Question

What is the difference between a dot-density map and a choropleth map?

Answer 1

Dot maps use dots to represent a stated amount of some phenomenon within a political unit. Using a scale equating one dot with 1,000 people, 12 dots in one area would represent 12,000 people living in that area. On a choropleth map each political unit is fulled in with a distinguishing color or pattern but nstead use lines to join points of equal value across the mapped area. So in short, one map uses dots, and the other uses lines. 

Answer 2

Dot Destiny maps show the geographic density distribution of a phenomenon by placing dots representing a certain quantity of the phenomenon where they are most likely to occur. 

And a Choropleth map show where areas are shaded according to a prearranged key, each shading or colour type representing a range of values. 


So Dot Destiny map uses dots, while chropleth uses Shades
