AIM: description of proportional mortality and death rates by Stroke in adult population (20 years of age or older) of São Paulo State, Brazil. METHODS: the deaths were obtained from the statistical official bureau; the population data were based in the Federal Census (1970, 1980 and 1991); all trends whose the slope was significantly greater than zero had a calculation of the decline per year. RESULTS: proportional mortality for Stroke decreased for males (M) (- 11.40%) and increased for females (F) (+7.58%); Stroke in all cardiovascular diseases showed increase in both sexes, +8.65% (M) and +3.12% (F); Stroke age-adjusted death rates declined 1.19% (M) per year and 1.76% (F) per year between 1970 and 1989; the ages whose decline was more important were those 60-years-old of age or older (M) and 40-years-old or older (F); the male/female sex ratio increased during the observed years (22% in 1970 to 45%) due to the change in the 50-59 age strata (36% in 1970 to 69% in 1989). CONCLUSION: the fall of the Stroke deaths rates could be due to increase in the detection and control of hypertension; other factors such as improve in death certification, decline of Chagasic myocarditis, new image-diagnostic tests and medical care had maybe only a secondary play in the decline of stroke mortality.
