FIGURE 1—Predicted values for Manhattan block distance (in miles) to the nearest supermarket, by tertiles of percentage African American and percentage poor.
Note. Because the spatial linear trend was removed from distance to the nearest supermarket, the absolute values of the predicted values along the y-axis are not meaningful. The relative differences among groups are meaningful.
