The decline of mortality from stroke observed in some countries may result from a fall in incidence or a decrease in case‐fatality rates from stroke. The present study was conducted to evaluate the role of geographical parameters, comparing an urban and a rural population in Burgundy, France to look for differences in risk factor distribution. The study was a prospective, and complete case‐ascertainment in a population‐based survey. It was conducted on a well‐defined population‐based survey in a rural town (Avallon 8900 subjects) and an urban town (Dijon 140,000 subjects) in the area of Burgundy (France), from 1989 through 1993. All first‐ever stroke events occurring in these two populations, whatever the age, were registered by a special six‐level case‐registration system. 1118 strokes cases were identified, 986 in Dijon and 132 in Avallon. In the rural area (Avallon), the incidence and case‐fatality rates at 28 days were higher than those of Dijon. The higher incidence rate in Avallon may be explained by the fact that there was a higher rate of non‐treated hypertension. The higher case‐fatality rate in Avallon may be explained by a higher rate of hemorrhagic strokes and of comatous patients. Rural and urban populations perhaps have not the same risk factors for stroke. The differences observed in incidence and case‐fatality rates should lead to a survey on the risk factors and their diagnosis and treatment between rural and urban populations.
