Run the tests
On this page, you can see the results of applying our tests to Congressional districts. We’ll show you the lopsidedness and asymmetry of the results, and estimate how the state would have looked without gerrymandering. If you’re new to gerrymandering and our site, pick a state and year on the “Basic” tab. If you have more experience (or you’re more daring), you may want to explore the tests in more detail using the settings found in the “Advanced” tab.
