This Map Displays the Partisan Voting Index Value for each county in New Jersey. The Partisan Voting Index (PVI) is a measurement of how strongly a county leans toward the Democratic or Republican Party. The PVI is calculated by taking the average percentage for the winning party in a county for the last two elections and subtracting that value from the national average for that party in the same two elections. The data is based on results from the 2020 and 2016 presidential election.
