In Scenario 1, for each state, we assumed that the father on the case worked for 4.33 weeks and each week he earned half of the median weekly earnings of male workers in that state in 2018. Median weekly earnings by state and sex are publicly available from the Bureau of Labor Statistics (BLS, 2019). Fathers’ monthly gross incomes for each scenario are shown in Appendix B Tables 1 and 2 for all 50 states and the median state. For the median state, the father’s income in Scenario 1 was $2,089 per month, or about $12 per hour and about 200 percent of the federal poverty level for a single person household in 2019. This income level approximates the OECD definition of low pay, which refers to individuals earning less than two-thirds of median earnings (OECD, 2019).7F8 This income level also allows us to examine order amounts for fathers that are low-income but unlikely to qualify for a low-income adjustment, since adjustments are typically targeted toward those with incomes closer to 100 percent of the federal poverty level.
