ABSTRACT
In the survey of cross-cultural studies, the writer found only 50 percent which attempted to maintain equivalence for three or more sampling categories across cultures, the most common categories being age, sex, education, and urban-rural background. Cross-cultural research is extremely expensive involving as it does more personnel, travel, and time than other kinds of research. Apart from the urban-rural sampling, the categories readers chose to ensure that comparison could be made across cultures were age, sex, education, intensity of religious belief, and occupational structure. The countries selected were India, Indonesia, Iran, Italy (Sardinia), USA, and Yugoslavia. Thus, the time of the study is generally one of pre-crisis in all countries, so that the 1963 data should not be too out of touch. Selection of countries is sometimes dictated by political factors, but more often simply by the availability of funding.
