San Antonio’s 78248 ZIP code—associated with the Deerfield–Inwood area—recorded the city’s lowest measured enforcement response in 2025 among ZIP codes with substantial call and offense volume. The area produced 406 recorded offenses and 36 arrests—equal to 8.9 arrests for every 100 offenses.

ZIP code 78256 followed closely at 9.3 arrests per 100 offenses. Eight additional ZIP codes remained below 22 arrests per 100 offenses, placing all 10 far below the 2025 systemwide reference ratio of 43.7 arrests per 100 recorded offenses across ZIPs with at least one offense.

The 2025 ranking

The ranking includes San Antonio-area ZIP codes with at least 4,000 calls and 400 recorded offenses in 2025. Those minimums prevent very small ZIP-year records from dominating the results.

Rates are rounded. Arrest and offense totals are aligned by ZIP and year but are not necessarily one-to-one case matches.

The neighborhoods behind the ranking

The bottom 10 spans several very different parts of San Antonio—from established North Central communities and luxury-growth corridors to the Far West and Northeast sides. That geographic spread is important: the low arrest-to-offense ratios are not confined to one income level, one development pattern or one side of the city.

Where volume makes the finding harder to ignore

UTSA–Woods of Shavano ZIP 78249 carried the largest offense burden

The UTSA–Woods of Shavano area in ZIP code 78249 generated 43,447 calls and 4,021 recorded offenses—more offenses than any other ZIP in the bottom 10. Its 837 arrests produced a ratio of 20.8 arrests per 100 offenses. That placed it ninth in the ranking even though its workload was among the largest.

Hollywood Park–Thousand Oaks ZIP 78232 paired high volume with a low arrest ratio

The Hollywood Park–Thousand Oaks area in ZIP code 78232 recorded 24,746 calls, 2,806 offenses and 462 arrests. Its rate of 16.5 arrests per 100 offenses was the sixth-lowest in the qualifying group. The data classifies the ZIP as “high offense, low arrest,” reflecting the combination of meaningful offense volume and comparatively limited arrest activity.

Crownridge–La Cantera ZIP 78256 remained the most persistent low-ratio ZIP

The Crownridge–La Cantera area in ZIP code 78256 recorded arrest-to-offense ratios of 9.0 in 2023, 10.4 in 2024 and 9.3 in 2025. That three-year pattern is more important than a single-year fluctuation because it suggests the low ratio is persistent within the source data.

A three-year pattern

Every ZIP in the 2025 bottom 10 also posted a relatively low arrest-to-offense ratio during earlier years. Some improved in 2025, but the broader pattern did not disappear.

What residents and policymakers should ask next

A low arrest-to-offense ratio can have many causes. Some offenses may not have an identifiable suspect. Some investigations may extend beyond the calendar year. Arrests may occur outside the ZIP where an offense was recorded. Certain offenses may be reported after the fact, while other calls may not require an arrest at all.

That is why this ranking should become the beginning of a public-accountability conversation rather than the end of one. San Antonio should be able to explain:

• whether low-ratio ZIP codes also have longer call-handling or arrival times;
• how offense severity and call priority differ across neighborhoods;
• what share of offenses are cleared without an arrest;
• whether staffing, patrol coverage and investigative resources match workload;
• and whether the same ZIP codes remain low after controlling for offense type.

The public should not have to choose between raw call counts and broad citywide crime claims. ZIP-level data can show where demand, offenses and enforcement outcomes diverge—and where deeper explanation is warranted.
