Context & methodology

About ZIP 57660 income statistics ($67,292 median)

ZIP Code Tabulation Area 57660 in South Dakota is defined by the U.S. Census Bureau for statistical reporting. It closely matches USPS ZIP code 57660 but may differ slightly at edges — use these ACS figures as demographic benchmarks, not exact postal boundaries.

An estimated 111 people live in this ZCTA. Median household income here ($67,292) is higher than Corson County County ($53,005). Operators sizing a local market often pair median income with mean income ($99,082) and the share of households earning $100k+ to gauge both typical and upscale demand.

The neighboring ZIP comparison table above lists adjacent ZCTAs with their own ACS estimates. Large gaps between adjacent ZIP codes are common — a few miles can separate very different income profiles, which matters for retail trade areas, service radius, and competitive positioning.

Small-area ACS estimates carry wider margins of error than state or county totals. The Census Bureau publishes guidance on interpreting confidence intervals (linked below). When a figure is critical to your analysis, download the underlying table from data.census.gov and review the margin of error column before citing it in a business plan or press release.

Data vintage: Census ACS 2024 5-year estimates (published 2026). Tables: B19013 (median HH income), B19001 (distribution), B19049 (income by age of householder).
