Congressional Budget Office Study

During 2007, the nonpartisan Congressional Budget Office reviewed 29 reports published over 15 years on the impact of unauthorized immigrants on the budgets of state and local governments. While cautioning that the reports are not a suitable basis for developing an aggregate national effect across all states, they concluded that:

• State and local governments incur costs for providing services to unauthorized immigrants and have limited options for avoiding or minimizing those costs;
• The amount that state and local governments spend on services for unauthorized immigrants represents a small percentage of the total amount spent by those governments to provide such services to residents in their jurisdictions;
• The tax revenues that unauthorized immigrants generate for state and local governments do not offset the total cost of services provided to those immigrants, although the impact is most likely modest; and
• Federal aid programs offer resources to state and local governments that provide services to unauthorized immigrants, but those funds do not fully cover the costs incurred by those governments.
