This paper reports the results of a sample survey of incidence rates of cerebral stroke in the P.R. China. It was found that the incidence rate for cerebral stroke in 1986 was 109.95 per 100,000 people. The adjusted incidence rate by composition of population of the cities and the rural areas in the P.R. China in 1986 was 110.58/100,000. The age-adjusted incidence rate by 1982 population of China was 84.07/100,000. The age-adjusted incidence using the world standard population was 115.87/100,000. The features of distribution of stroke incidence rates in the place, time, and population were analysed in the paper.
