States have enormous responsibilities. They must not only meet their citizens’ needs on a wide range of issues—from education to healthcare to housing and job security—but also manage enormous budgets, often larger than most countries. How they do it, and do it well, is an important question. And for those that are succeeding, how are they succeeding? Measuring performance and developing a fact base for decision making is critically important for states to understand what they’re doing well, where they need to improve, and what their residents value most.
