Abstract: | Since 1989, federal law requires states to have presumptive child support guidelines and review them using economic data on child-rearing costs at least once every 4 years. This article reviews the child support guidelines models adopted by states, how they relate to estimates of child-rearing expenditures, the extent that states are updating their guidelines, and some of the more controversial guidelines provisions (i.e., adjustments for shared-parenting time, additional dependent children, and low-income nonresidential parents). We find that many states are not updating their core formulas and schedules. As a result, several state guidelines produce support award amounts that are below the costs of raising children. |
