Classed choropleth maps
The above map depicts a classed choropleth map. A classed choropleth map is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income. The map above depicts the 2004 presidential election.
Unclassed choropleth maps
The above image on the right shows an unclassed choropleth map. An unclassed choropleth map is a cloropleth map that used shading and variation of colors rather than set colors with a legend or key, making it unclassed. The confusion and uncertainty of the different shades of color make this type of map widely unused. You can see the side by side comparison between an unclassed and a classed map. The unclassed map contain no legend or key and does not vary in color as much.
Bivariate choropleth maps
The picture above shows a bivariate choropleth map. A bivariate map used a single map to show two variables by combining two different sets of graphic symbols or colors. This particular map depicts olympic athletes.
Univariate choropleth maps
Above is a univariate choropleth map. This type of map shows one variable being analyzed using standard classification methods of cholopleth maps. In this case we are shown the percentage of individuals living in poverty.
Standardized choropleth maps
This image shows a standardized choropleth map. Standardized choropleth maps contain data that are standardized or averaged, allowing for an accurate comparison of distribution amongst particular areas. The above map depicts a census taken for people 14 and under in Canada.
Unstandardized choropleth maps
This is a image of an unstandardized choropleth map. This map depicts the election results for 2004. Because the map uses raw data that isn't split into equal sections, it is considered unstandardized. The different shades of red versus the different shades of blue show the unequal points on the map.
