“…Components of social class have been shown to provide certain subgroups with different kinds of mortality experience; education has been researched by Kitagawa and Hauser (1968), McGirr (1976b), and Upchurch (1962), occupation by Dom (1959), Sauer and Parke (1974), and Tuckman et al (1965), and economic status by Altenderfer (1947), Schwirian and Lagreca (1971), and Yeracaris (1955). Other differen tials studied for the social inequality of mortality include urbanrural residency (Arriga, 1967); Glass, 1964;Wiehl, 1948), marital status (Berkson, 1962;Nam, 1968;Young et al, 1970), sex (Geerken and Gove, 1974;Gove, 1973;Price, 1954), health and medical care and facili ties (McGirr, 1976a;Stockwell, 1961), housing and household charac teristics (Coombs, 1941;Ellis, 1957), race (Howard and Holman, 1970;Sutton, 1971), and ethnicity (Schwirian and Lagreca, 1971). But a host of problems remain in mortality analyses.…”
