## The dataset, reconciled

The yearly files are free at OSHA. What is sold is the work of joining them.

### What is added to OSHA's files

- **Ten years joined per establishment.** OSHA's own identifier changes between eras of the
collection; 1,067,782 establishments are reconciled from 3,184,341 kept annual summaries.
- **Amended filings resolved** — one summary per establishment and year, the latest.
- **Rates computed and checked** — TRIR and DART, blank when hours are inconsistent.
- **Industry medians** — by 4-digit NAICS and year, from the filers themselves.
- **EIN as the join key** — present for 2019 onwards on 82–89 % of filings.
