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).

Excel format: A comprehensive list of the 28 culture names from the Simple Random Sample (SRS) currently included in the eHRAF World Cultures database. The excel format also includes sequence and installment numbers, OWC codes, region coverage (including subregions), date coverage (beginning and ending dates for cultural materials), subsistence and the PSF sample type. The sequence numbers for each culture name make the excel table  useful for generating a random sample from eHRAF. Visit the Cross-Cultural Research section to learn more about random sampling.
