Although some internal variation will remain, it will be less than in a choroplethic map.
In particular, all census tracts in Douglas, Paulding, Forsyth, Rockdale, Coweta, Fayette, Henry, and (with one minor exception) Cherokee counties have the lowest class of population density in the choroplethic map, suggesting broad homogeneity of census tract population density throughout the outer suburban fringe.
This is easily accomplished in a GIS, which can also display the results in the form of choroplethic maps.
A second limitation of choroplethic maps is that they give the impression of abrupt changes at the boundaries of administrative areas (such as counties or census tracts), while representing population as a continuous variable across the entire land area.
However, with dasymetric mapping, these transitions are a better reflection of the true underlying geography of the area than the transitions in choroplethic maps, which are artifacts partially attributable to the arbitrary delineation of areal boundaries (Langford 2003).
