Property rate is the percent of the population with income
below the official poverty threshold, put at $16,036 for a
four-person family in 1996. The official poverty definition is
based on pretax money income only and does not include the
value of non cash benefits such as food stamps, Medicaid or public
housing. Note: Racial classifications change over time as
the Census Bureau collects data on Hispanics and Asians. We adjusted
the distribution to take into account the double counting
among blacks and Hispanics.
