Arizona's Goldwater Institute has released a study that examines poverty at a state-by-state level. The key finding: "Using data from the U.S. Census Bureau, the pages that follow demonstrate that low-tax and -spending states enjoyed sizable decreases in poverty rates during the 1990s. High-tax and -spending states, meanwhile, suffered increases in poverty rates."

To complement this study, Goldwater has also unveiled an interactive map from which you can easily view the progress your state has made in reducing poverty. D.C. gets an "F."

The study and map should provide good rebuttals for those who argue that what's need to reduce poverty is big government, not low-tax free enterprise policies.
