Abstract
The article gives an overview of the work pursued by the medical geography research group in Trondheim. Activities are centred on a mortality data base containing more than 800,000 individual records for 1966–1985, with very flexible options for geographical manipulation. In addition, several other data bases are being used. References are made to research on regional variations and trends in cardiovascular disease and some cancers, and their potential causes, to comparisons between mortality patterns in Iceland and Norway, and to a thesis on aspects of the health and health care system in Poland.
