Vocational Rehabilitation Services (U.S., NAICS 62431)

A rollup primer. NAICS 62431 is a single-child industry — it contains exactly one national industry, 624310, and is economically identical to it. This page gives the level's own ground-truth statistics and points you to the 624310 primer for the full detail.

1. Overview

Vocational rehabilitation ("VR") is the business of helping people who face barriers to work — most often a physical, intellectual, developmental, or psychiatric disability, but also injured workers, veterans, and the long-term unemployed — prepare for, find, and keep a job. The work is delivered through counseling, skills assessment, job training, job coaching, supported employment, and placement, and historically through "sheltered workshops" where workers with disabilities did paid production work in a segregated setting.[1]

The single most important fact about this level: it is not primarily a private, profit-seeking market. It is a government-funded social service delivered mostly by state agencies, nonprofits, and a minority of private contractors. The largest customer is government, the largest provider type is the local nonprofit, and the field's best-known names — Goodwill, Easterseals, and the affiliates of The Arc — are charities, not companies. That shapes who can invest and how money is made, and it is covered in full in the child primer.

2. What's inside — and why this level equals its one child

In the North American Industry Classification System ("NAICS"), a five-digit code is an "industry" that groups one or more six-digit "national industries." NAICS 62431 has only one such child:

Child code Name Share of the level
624310 Vocational Rehabilitation Services 100%

Because there is exactly one child, the five-digit industry (62431) and the six-digit national industry (624310) describe the same set of establishments and the same economic activity. Every figure, every provider, and every regulatory force at 62431 is simply the 624310 story at a different digit of the code. This page therefore stays short: read primer-624310 for structure, ownership mix, revenue channels, demand drivers, regulation, consolidation, and the full risk and how-to-invest discussion.

3. Size of this level

Our ground-truth U.S. federal statistics for NAICS 62431 (identical to 624310):

Metric Value Source (year)
Establishments 6,826 Census County Business Patterns (2023)[2]
Paid employment 223,984 Census CBP (2023)[2]
Annual payroll $7.05 billion Census CBP (2023)[2]
First-quarter payroll $1.69 billion Census CBP (2023)[2]
Firms 3,895 2022 Economic Census[3]
Receipts $14.35 billion 2022 Economic Census[3]
4-firm concentration (CR4) 8.0% 2022 Economic Census[3]
8-firm concentration (CR8) 13.5% 2022 Economic Census[3]
20-firm concentration (CR20) 23.3% 2022 Economic Census[3]
50-firm concentration (CR50) 32.7% 2022 Economic Census[3]
Herfindahl-Hirschman Index (HHI) 35.5 2022 Economic Census[3]

("CR4"/"CR8"/"CR20"/"CR50" are the combined revenue share of the largest 4/8/20/50 firms; "HHI," the Herfindahl-Hirschman Index, sums the squared market shares of all firms on a 0–10,000 scale, where higher means more concentrated.)

Two things to read from these numbers. First, the industry is extraordinarily fragmented: the four largest firms hold about 8% of receipts, the top 50 hold under a third, and an HHI of 35.5 is about as unconcentrated as U.S. industry statistics get — competition is local or state-specific, not national.[3] Second, average pay works out to roughly $31,500 per paid worker ($7.05 billion across 223,984 employees), very low because the head-count mixes program staff with the workers-with-disabilities doing paid production in workshops, many at subminimum wages.[2] (Note the payroll and establishment figures are 2023 while receipts and concentration are 2022, so they are not a single-year income statement.)

Undercount caveat — large, and in two directions. County Business Patterns ("CBP") counts only private and nonprofit employer establishments; it excludes the self-employed, firms without employees, and most government workers.[4] So it entirely misses the government backbone of this field — the federal State VR Services Program alone obligated roughly $3.96 billion in FY2024, and the state agency counselors it funds are not in these numbers at all.[6] At the same time, much of the real activity of "helping people with disabilities work" is booked in adjacent NAICS codes (Medicaid-funded services for people with intellectual and developmental disabilities, workers'-compensation return-to-work, youth-transition programs), so 624310/62431 also undercounts the true footprint of the field. The federal file provides no legal-form split, payer mix, growth rate, or margin for this level, so those are not stated here.

