Bivariate Choropleth Map



Original Location: http://www.personal.psu.edu/acr181/election.html


This bivariate choropleth map analyzes John Kerry's vote share and the population of an area in the 2000 election. As the cartographer says "Places that are green are high in Kerry votes but low in population, and places that are purple are simply high in population." A combination of the two colors represents areas high in both population and Kerry votes.
