KCIC's 2024 Report: 3,931 US Asbestos Filings. 85% in 15 Jurisdictions. One Firm Filed 1 in 5.

KCIC's 2024 Asbestos Litigation Year in Review: 3,931 filings, 85% in 15 jurisdictions, more than half from 5 plaintiff firms. The Gori Law Firm filed 788.

Asbestos Litigation Isn't Migrating. It's Concentrating: 5 Firms File Half of America's Asbestos Suits
Key Facts
KCIC’s 2024 Asbestos Litigation Year in Review recorded 3,931 US asbestos filings, essentially flat against 3,929 in 2023. A prior version of this report said 4,012, a figure the cited source does not contain.
85% of 2024 filings landed in just 15 jurisdictions. Madison County (882) and St. Clair County (820), Illinois, alone accounted for 43% of the entire national docket.
More than half of all US asbestos filings came from 5 plaintiff firms. The Gori Law Firm filed 788, about 20% of the national docket and roughly twice the next firm.
Talc allegations appeared in 19.1% of 2024 filings (751 of 3,931). The 22% figure in the prior version was a later 2025 mid-year number conflated with 2024.

The headline of the previous version of this report was a number the source it cited does not contain. KCIC did not record 4,012 US asbestos filings in 2024. It recorded 3,931, and that flat total is the first clue that the real story is not movement at all.

The asbestos docket is not migrating to new venues. It is concentrating, into a handful of courts and a handful of firms, and KCIC’s own 2024 Asbestos Litigation Year in Review documents exactly how tightly.

Total US filings were 3,931 in 2024, against 3,929 in 2023: essentially unchanged. Underneath that flat line, 85% of all filings landed in just 15 jurisdictions. Two Illinois counties, Madison and St. Clair, took 43% of the entire national docket between them. And on the plaintiff side, five firms filed more than half of every asbestos case in the country.

The Jurisdiction Concentration

Per the KCIC 2024 report, the asbestos map is two Illinois counties and a long tail. Madison County recorded 882 filings (22% of the national total, rank 1). St. Clair County recorded 820 (21%, rank 2, up 22% year over year). New York, New York followed at 317 and Philadelphia at 267.

Madison alone accounted for 809 mesothelioma filings, about 42% of all US mesothelioma filings in the data. The top 15 jurisdictions together held 85% of the docket. This is not a story of cases dispersing to new courts. It is the opposite: the same two venues continuing to anchor the national docket, with Illinois venue law (735 ILCS 5/2-101) the structural reason an out-of-state plaintiff can file in Madison when a named defendant sold products into Illinois.

The Firm Concentration

The sharper concentration is not the courts. It is who files in them. Per the KCIC 2024 firm table, The Gori Law Firm filed 788 asbestos cases in 2024, about 20% of the entire US asbestos docket and roughly twice the volume of the next firm.

Simmons Hanly Conroy filed 393. Weitz and Luxenberg filed 327. Maune Raichle Hartley French and Mudd filed 303. Those firms and the fifth-ranked firm together filed 51% of all US asbestos cases; the top 15 firms filed 74%.

One in five asbestos lawsuits in the United States in 2024 was filed by a single firm. That is the named, primary-sourced concentration finding the earlier version of this report gestured at but never delivered, because it was waiting for a future KCIC report instead of reading the firm table in the one it already cited.

The Disease and Talc Picture, Corrected

The 2024 docket was 1,907 mesothelioma filings and 1,644 lung-cancer filings. Mesothelioma fell 1.7% from 1,940; lung cancer rose 4.2% from 1,577. Mesothelioma is still the largest single disease category, but the growth was on the lung-cancer side.

Talc allegations appeared in 19.1% of 2024 asbestos filings, 751 of 3,931, up 17.9% year over year. The prior version stated 22%. That number is real but it is a KCIC 2025 mid-year figure, sold in the old draft as the 2024 story. Conflating two reporting periods to make a number look bigger is exactly the discipline failure this rewrite corrects: the verified 2024 figure is 19.1%, and that is what this report states. For how that share concentrates in mesothelioma specifically, see talc’s share of mesothelioma lawsuits.

The Source, Stated Honestly

There is no government count of national asbestos filings. KCIC’s annual report is the benchmark by default, not by audit. KCIC is a consulting firm that processes claims for many of the largest defendant companies, and its completeness figure is its own self-estimate.

Through that work, KCIC estimates that it receives and processes at least 90% of all complaints alleging personal injuries due to asbestos exposure.

KCIC 2023 Asbestos Litigation Year in Review, p.2

That single proprietary source is the inherent limitation of every national asbestos-filing story, including this one. The honest move is to state it plainly and to report only what the KCIC report itself prints, which is what this version does, rather than attaching the report’s name to a headline number it never published.

