The Most Similar States to Kentucky

Kentucky similar states MAP

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. Each aspect was roughly balanced evenly between quantity/percentage and quality/type. See this post for a full explanation: State Similarity Index

Kentucky is a Southeastern state. The five most similar states all have temperate climates and their forests are generally full of deciduous broadleaf trees. In addition, four of the five are landlocked. These states tend to be quite religious as well. They also have many guns per capita. These states have favored the Republican Party in recent years. Furthermore, the standard of living is not especially high in these states. They generally have high rates of poverty.
