, Small Burghs and landward areas of Scotland for the periods 1959–63 and 1969–73; for 1979–83, the SMRs were calculated at District level only, due to changes in local government boundaries. Communities with SMRs which were significantly high or low were noted, as were those with SMRs which were above 125 or below 75 but not significant. The geographical locations of the communities and their mortality records for CHD were presented in a series of maps. During both 1959–63 and 1969–73, high SMRs for CHD predominated in westcentral and south-western Scotland, especially around Glasgow, and in several Small Burghs in the south of the country; by contrast, communities with significantly low SMRs were located predominantly in the east and north-east. This gradient of mortality persisted durign 1979–83 in the Districts.
