Within the United States, a 2007 study conducted through the University of Baltimore estimates that 50% of all child support arrears are owed to the government to reimburse welfare expenses. Half of U.S. states pass along none of the child support they collect to low-income families receiving welfare and other assistance, instead reimbursing themselves and the federal government. Most of the rest only pass along $50.00 per month. The bipartisan 2006 Deficit Reduction Act and other measures have sought to reduce the amount of money claimed by the government and to ensure that more funds are accessible by children and families, noting that more obligors (paying parents) are willing to pay child support when their children directly benefit from payments.
