NOTE: All thresholds are after-tax unless otherwise noted; dates in parentheses are the year for which the threshold was developed; all amounts are expressed in constant 1992 dollars using the CPI-U (except the second one, as noted).
a Renwick threshold calculated as weighted average of thresholds for two-adult/two-child families with one earner and two earners. (Weighting assumes that 75% of two-adult/two-child families have two earners and that one-third of those pay for day care.)
b Calculated as one-half average (rather than median) expenditures of four-person consumer units.
c Survey question did not specify whether respondents were to indicate minimum income level before or after-taxes.
d Survey question asked respondents to indicate minimum income level before-taxes.
