This article reports the results of a survey of State Aid to Families with Dependent Children (AFDC) rules regarding the treatment of unrelated cohabitors in households containing AFDC units. We examine State treatment of cash and in-kind contributions by cohabitors and find that the AFDC grant is usually not affected in the cohabitor makes in-kind contributions toward food and shelter expenses of the household. However, the grant generally is reduced if the cohabitor contributes cash to the AFDC unit unless the cash is for shared household expenses. In addition, a few States have specific policies toward cohabitors that are not based on initial evidence of cohabitor contributions.
