These Dot Density maps visualize total population per county. Each dot represents up to 5,000 people. Note that the positioning of the dots is random and is not intentionally associated with the specific locations of population within a county.

 

The following maps all express population change by county in New York State from 1900 to 2010. The source data and cartographic boundary files were downloaded from the US Census Bureau. Note that the modern county boundaries are used to illustrate historical population data for each of these maps.
