Figure 1

Three maps of Lafayette and West Lafayette with simulated household locations. Left: 120 red points at exact locations, which could identify households. Middle: the same points aggregated to census tracts, shaded from light to dark red by count, so only totals per tract are shown. Right: donut geomasking, where every point has been moved a random distance between 250 and 750 meters; one point's true location is marked with an x inside an orange ring showing the area its masked point could fall in.
Two ways of protecting individual locations.
