Map area data & how locations are grouped
Numbers on markers are crash counts. Areas use a 0.002° grid (roughly 180–220 metres across in Texas), not verified intersections. Names use the most common recorded street or intersection-pair label in each area across the loaded history; they are not verified neighborhood boundaries. Several areas may share a road name. Missing-coordinate records remain in the totals.

Methods, definitions and limitations
San Marcos city · Guadalupe County and Hays County. Reported city code 383; county codes 94, 105. Current Census place identifier 4865600 (2026 reference). These identifiers reconcile the reported source labels, not independently geocoded historical boundaries.
Source: public Texas Department of Transportation (TxDOT) crash records loaded for this publication. Guide focus: All reported crashes. All displayed totals, historical comparisons, maps, rankings and CSV rows use this cohort. Selected reporting period: exact recorded city label SAN MARCOS, Oct 1, 2025 to Sep 30, 2026. Each crash is counted once using its selected current record revision. This is not a metropolitan-area or police-agency-only filter.
Fatal crashes count events; deaths and serious injuries count people. Fatal and serious-injury crash groups use recorded severity codes 4 and 1. A crash can involve multiple vehicle or road-user types. Counts do not control for traffic or pedestrian activity, do not establish fault, and are not crash rates.
In the selected reporting period, 165 records lack usable Texas-range coordinates for Oct 1, 2025 to Sep 30, 2026 (the guide period, not the separate map year); 0 lack a usable hour; 17 lack a usable road label. 1,092 records are not assigned a usable intersection pair (including non-intersection crashes). Unknown categories remain in totals but not narrative rankings. Coordinates are not independently verified.
Latest 12 months means the latest available calendar month plus the preceding 11 months, clipped to loaded coverage; an unfinished final month is partial. Year to date means January 1 through the latest loaded date in that year, not through today. Historical charts and the map use the wider loaded history (Jan 1, 2022 to Sep 30, 2026); the monthly year-over-year chart shows up to five recent years. Map year, crash-type and outcome filters apply only to the map and its linked area table. Every matching record with coordinates contributes; there is no top-100 cap. Map locations are approximate grid centres, not exact crash sites. Area names use reported road labels, not verified neighborhoods. CSV contains aggregate tables, not individual crash records.
Loaded extraction intervals span the selected period. Source intervals do not guarantee complete reporting. New reports and amendments can change earlier months. Prepared 2026-10-17T22:31:03.099Z. Approved snapshots change only after an editor publishes an update.

- A table file you can open in a spreadsheet. Downloads contain grouped counts, not individual crash reports.
- Crash count versus risk
- A count tells you how many crashes were reported. Without knowing how much people drove, walked or cycled, it cannot tell you how likely a crash was on a trip.
- Location identifiers and severity codes
- These are source-system labels used to match places and classify recorded outcomes. They are not independent proof of a city boundary or the cause of a crash.