A Closing Thesis

The asbestos litigation map of 2024 is not being redrawn. It is being compressed. A flat national total, 3,931 filings, hides a docket where 85% of cases run through 15 courts, two Illinois counties hold 43% of everything, and five plaintiff firms file more than half of all asbestos suits in the country, with one firm alone filing one in five.

The prior version of this report missed that because it led with a fabricated total and then deferred its own conclusion to a KCIC report it was still waiting for, when the firm table that answers the question was on page 8 of the report it had already cited. The complementary Madison County filings investigation carries the single-venue history; this one carries the national concentration. Neither needs the other to be padded, and neither needs a number that the source does not contain.

Reader Q&A

Frequently Asked Questions

How many US asbestos lawsuits were filed in 2024?

Per KCIC's 2024 Asbestos Litigation Year in Review, 3,931 US asbestos personal-injury lawsuits were filed in 2024 (processed as of January 31, 2025), essentially flat against 3,929 in 2023. A prior version of this report stated 4,012 and attributed it to a KCIC press release that contains no such figure; the correct primary number is 3,931, from the report PDF itself.

What does 'concentration, not migration' mean here?

The asbestos docket is not spreading out to new venues. It is consolidating in a small number of courts and a small number of firms. Per the KCIC 2024 report, the top 15 jurisdictions accounted for 85% of all filings, and Madison County (882, 22%) and St. Clair County (820, 21%) in Illinois together took 43% of the entire national docket. On the plaintiff side, the top 5 firms filed 51% of all US asbestos cases and the top 15 firms filed 74%. That is concentration, and it is the finding.

Which plaintiff firms file the most asbestos cases?

Per the KCIC 2024 Year in Review firm table, The Gori Law Firm filed 788 cases, about 20% of the entire US asbestos docket and roughly twice the next firm. Simmons Hanly Conroy filed 393, Weitz and Luxenberg 327, and Maune Raichle Hartley French and Mudd 303. Those four plus the fifth-ranked firm account for 51% of all national filings. No other public source consolidates the national plaintiff-firm distribution; this comes directly from the KCIC report.

Why is Madison County, Illinois the top US asbestos venue?

Illinois venue law under 735 ILCS 5/2-101 permits filing in any county where a defendant has its principal place of business or is alleged to have committed the tort. National asbestos defendants have Illinois business contacts, so an out-of-state plaintiff can often file in Madison County if a named defendant sold products into Illinois. Madison County runs a dedicated asbestos docket. Per the KCIC 2024 report, Madison recorded 882 asbestos filings (22% of the national total) and 809 mesothelioma filings, about 42% of all US mesothelioma filings. The U.S. Supreme Court's 2017 Bristol-Myers Squibb decision limited specific personal jurisdiction over out-of-state claims but did not displace Madison's position in this data.

What is the mesothelioma versus lung-cancer split?

Per the KCIC 2024 Year in Review, 2024 saw 1,907 mesothelioma filings (down 1.7% from 1,940) and 1,644 lung-cancer filings (up 4.2% from 1,577). Mesothelioma remains the largest single disease category in the asbestos docket, but lung-cancer filings grew while mesothelioma filings slightly declined.

What share of asbestos filings involve talc?

Per the KCIC 2024 Year in Review, talc allegations appeared in 19.1% of asbestos filings in 2024 (751 of 3,931), up 17.9% year over year. A prior version of this report stated 22%; that figure is from a later KCIC 2025 mid-year update, not the 2024 report, and conflating the two periods was an error. This report states only the primary-verified 2024 figure. KCIC's talc series covers mesothelioma and lung cancer and excludes talc-ovarian claims.

How does KCIC count US asbestos filings, and how complete is it?

KCIC is a consulting firm that processes asbestos and toxic-tort claims for many of the largest US defendant companies. Its 2023 Year in Review states that KCIC 'receives and processes at least 90% of all complaints alleging personal injuries due to asbestos exposure.' That is KCIC's own self-estimate, and KCIC is a single proprietary defense-side source, which is the inherent limitation of all national asbestos filing data: there is no government national docket count, so KCIC's annual PDF is the benchmark by default, not by independent audit.

Where can someone with mesothelioma file a case?

Venue depends on the specific facts: where exposure occurred, which defendants are named, where those defendants have business activity, and where the person lived or worked. An attorney who handles mesothelioma cases can assess which venues are available for a given exposure history. Filing in a high-volume venue is one factor among several; strength of evidence, defendant solvency, and trust-fund eligibility affect case value more than venue alone. The complementary Madison County asbestos filings investigation covers the single-venue history in depth.
