Slate Canvas Map-This map features the thematic data as the focal point. By using a receding neutral background with monochromatic colors, labels, and features, only key information is represented to provide geographic context. This map was developed by Esri using NAVTEQ data for North America, DeLorme basemap layers, and Esri basemap data. Worldwide coverage is provided from Level 0 (591M scale) through Level 8 (2M scale), and in North America from Level 9 (1M scale) through Level 16 (9k scale).
Layers
Population Change: The red and blue dots in this map represent small areas that declined or grew in population since 2000. Each dot represents a number of people in a census block, block group, or tract. Blue represents growth, red represents decline.
US Congressional Districts: Each 112th Congress boundary is colored according to whether it gained or lost population in total. By showing the Population Change dots within the district's boundary, interesting patterns sometimes emerge. A growing district may have pockets of decline, for example.
State House Districts Each state house boundary is colored according to whether it gained or lost population in total. By showing the Population Change dots within the district's boundary, interesting patterns sometimes emerge. A growing district may have pockets of decline, for example.
State Senate Districts: Each state senate boundary is colored according to whether it gained or lost population in total. By showing the Population Change dots within the district's boundary, interesting patterns sometimes emerge. A growing district may have pockets of decline, for example.
