Sample Illustration: Wisconsin Lung Cancer Incidence, 2010-2015

Using data from the Wisconsin Cancer Reporting System, members of the GEOSR team discovered lung cancer incidence rate is indirectly age-sex standardized and smoothed using adaptive spatial filtering.

Red areas on the map indicate higher rates than expected and blue areas indicate lower rates than expected, given the regional rate. Areas without color exhibit rates close to the regional rate.

The “Percent Minority” layer displays the percent of people who identify as a minority in each Census Tract. This is layer is only visible at a higher Zoom level. Different layers can be selected and overlapped to observe patterns.

Data was obtained from the American Cancer Society (ACS) 2012-2016 estimates and EJScreen: Environmental Justice Screening and Mapping Tool maintained by the Environmental Protection Agency.
