A safer-street conversation should not depend on whether one model was typed three different ways.
Bad labels can move a problem down the list before it ever reaches a grant memo, council packet, or safety plan.
A ranking built from raw labels can turn a typo pattern into a headline. Cleaning is part of responsible reporting.
Fragmented records make it harder to see where training, forms, or review workflows are creating public confusion.
A real pattern can disappear into spelling noise.
Raw labels are not neutral. If a model is recorded several ways, a basic "top vehicles" chart undercounts it. The corrected view groups those labels into one analytical name, then keeps the raw variants visible.
Current example: Toyota CAMRY recovers 42,377 records that would otherwise sit under smaller aliases.
Honda ACCORD
Honda CIVIC
Toyota COROLLA
The leaderboard can move after labels are grouped.
This is where data quality becomes a decision risk. A raw-label chart can rank a vehicle lower simply because its records were scattered across aliases.

ZIPs most sensitive to raw labels.
These ZIP areas have the highest share of changed vehicle labels. They deserve extra caution before someone uses raw records to describe local crash patterns.
Current highest-impact ZIP: Unincorporated / 95387.
Messy labels become public blind spots.
This is not a blame scoreboard. It is an audit trail for the places where public crash records need the most translation before anyone should compare them.
A fragmented record can make a vehicle trend, crash cause, or neighborhood risk look smaller than it is. That affects public meetings, newsroom charts, enforcement reviews, grant narratives, and the everyday driver trying to understand local danger.
Jurisdiction currently uses the CCRS city label as a public reporting proxy until a dedicated police-department dimension is exposed.
Primary Collision Factor means the reported crash cause or violation. Those mappings are still being reconciled, so this page avoids showing a misleading 0.0% score.
The current rulebook.
These mappings are applied before the public pages calculate vehicle rankings. Raw source values are preserved, so every cleaned label can still be audited.
Raw values mapped into clean labels.
Summary totals include all vehicle labels. Example rankings filter out Unknown model labels so the public story focuses on resolved make-model cleanup.
The public report uses aggregate counts only and does not expose individual crash records.
Compares source vehicle labels to the current cleaned warehouse labels.
Reporting-jurisdiction examples use CCRS city labels as the public agency proxy because no separate police-department dimension is currently exposed in the mart.
ZIP impact examples require at least 100 party vehicle records in the selected window.
