Exploring Housing Cost Data With Conditioned Choropleth Maps

Brent D. Mast
U.S. Department of Housing and Urban Development

Micromaps (for example, see Carr and Pickle, 2010) display multiple maps on the same exhibit, with different geographic units highlighted in each map. A conditioned choropleth map (CCM) is a type of micromap with multiple maps arranged in a panel layout conditional on one or two categorical variables, with highlighted regions shaded according to a main variable of interest. CCMs have been used in a wide variety of applications (for example, see Carr and Pickle, 2010; Carr, Wallin, and Carr, 2000; Carr, White, and MacEachren, 2005; Friendly, 2007).
