Public opinion estimates are produced using a statistical model based on national survey data gathered between 2008 and 2016 by the Yale Program on Climate Change Communication and the George Mason Center for Climate Change Communication. The Global Warming’s Six Americas segments are determined using 36 survey items that include questions about climate change beliefs, risk perceptions, behaviors, and policy support. “Metro” areas include both metropolitan and micropolitan areas as defined by the U.S. Census Bureau.
