The Economic Policy Insitute's Family Budget Calculator "measures the income a family needs in order to attain a secure yet modest living standard by estimating community-specific costs of housing, food, child care, transportation, health care, other necessities, and taxes. The budgets, updated for 2013, are calculated for 615 U.S. communities and six family types (either one or two parents with one, two, or three children).
"As compared with official poverty thresholds such as the federal poverty line and Supplemental Poverty Measure, EPI’s family budgets offer a higher degree of geographic customization and provide a more accurate measure of economic security. In all cases, they show families need more than twice the amount of the federal poverty line to get by."
The calculator shows numbers for specific areas, including Eugene-Springfield.
