Despite the overall metro area concentration of computer and mathematical occupations, individuals working in these occupations do reside throughout the Madison Region. While census tracts with high shares of residents are largely located in and adjacent to Dane County, other areas with notable shares include Dodgeville, Monroe and Lake Mills. These areas should not be surprising given the presence of several ecommerce related employers in these communities. In terms of the total number of computer and mathematical occupations by census tract, a large number of workers are concentrated in Verona, Middleton, Sun Prairie and Fitchburg. Madison’s west side and the areas near downtown and the isthmus also have a large intensity of workers residing in small geographic areas.
