It is rarely necessary to use the entire eHRAF World Cultures for comparative studies. As long as a sample is representative of some well-defined universe of cultures, societies, or archaeological traditions, sampling a sub-set saves time and effort.
eHRAF World Cultures contains two samples that can be considered representative:
- Probability Sample Files (PSF)–60 largely preindustrial societies that meet certain data quality controls, one randomly chosen from each culture area. More.
- Simple Random Sample (SRS)–currently 28 societies randomly chosen from a compiled list of over 8 cross-cultural samples. More

eHRAF Archaeology also has a Simple Random Sample.
