Discrepancy-distance distributions by category of (a) density and (b) poverty: This figure shows a smoothed kernel density (similar to a histogram) for discrepancy-distances by category. Large discrepancy-distances indicate disagreement between the single-stage and multi-stage geocoding methods. Density is categorized using the number of residents per square kilometer in the census tract. Poverty is categorized using the percent of residents below the poverty line in the census tract.
