Thematic Map


A Thematic Map is a map that is designed to provide cartographical information thematically, as its name implies.  A Thematic Map can use a wide variety of data to focus its theme on--from public debt to tallest buildings to average temperatures in a given month to birth rate and death rate maps.  This particular map focuses on the number of New Businesses in the United States.  The data is plotted through the use of color with the lightest shades representing the lowest numbers and the darkest shades representing the highest numbers (from 0 to 7,000+).
