| Spearfish | 12,551 | $59,731 | 89.5 | 102.9 | $950 | 399.7 | 82.4 |
The data reveals an interesting parity: both Sioux Falls and Rapid City share an identical COL Index of 88.1. This suggests that despite a population difference of over 127,000 people, the general cost of goods and services is uniform. Sioux Falls holds a slight edge in median income at $70,925, which is $831 higher than Rapid City's $70,094. The "value play" here is nuanced. If you prioritize career density and a wider range of corporate jobs, Sioux Falls is the logical choice. However, if you prefer a slightly smaller city with immediate access to world-class outdoor recreation (the Black Hills), Rapid City offers an equivalent cost of living with a different lifestyle trade-off. The lack of housing data indicates a market where rental and home purchase prices are highly variable and dependent on specific neighborhoods, a common trait in growing states.
Cost of Living Rankings
While the overall COL index is identical, a deeper dive into specific spending categories can reveal subtle differences in your monthly budget. This ranking sorts cities from the most affordable overall lifestyle to the most premium, based on available data.

| 9 | Sioux Falls | 90.3 | 74.8 | 96.1 |
| 10 | Rapid City | 90.3 | 77.1 | 96.1 |
With an identical overall score of 88.1, both cities tie for the title of "Most Affordable" in this dataset. This means that for every $100 you would spend in an average US city, you can expect to spend roughly $88.10 in either Sioux Falls or Rapid City. This pricing power makes South Dakota a standout among states with major metropolitan areas. The tie underscores a key theme: you don't sacrifice cost-of-living affordability by choosing the state's largest city. The decision, therefore, should be based less on cost and more on the lifestyle and career profiles we explore next.
