Simple Random Sample (SRS) (eHRAF World Cultures)

In a Simple Random Sample (SRS), all cases from a list have an equal chance of being chosen. As of September 1, 2016 there are 28 societies chosen by simple random sampling from a list of over 2,000 cultures. In contrast to the Probability Sample Files, the list is not stratified by geographical criteria and a culture does not have to have a certain amount of pages of ethnography. However, we only include a culture if it has at least the equivalent of one comprehensive ethnography.

For eHRAF World Cultures, the SRS is randomly sampled from a list of cultures compiled from 8 different cross-cultural samples (Ember et al. 1992. Computerized Concordance of Cross-Cultural Samples. New Haven: Human Relations Area Files).

This table shows all the cultures in the Simple Random Sample:
