Understanding the Map

EveryDistrict’s Legislative District Index (LDI) is the gold standard of state legislative competitiveness. Our LDI ranks state legislative districts on a scale from 100 to -100, using statewide elections data. Districts with a score of 100 would vote for statewide Democratic candidates by an average of 100 points (with the Democratic candidate receiving 100% of the vote); districts with a score of -100 would vote for statewide Republican candidates by an average of 100 points (with the Republican candidate receiving 100% of the vote). For a more realistic example, a district with a score of 10 would vote for statewide Democratic candidates by an average of 10 points (meaning we would expect the Democratic state legislative candidate to win with 55% of the vote compared to the Republican winning 45% of the vote).

After the 2018 election, EveryDistrict reviewed and enhanced our LDI system, improving the accuracy of the metric with new methodologies and the most recent electoral data.
