Seats to Votes Distortion

Seats-to-Votes Distortion: measures the extent to which one party wins a greater percentage of seats than votes and the other party wins a smaller percentage of seats than votes. You add the percentage distortion for each party and divide by two. For example, if Democrats won 10% more seats than votes and Republicans 6% fewer seats than votes, the distortion would be 8.0%.
