This document models the impact that work supports have on family income and expenses in two different ways. Both model a family with one parent and two children (a preschooler and a schoolage child) on the south side of Chicago (Cook County) Illinois. The document begins with a description of the work supports and child supports that are modeled, followed by an explanation of how and why the taxes and tax credits are treated differently in this document than in the Self-Sufficiency Standard itself. The first modeling section of this document shows the impact of work supports on monthly costs. The second modeling section in this document shows the impact of work supports on wage adequacy.
