Dot distribution maps are maps that use dots in order to show the presence of a certain characteristic, phenomenon or geographical feature like population density of a certain region. This particular map was made using data from the Census 2000 Redistricting Data Summary File. The data shown on the map represents the population density by Census block in the TJPD (Thomas Jefferson Planning District) in 2000. The dots are randomly distributed within each Census Block. One dot represent two people.
