PopCount City Coverage Map
PopCount uses the 2010 U.S. Census Database to determine the total
population within a contour, population within a city within a contour,
population within counties and population within minor civil divisions. Block
and group centroid retrieval is available along with several other options.
Contours are read from files generated from other ACSL programs and loaded into
PopCount. That contour is then used to determine which centroids are within and
which are without.
