35 registrants are listed for ZIP 78121 — a ratio of 1 per 356 residents.
County baseline — Wilson County overall: 1 per 361 residents.
Counts describe density, not danger by themselves; proximity to a specific address is what matters. This page publishes the count only — never names, photos, or registrant addresses. For the address-level check, search the official registry: the Texas Public Sex Offender Website / Sex Offender Registry (Texas Department of Public Safety), or every state at once through the federal NSOPW site.
One honest caveat: this count comes from a compilation of the state registry’s published data. Where a registry also lists work or school locations, a compilation count can read higher than a residence-only official count — the official search above is the deciding check for a specific address.
