Each dot on a dot-density map represents some amount of data. In a dot-density map, areas with many dots indicate high concentrations of values for the chosen field and fewer dots indicate lower concentrations. This Maptitude dot-density map shows the distribution of the Hispanic and Non-Hispanic population.

How does a dot distribution map work?

Dot maps rely on a visual scatter to show spatial patterns. in other words, A dot map is a statistical map that uses dots of fixed size to represent a fixed number of units in a particular area. They employ a base map of a concerned area and a dot is drawn exactly on the appropriate location on the map.
