Some mortality characteristics of Japanese immigrants and their descendants living in the city of S. Paulo, Brazil, are analysed. Comparison between these characteristics and those among the populations of Japan and the city of S. Paulo has been made. The Japanese immigrants and their descendants have an intermediate pattern of mortality ranking between the pattern of Japan and the S. Paulo one, being closer to the former. The infant mortality rate among the Japanese born in S. Paulo is much lower than the S. Paulo rate. The death rate for vascular lesions affecting the Central Nervous System is higher in Japan. On the other hand, the death rate for diseases of the heart (except rheumatic heart disease) is much higher in S. Paulo. The association of a low death rate for diseases of the heart with a high death rate for vascular lesions affecting the Central Nervous System is observed. The Japanese immigrants tend to occupy an intermediate mortality level for both causes of death here mentioned. These results suggest that the environmental factors play an important role in the immigrants' pattern of mortality.
