Probability Sample Files (PSF)

The PSF is a subset of eHRAF World Cultures and a special kind of random sample called a stratified random sample. For the PSF sample the world was divided into 60 culture areas (strata) and one case from each area was randomly chosen from a list of societies that met certain data quality control criteria (such as whether one of the ethnographers stayed for more than a year and claimed to be fluent in the native language).

All 60 of the PSF cases are included in the paper, microfiche, and online versions of the HRAF Collection of Ethnography. For the rules used in selecting the sample cases, see Naroll, Raoul. 1967. The proposed HRAF Probability Sample. Behavior Science Notes (now Cross-Cultural Research) 2: 70-80.

The 60 culture sample too large for your purposes? Randomly select a smaller number of societies (at least 20 are recommended).

In eHRAF World Cultures a search query can be refined by sample and subsistence type.  This is done after a search in the culture results page.

60 Culture PSF in Excel Format and PDF Format:

Classification of the Major Form of Subsistence  (for the cultures in eHRAF World Cultures)

Key
Hunter-gatherers  – also called foragers; depend almost entirely (86% or more) on hunting, fishing, and gathering for subsistence
Primarily Hunter-gatherers — also called foragers; depend mostly (56% percent or more) hunting, fishing, and gathering for subsistence
Pastoralists depend mostly (56% or more) on herding or pastoralism.
Horticulturalists –depend mostly (56% or more) on simple agriculture (extensive or horticulture)
Intensive agriculturalists —depend mostly (56% or more) on intensive agriculture (with more or less permanent field cultivation and/or irrigation)
Pastoral/agriculturalists —not any of the above and pastoralism and agriculture/horticulture combined contribute at least 76% or more to the economy.
Other Subsistence Combination (includes other combinations of hunting, fishing, gathering, pastoralism, and horticulture or intensive agriculture).
Commercial economy—at the time of description people did not make their living mostly by hunting, fishing, gathering, pastoralism or agriculture, but mostly made their living by working for wages, selling products, or in business.
