Across the United States, regional culture greatly influences the friendliness of its people. The sense of welcome, courtesy, and civic engagement may differ from state to state, shaping the experiences of visitors, new residents, and locals alike. Our "Friendliest States" ranking, derived from the Politeness Index, offers a comprehensive view of the U.S. states with the kindest and most sociable populations. This ranking is based on the voting of 2.5 million people on Big 7 Travel, who shared their personal experiences of friendly encounters, hospitality, and neighborly relations across the country.
