The focus of this study was on an urban Muslim population in which race, nationality, caste, religion, and ethnic group were relatively consistent. During the years 1961-1964, author studied marriage registrations from three socioeconomic zones (high, middle, and lower class) in Karachi – the largest city in Pakistan.
Results showed that all marriages were arranged by families, and that the families’ interests were priorities in this process. A community’s marriage pool of eligible individuals determined mate selection. Author concluded that the lower the social class membership, the shorter the distance between registrants at the time of marriage, and vice versa. The findings were in accord with several other studies of same kind.
