Which places in South Dakota have the highest income per person?
The survey publishes income per person without a top code, so it gives a figure even for the richest places: Dakota Dunes has the highest estimate, $79,557 per resident (±$17,350), but it is within the margin of error of Big Sioux Township ($76,736): the survey cannot say which is higher.

How is this ranking made?
Each place's median household income is read from the 2020-2024 American Community Survey. A place enters the ranking if it had 1,000 or more residents in the 2020 Census and its estimate has a coefficient of variation of 40% or less. Ties in the published figure share a rank. This is a measurement of one figure, not a judgment of a place.
Towns and townships are ranked beside cities, villages and census-designated places, and a census-designated place can lie inside a township, so one area can appear twice, once as each.
