These maps illustrate the total population per county by graduated symbol. Due to the categorical symbology, minimal changes in county population may not be expressible.

 

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.
