New York workers' compensation claims, county by county

How many workers' compensation claims the New York State Workers' Compensation Board assembles in each county every year, how often the injured worker has an attorney or representative, and how many claims are fought, reach hearings or end in permanent disability. We aggregate the Board's own claim file on the server, read no individual claim, suppress every count of 1 to 10 claims and check the totals against the Board's other published views of the same table.

What is in this dataset?

Workers' compensation claims assembled by the New York State Workers' Compensation Board in every New York county, for each accident year from 2000: the number of claims, how many have an attorney or representative (count and share), how many are controverted, how many have had a hearing and how many hearings were held, and how many are classified permanent partial or permanent total disability or occupational disease. Built only from SoQL aggregates of the Board's 5.7-million-claim file on NY Open Data (no claim-level row is read), with every count of 1 to 10 claims suppressed.

Use it to size the workers' compensation market in New York county by county: how many claims are assembled each year, how often injured workers are represented (a measure of how much of the market lawyers already serve), how many claims are fought, and how many reach hearings and permanent disability. Pair it with the work-injuries and law-offices datasets by county FIPS code. Agents can look up New York, compare years, or search a county by name.

Where does the data come from?

Aggregated on the server with SoQL from the Board's 'Assembled Workers' Compensation Claims: Beginning 2000' view on NY Open Data, grouped by county of injury and accident year; no claim, claimant, employer or narrative field is read. A count of 1 to 10 claims is suppressed, and a hidden cell is never derivable from its row. A gate re-queries 50 county-years live, ties the county sums to the view's total and to an independent GROUP BY year, and checks them against the Board's own filtered views of the same table.

Not legal advice. These are counts of claims the Board assembled, not claims accepted or paid, and a share with an attorney says how often workers were represented, not whether they needed to be. Questions about a workers' compensation claim are for a licensed New York attorney or the Board.

What changed recently?

  • 2026-10-29 · Assembled workers' compensation claims in every New York county for accident years 2000 to 2026, with the share represented by an attorney, controverted claims, hearings and permanent disability classifications: 5,655,563 claims in the Board's file. (source)

The full log is in changes.json.

What are the limits?

  • New York only. Other states publish claim data differently or not at all, so these figures do not compare with another state's.
  • A claim is assembled when the Board learns of an injury that cost more than a week of work, is serious, is disputed or is claimed on Form C-3. Assembled is not accepted or paid, and minor first-aid injuries never appear.
  • The share with an attorney or representative is the Board's flag on the claim today. It says how much of the market lawyers already serve, not how much they should.
  • The county is where the injury happened (injured_in_county_name), not where the worker lives or the employer is based. A small number of claims have no county; they have their own Unknown record.
  • Counts of 1 to 10 claims are suppressed, and a county-year with fewer than 11 claims has every count suppressed. Recent accident years are flagged preliminary because hearings and permanent disability awards are still being added; they will rise.
  • The Board refreshes the file quarterly and can revise past values; a changed published value is logged on the corrections page.
  • Records older than 130 days since their last check are marked stale in the files until we re-check them. Every confirmed error we fix is listed in the data corrections log.
