Ziebach County, part of the Cheyenne River Reservation, is still the most impoverished county in the entire country with a rate of 54.4 percent. South Dakota has three counties among the top 10, with an additional four in the top 50:
- Ziebach County, 54.4 percent, #1
- Shannon County, 46.0 percent, #4
- Todd County, 40.1 percent, #7
- Buffalo County, 37.7 percent, #14
- Corson County, 34.9 percent, #27
- Mellette County, 34.3 percent, #35
- Bennett County, 33.8 percent, #38
The Census Bureau published a thematic map displaying rates of poverty by county. It's interesting to not only look at the distribution of poverty throughout South Dakota, but also its concentration (or lack thereof) in particular areas of the nation.
