The Standard Cross-Cultural Sample consists of 186 anthropologically-described societies that were chosen by the creators, Murdock and Whlte (1969). The sample tried to minimize cultural relatedness and so only one society was chosen from a culture area. Each society is pinpointed in time and space. Researchers coding variables for this sample are expected to adhere to the specified time and place focus . To facilitate research for those wanting to code their own variables using eHRAF World Cultures for this sample, the HRAF staff have flagged those documents that in HRAF’s judgment provide an appropriate match. Later documents may also provide evidence of prior time periods, but they should be examined with caution.
