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.

Every occupied housing unit the survey reached in Stephan was renter-occupied. At this sample size that indicates no owner-occupied homes were captured rather than that none exist.
