NHTSA Vehicle Safety API (Recalls, Complaints, Ratings)
U.S. Census Bureau Available APIs — Economic Census, Annual Survey of Manufactures, VIUS
Coverage, side by side
| NHTSA Vehicle Safety API | U.S. Census Bureau Available APIs — Economic Census, Annual Survey of Manufactures, VIUS | |
|---|---|---|
| Geographic | United States (vehicles and motor-vehicle equipment, tires included) | United States; Economic Census to county level, ASM national, VIUS national and state |
| Temporal | Model years 1949–2027 plus an equipment pseudo-year; complaint filings observed into August 2026 | Economic Census 2002–2022 in five waves; ASM 2018–2021; VIUS 2021 only |
| Granularity | One row per recall campaign, per ODI complaint, or per make-model-year combination | Industry-by-geography aggregate cells; VIUS rows are characteristic-by-state tabulations |
What each contains
They tie on 1 attribute. Pick by fit, not by loyalty.

Where they're equivalent
Four ways, exactly. Both are confined to the United States — NHTSA covers vehicles and motor-vehicle equipment sold or operated here, Census covers US establishments and the US truck population. Both score 9 out of 10 on Datadory's rubric, against that 7.81 catalog-wide average. Both ship fully verified field dictionaries, checked against live records rather than inferred. And both honor the same entity-plus-timestamp-plus-classification-plus-measure skeleton described above, so a normalized feed can carry them side by side even though nothing else about them matches.
Fair questions
Do the two field dictionaries overlap?
Only in skeleton. Both reduce a record to an entity, a time stamp, a classification and a count. Beyond that they diverge completely: NHTSA adds narratives, severity flags and named products; Census adds dollar measures, firm counts and NAICS classifications. No field transfers directly between them.
Which archive reaches further back?
Depends on the axis. NHTSA stretches furthest on vehicle age — model years 1949 through 2027, with complaint filings observed into August 2026. Census stretches furthest on measured structure — Economic Census waves back to 2002, Annual Survey of Manufactures 2018–2021, and a single VIUS snapshot of the 2021 truck population.
Can either record identify individual companies?
NHTSA can, Census cannot. NHTSA names the manufacturer of record on every campaign, resolves tire brands and product lines inside complaint product arrays, and carries a truncated VIN per complainant vehicle. Census publishes counts and dollar totals constructed so no single business can be isolated — ideal for sizing, silent on identity.
Which one fits an automotive parts-market analysis?
Usually both, because the strongest metric joins them: NHTSA defect events over Census denominators, such as complaints per thousand parts-retail establishments in a county, or recall severity weighted by the VIUS heavy-truck fleet. Start with whichever matches your question's first verb — *what broke* points at NHTSA, *how big* points at Census.
Can I get both records from Datadory?
Yes — sample both, pick by fit, or take both in one feed. Each arrives normalized to its documented field dictionary with sample rows attached for validation, delivered daily, weekly, or hourly, your call, so a defect stream and a county market structure can land in the same pipeline.
