There are approximately 50,000 personal injury law firm businesses in the United States. The latest widely cited estimate counts 50,435 personal injury lawyer and attorney businesses in 2025.
The exact total depends on how "personal injury law firm" is defined. Public estimates place the number between about 50,000 and 64,000 firms or businesses.
U.S. Personal Injury Law Firm Count
| Measure | Estimated number | What it means |
|---|---|---|
| Personal injury lawyer and attorney businesses | 50,435 | 2025 industry estimate based on the IBISWorld personal injury lawyers and attorneys category |
| Alternative 2023 estimate | 64,331 | Older figure cited in a 2024 professional insurance presentation using IBISWorld data |
| All offices of lawyers | 165,491 | 2023 Census count covering every legal specialty, not only personal injury law |
| Active U.S. lawyers | Approximately 1.37 million | ABA's 2025 count of active lawyers across all practice areas |
Why Is There No Single Official Number?
There is no single official national count because the U.S. Census Bureau does not maintain an industry category exclusively for personal injury law firms. Its primary classification, NAICS 54111: Offices of Lawyers, includes personal injury, criminal, corporate, family, estate, real estate and other legal practices.
Industry research companies estimate the personal injury segment using business databases, Census data, revenue estimates and industry classifications. Those methods can produce different totals because:
- Some firms handle personal injury along with workers' compensation, medical malpractice or general litigation.
- A law firm may operate multiple offices.
- Business databases may count offices, listings or legal entities differently.
- Some estimates include defense-side tort practices and structured-settlement specialists.
- Firms open, close, merge and rebrand over time.
What Number Should Businesses Use for Market Sizing?
Businesses should use 50,435 personal injury law firm businesses as the current national estimate. The figure is recent, specific and tied to the personal injury lawyers and attorneys industry category.
For broader competitive analysis, use a range of 50,000 to 64,000 firms and identify the source and year. The Census figure of 165,491 offices of lawyers should not be used as the personal injury firm count because it covers every type of legal practice.
What Does the Estimate Include?
The estimate includes businesses connected with personal injury legal services, such as:
- Automobile and truck accident claims
- Premises liability
- Medical malpractice
- Product liability
- Wrongful death
- Workers' compensation-related injury work
- Tort litigation
- Structured settlements
Not every business in the category focuses exclusively on plaintiff-side personal injury cases. The figure is best described as an industry estimate of personal injury law businesses, rather than an audited count of dedicated plaintiff personal injury firms.
Bottom Line
Use 50,435 businesses as the best current national estimate. When the source or definition covers a broader group of firms, report the range as about 50,000 to 64,000.
