The largest family size category became "nine persons or more." The poverty guideline figures are not the figures the Census Bureau uses to calculate the number of poor persons.
The figures that the Census Bureau uses are the poverty thresholds.
There are two basic versions of the federal poverty measure: the poverty thresholds (which are the primary version); and the poverty guidelines.
The Census Bureau issues the poverty thresholds, which are generally used for statistical purposes—for example, to estimate the number of people in poverty nationwide each year and classify them by type of residence, race, and other social, economic, and demographic characteristics.
The disparity of expenditures is much less than the disparity of income.
