Have you ever wondered how similar or different two states are? The State Similarity Index attempts to quantify how similar states are to each other relative to other states. The index is a statistically-based way to measure this. The index weights equally five major aspects of states: their demographics, culture, politics, infrastructure, and geography. The research combines 1,000 different data points to reach the conclusions.
