Classed chloropleth maps represent values by variegated colors of shading in one color divided into several classes. The map above shows the population density of residents over the age of 65 in Philidelphia County. This map shows the darker areas as those which have higher percentage of residents over 65, and the lighter areas as having a smaller percentage and is divided into seven classes, each of which is assigned a color.
