The Immigration Policy Project of the National Conference for State Legislatures released a summary of state studies on the fiscal impact of immigrants. The data reflects the financial contributions made by foreign nationals to states. According to the summary:
Several states and organizations have conducted studies on the fiscal and economic impacts of immigrants or on specific immigration laws. Because of the complexity of researching unauthorized immigrants, studies are limited in scope and size. Some address all foreign-born, while others address only illegal immigrants or Hispanic residents (without addressing citizenship or immigration status). Estimates of tax revenues typically focus on income, sales and property tax. Some studies examine health, education and law enforcement costs, while others focus only on education. A few go beyond traditional assessment of taxes paid versus services used to examine the multiplier effects of immigrants in the labor force and economy.
