Low income situation of individuals is determined using the Census Family Low Income After-Tax Measure (CFLIM-AT). Individuals are defined as having low income if their adjusted after-tax income falls below 50% of the total population median adjusted after-tax income. Adjusted after-tax income is derived by dividing census family income by the square root of the census family size and assigning this value to all persons in the census family. This adjustment distributes income among the members of the census family, and takes into account the economies of scale present in larger families, the increasing number of people living on their own and the decline in family size over time.
