The synthetic control method is an increasingly popular method for state policy evaluation. It provides quantitative support for case studies by creating a synthetic control region that simulates what the outcome path of a region would be if it did not undergo a particular policy intervention. In this report, we describe the method and provide simple step-by-step guidance for its application. We also explore pitfalls and concerns noted in the literature and other potential problems.
