Context & methodology
ZIP Code Tabulation Area 46556 in Indiana is defined by the U.S. Census Bureau for statistical reporting. It closely matches USPS ZIP code 46556 but may differ slightly at edges — use these ACS figures as demographic benchmarks, not exact postal boundaries.
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.
