[5] Kroeber, 1925_a_, p. 883. The breakdown has been changed somewhat to accommodate boundary changes; the total remains the same. The population density, according to Kroeber's figures, is 1.6 persons per sq. mi. [6] Cook, 1956. The breakdown has been changed somewhat to accommodate boundary changes; the total remains the same. The population density, according to Cook's figures, is 4.6 persons per sq. mi. The corpus of information provided by the methods outlined above would be useful in two ways. First, it would clarify our definitions of the economic factors in the lives of hunter-gatherers. Functional hypotheses which postulate dependence of social factors on economy would be subject to objective, quantitative tests of their validity.
