This version of the Yale Climate Opinion Maps is based on data through the year 2016. Public opinion about global warming is an important influence on decision making about policies to reduce global warming or prepare for the impacts, but American opinions vary widely depending on where people live. So why would we rely on just one national number to understand public responses to climate change at the state and local levels?
Public opinion polling is generally done at the national level, because local level polling is very costly and time intensive. Our team of scientists, however, has developed a geographic and statistical model to downscale national public opinion results to the state, congressional district, and county levels. We can now estimate public opinion across the country and a rich picture of the diversity of Americans’ beliefs, attitudes, and policy support is revealed. For instance, nationally, 70% of Americans think global warming is happening. But the model shows that only 49% of people in Emery County, Utah agree. Meanwhile 72% in neighboring Grand County, Utah believe global warming is happening. Explore the maps by clicking on your state, congressional district, or county and compare the results across questions and with other geographic areas.
Beneath each map are bar charts displaying the results for every question at whichever geographic scale is currently selected. See the methods page for more information about error estimates.
