The current official poverty measure was developed in the early 1960s, and only a few minor changes  have been implemented since it was first adopted in 1965 (Orshansky, 1963, 1965a, 1965b; Fisher, 1992). This measure consists of a set of thresholds for families of different size and composition that are compared to a resource measure to determine a family’s poverty status. At the time they were developed, the official poverty thresholds represented the cost of a minimum diet multiplied by three (to allow for expenditures on other goods and services). Family resources were defined for this measure as before - tax money income.
