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 county, congressional district, and state levels.
We can now estimate and visualize differences in opinion across the county and a clearer picture of the diversity of Americans’ beliefs, attitudes, and support for policy comes into focus. For instance, nationally, 64% of Americans think global warming is happening. But the model shows that only 44% of people in Spencer county, Indiana agree. Meanwhile we estimate that 60% in the nearby Vanderburgh county, Indiana believe global warming is happening.

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.
