Where construction work is most dangerous, by the numbers

Real OSHA severe-injury reports for construction trades, normalized by the federal count of construction businesses in each state. Aggregate only — a state and trade-sector view, never a ranking of any individual contractor.

Read this before the ranking: two honesty rules

  • This is aggregate only — never a contractor scorecard. Every figure is a state total or a trade-sector total. OSHA reports injuries at the establishment level, but attaching a severe-injury event to a named business in a public directory is a defamation class we refuse to touch. There are no business names, no EINs, and no per-contractor rows anywhere in this study or its open data.
  • Only federal-OSHA states are ranked. Federal OSHA is the system of record for private-sector construction injuries in 30 states. The other 21 are OSHA State-Plan states that run their own private-sector reporting — so their severe injuries are largely absent from this federal dataset. Ranking them here would publish a near-zero rate that reflects reporting jurisdiction, not safety. We name them below and withhold a rate.

Federal-OSHA states, ranked by severe-injury rate

OSHA Severe Injury Report events in construction (NAICS 236/237/238) per 1,000 BLS QCEW construction establishments, 2015–2025. The median is 32 per 1,000 — read the rate as an incidence signal across each state's establishment base, not a verdict on any one contractor.

OSHA State-Plan states — named, not ranked

These 21states run their own private-sector severe-injury reporting, so the federal dataset undercounts them. We list the federal-only count for transparency, but we do not compute a per-1,000 rate from it, because that number would measure reporting jurisdiction rather than safety. For these states, consult the state plan's own published data.

By construction sector

The aggregate severe-injury and fatality counts across the three construction NAICS sectors (all states, all years in the pull). Specialty trade contractors (NAICS 238) — the plumbers, electricians, roofers, and concrete crews most homeowners hire — carry the largest share.

How construction workers get hurt

The most common event mechanisms behind the severe-injury reports, largest first. Falls to a lower level dominate construction severe injuries — which is why fall protection is OSHA's most-cited construction standard year after year.

Methodology and honesty notes

  • Aggregate only — no per-contractor attribution. The committed seed holds state and NAICS-sector rollups plus a national injury-type mix. No establishment name, EIN, or per-contractor row is included or reconstructable. Per-pro OSHA attribution is a defamation class; we publish the rollups and nothing finer.
  • Numerator. OSHA Severe Injury Reports (mandated reports of work-related hospitalizations, amputations, and eye losses, 29 CFR 1904.39) plus Injury Tracking Application summaries, filtered to construction NAICS 236/237/238, summed by state.
  • Denominator. 2024 BLS QCEW construction establishment counts, summed over the same NAICS scope (236+237+238) for the same state — so the rate is numerator and denominator from a consistent construction definition.
  • Federal vs. State-Plan (the load-bearing caveat). Only the 30 federal-OSHA states are ranked. The 21 OSHA State-Plan private-sector states run their own reporting, so their federal counts are an undercount; we name them and withhold a rate rather than publish a misleading one.
  • What the rate is not.A severe-injury report is a serious outcome, not a citation or a penalty (OSHA's inspection/violation tables require a separate API key we do not key here, so this study makes no citation or fine claims). The rate is an incidence signal across an establishment base, not a measure of any single business's safety.
  • Establishment-name non-uniqueness + report lag. OSHA establishment names are not unique and reports can be revised or contested after filing, so even the aggregate totals carry the normal public-records lag. We aggregate to defuse both — small per-record noise washes out in a state or sector sum.
  • Source + license. AGGREGATE ONLY — state and NAICS-sector rollups plus a national injury-type mix. No per-contractor row, name, or EIN is included or reconstructable. A 'severe injury report' is an employer's federally-mandated report of a work-related hospitalization, amputation, or loss of an eye (29 CFR 1904.39). The federal SIR program is the system of record for private-sector construction only in federal-OSHA states; the 21 listed OSHA State-Plan states run their own private-sector reporting, so their federal counts are an undercount and no per-1,000 rate is published for them. Public domain (17 U.S.C. 105). OSHA / U.S. Department of Labor + U.S. BLS.
  • Computed live. Every number is read from the committed aggregate seed at render time. Rebuild the seed from a fresher OSHA pull and this page updates automatically — nothing here is hardcoded.

Why a contractor directory publishes this

Safety record is a real trust signal, but it is one that's easy to weaponize dishonestly. Plenty of sites would happily slap a red flag on a named contractor from an OSHA hit. We do the honest inverse: we publish the verifiable aggregate — which states and trades carry the most severe-injury risk — and we refuse to attribute a single event to a single business. Pair this with our license-lapse study and the establishment-density study for the full picture of any state's contractor landscape.

Frequently asked questions

Which state has the highest construction severe-injury rate?

Among the 30 federal-OSHA states, District of Columbia reports the highest rate — 107.6 OSHA-reported severe injuries per 1,000 construction establishments over 2015–2025 (146 severe-injury reports against 1,357 establishments). The median federal-state rate is 32 per 1,000. This is an incidence signal across each state's establishment base — not a per-contractor figure and not a ranking of any individual business.

Why are California, Michigan, and other big states missing from the ranking?

Because they are OSHA State-Plan states that run their OWN private-sector severe-injury reporting. Federal OSHA is not the system of record for private construction there, so their severe injuries are largely absent from this federal dataset — a near-zero federal count would be a reporting-jurisdiction artifact, not a safety record. We name all 21 of them and deliberately withhold a rate rather than publish a misleading one.

Is this a list of dangerous contractors?

No, and it deliberately cannot be. Every number on this page is an AGGREGATE — a state total or a trade-sector total. There is no per-contractor attribution anywhere, no business names, no license numbers. OSHA enforcement data is reported at the establishment level, but attributing safety events to a named contractor in a public directory is a defamation class we will not touch. We publish only the state and sector rollups.

What exactly is a 'severe injury report'?

Under 29 CFR 1904.39, employers must report every work-related in-patient hospitalization, amputation, or loss of an eye to OSHA within 24 hours (fatalities within 8 hours). Those reports are the numerator here, summed for construction NAICS 236/237/238 by state over 2015–2025. It is a count of severe outcomes, not minor injuries and not citations or penalties.

Where does the data come from, and can I reuse it?

OSHA Severe Injury Report events in construction per 1,000 BLS QCEW construction establishments. The numerator is OSHA's Severe Injury Reports + Injury Tracking Application (public records, public domain under 17 U.S.C. 105); the establishment denominator is 2024 BLS QCEW. We read both through ProFix's committed aggregate seed and recompute every figure live. The machine-readable data is at /api/construction-safety-by-state-2026.json, free to reuse with attribution.
