clusters of poverty within the Navajo Nation—some single-chapter and geographically compact (e.g., the Alamo and Tóhajiilee chapters in New Mexico) and others more sprawling (e.g., a cluster of roughly 15 chapters centered around the Manuelito and Tsayatoh chapters and spreading across the Arizona–New Mexico border).

  • Percent of civilian labor force unemployed: Again, viewed as a whole, the Navajo Nation’s unemployment rate (estimated for the presentation at 15.6 percent) exceeds—and is nearly double—the national level. For this map, deriving the percent unemployed by chapter from the ACS data, the Division of Economic Development did not superimpose any graphic device to call attention to particular clusters because the areas with the highest unemployment rates (higher than 36 percent) stand out very prominently on the map: a north-south line of New Mexico chapters running from Whiterock to Smith Lake and four chapters in Arizona near the eastern border of the Hopi Indian Reservation, which is geographically an enclave in the main Navajo Nation landmass.
  • Median household income: Tsosie’s department’s calculations suggest that median household income in the Navajo Nation ($26,232 per year) is just under half of the median income for the United States as a whole. Mapped by chapter, the higher median-income chapters tend to be on the edges of the Navajo Nation’s land area—most strikingly, in a line along the western border of the nation from Lechee and Coppermine in the north to Leupp in the south (or, roughly, from Page, Arizona, to just east of Flagstaff, Arizona). In particular, Tsosie said that his division is using this map (in combination with the unemployment map) to reevaluate the division’s strategic development plans, seeing how the maps coincide (or not) with developing commerce centers within the Navajo Nation.
  • Percentage of people whose spoken language is something other than English: As a crude measure of speakers of the Navajo language, the Division of Economic Development calculated the percentage of each chapter’s population that reported speaking a language other than English; presumably, this mainly identifies speakers of the native Navajo language and its dialects. About 70.7 percent of the entire on-reservation Navajo Nation population speak a non-English language, per the presentation’s calculations. Though there are pockets of non-English concentrations on the northern and eastern edges of the Navajo Nation’s lands, the general impression from the map is a radial pattern—strongest concentration in the chapters in the northeast corner of Arizona and spreading (to lower concentrations) away from that center. This map, and the underlying data, are now being examined by education authorities within the Nation, because it does have implications for the service populations of educational institutions. As an aside, Tsosie also noted that this map also serves as a
