Assumptions underlying use of survival ratios in population studies have been examined repeatedly, but some uncertainty remains as to the best ratio for specific problems and as to the advisability of attempting to correct ratios for variations in mortality, in racial or ethnic composition, in rural-urban residence, and in other categories or classifications. In separate research projects,' and in collaboration, the aitzth,ors and their colleagues 2 used survival ratios to estimate migration for various areas and residence groups and in. computing replacement ratios for rural-farm males of working age. In this article the authors report results of their explorations during the course of this work.
