Methodology

Version 0.1 · 2026-09-02. This page is versioned; material changes are dated here and in the changelog.

Address resolution

Addresses are normalized (whitespace, state aliases) and geocoded with the U.S. Census Bureau Geocoder, which also returns the county and incorporated place. We do not invent or “correct” addresses; ambiguous input is returned to you for correction. Coordinates are stored in WGS84 and radius searches use true-distance (geography) calculations.

Reported crime activity

Registered-offender information

We link to the official NC State Bureau of Investigation registry search and notification tools. We do not cache, mirror, or republish registrant records, photographs, or profiles, and we do not create offender pages.

Coverage and freshness

Every source resolves to one of six states (current, delayed, stale, temporarily unavailable, coverage not available, integration pending). “No matching records were returned by this integrated source” is different from “coverage unavailable”, and we never present the latter as zero.

Consistency and fair housing

Everyone who checks the same address at the same time receives the same available results and methodology. We do not personalize or suppress safety results, do not describe the demographic character of an area, and do not recommend moving toward or away from any neighborhood.

Corrections

Use the contact form to request a correction. Administrators can mark an item disputed, suppress it from public view without deleting the source evidence, and link to corrected official information.
