Wetonka, South Dakota Demographics & Population 2026

A note before these figures: with a population of 7, Wetonka's ACS estimates come from a small number of survey responses and carry wide margins of error. Individual percentages below — particularly rates that round to 0% or 100% — are approximations, not precise measurements. See data.census.gov for the published margins of error.

Economy, Income & Housing

The ACS records no residents below the poverty line in Wetonka. In a community this small the estimate rests on very few survey responses, so it should be read as an absence of measurement rather than a measured absence of poverty. The survey records no unemployed residents in Wetonka, which reflects the size of the sample rather than a labor market without joblessness. Every occupied housing unit the survey reached in Wetonka was renter-occupied. At this sample size that indicates no owner-occupied homes were captured rather than that none exist.

Race & Ethnicity

Every resident counted in Wetonka was recorded as White (non-Hispanic). A figure of exactly 100.0% reflects a survey sample too small to capture the community's full composition rather than a precise measurement.

Education

40.0% of residents aged 25 and older hold a bachelor's degree or higher. This is 25% higher than the state rate of 31.9%. Nationally, 35.7% of adults hold at least a bachelor's degree. No surveyed resident aged 25 or older reported leaving school before earning a high school diploma, though a rate of exactly 100% reflects the limits of a small sample.
