Choropleth Maps


Choropleth maps are thematic maps based on predefined aerial units; areas are distinctly colored or shaded to represent classed values of a particular phenomenon or variable. Some examples of a variable include population density or political affiliation. It makes it easy to visualize how the measured variable changes across and area. The map above is considered a choropleth map. The group of data is organized as a ratio value; a graded color series is used to show least intensity to most intense. This map shows the percent of people who are Hispanic or Latino per county in Florida.
