Book excerpt: This study ranks the American states according to how their public policies affect individual freedoms in the economic, social, and personal spheres. Updating, expanding, and improving upon the three previous editions of Freedom in the 50 States, the 2016 edition examines state and local government intervention across a wide range of policy categories -- from tax burdens to court systems, from eminent domain laws to occupational licensing, and from homeschooling regulation to drug policy. Freedom in the 50 States remains the only index that measures both economic and personal freedoms.
