Dot density maps are a type of point pattern map that use dots to represent a certain numerical value. Unlike, continuously graded and range-graded proportional maps, in dot density maps the dots do not vary in size. In this specific dot density map, the hispanic population is represented in the United States. One dot represents 100,000 people of the Hispanic race. It looks as if California, Texas, and Florida have the largest Hispanic population.