4. Investable universe — where value concentrates

Because the level equals its one child, value concentrates exactly where the 624310 primer describes: there is no listed pure-play, and the government-and-nonprofit core (state VR agencies, Goodwill, Easterseals, Arc chapters, and local Community Rehabilitation Programs) cannot be bought as a stock. Public markets offer only adjacent exposure — workers'-compensation return-to-work (e.g., CorVel, NASDAQ: CRVL), occupational health (Concentra, NYSE: CON), and broad government-workforce contracting (Maximus, NYSE: MMS; Serco, LSE: SRP). The more direct exposure is private: private equity has rolled up for-profit providers of Medicaid-funded disability supports and workforce services (the 2025–26 sale of ResCare Community Living to Sevita for $835 million is the clearest recent example).[15][14] The full company-by-company table, with scale and caveats, is in §4 of primer-624310.

5. How the money works

Government pays, so the economics look nothing like a normal service business. Providers blend several channels: state VR-agency fees under the Rehabilitation Act (as amended by the Workforce Innovation and Opportunity Act, "WIOA") — the dominant channel, ultimately ~79% federal money; milestone/outcome payments that pay for durable placements rather than hours; Social Security "Ticket to Work" and cost-reimbursement; Medicaid Home- and Community-Based Services ("HCBS") waivers for people with intellectual and developmental disabilities; workers'-compensation and disability-management fees from insurers and employers; and earned production revenue from workshops and the federal AbilityOne purchasing program.[6][10][11][12] The "product" is a lasting job placement; cost is overwhelmingly labor, so margins are thin, scale is hard, and there is little pricing power against a government payer. See §5 of primer-624310 for the unit economics and the metrics that matter.

6. Demand drivers

The structural driver is the disability employment gap: in 2024 the employment-to-population ratio for people with a disability hit a series high of 22.7% (22.8% in 2025), still far below the 65.5% ratio for people without a disability, against a population of 33.9 million people with a disability aged 16 and over.[7] Rising disability prevalence, tight labor markets, and policy mandates (WIOA reserves at least 15% of federal VR funds for student pre-employment transition services) all push demand up. But because the field is publicly funded, the real lever is government budgets — the federal VR grant, Medicaid HCBS budgets, and state matching capacity — not raw need.[6][13] Full detail in §6 of primer-624310.

7. Regulation

Regulation is not just a constraint here — it is the business model and its principal disruption risk. The Rehabilitation Act (via WIOA) funds the State VR Services Program and, through "Competitive Integrated Employment" policy, is steering the whole system toward real jobs at real wages and away from segregated workshops. The central transition is the phase-out of Section 14(c) of the Fair Labor Standards Act ("FLSA"), which since 1938 has let employers pay workers with disabilities below minimum wage: a December 2024 federal proposal to end it was withdrawn on July 7, 2025, leaving the certificate in place — but 18 states had already banned subminimum-wage work as of January 2025, so the legacy model is being dismantled state by state regardless.[8][9] The Americans with Disabilities Act, the Olmstead integration mandate, Section 504, and the AbilityOne program round out the framework. See §7 of primer-624310.

8. Consolidation

The core industry is about as fragmented as any in the U.S. economy (~3,895 firms, CR4 of 8%, HHI of 35.5), and the nonprofit/government side is unlikely to consolidate because the work is labor-intensive and locally delivered.[3] Where consolidation is happening is in the for-profit adjacencies — Medicaid-funded disability services (the Sevita–ResCare deal, cleared only after an FTC-mandated divestiture of 128 locations), government workforce services, and occupational health.[15][14] The likely path is a platform combining VR, HCBS, workers'-comp, and case-management technology, not a national roll-up of identical VR clinics. Full discussion in §8 of primer-624310.

9. Risks

The dominant risk is appropriations and reimbursement: revenue depends on federal VR grants, Medicaid budgets, and state matching capacity, and providers have almost no pricing power against a single-buyer (monopsony) government payer. Layered on top are business-model obsolescence (the 14(c)/workshop model being phased out), chronic labor scarcity and margin pressure, outcome-payment risk, regulatory and safeguarding exposure, and the analytical trap that diversified parents rarely disclose their VR revenue separately.[8][9] The listed adjacencies carry different, more cyclical risks (claims volumes, employment levels, government-contract cycles, healthcare reimbursement). Full list in §9 of primer-624310.

10. How to invest and the outlook

There is no ETF or listed company that gives clean exposure to NAICS 62431. Public-market routes are adjacent only — CorVel (CRVL), Concentra (CON), Maximus (MMS), and Serco (SRP) — and an investor buying them is buying insurance-services, clinic, and government-contracting businesses, not the social-service core. The more direct exposure is private equity in for-profit Medicaid-funded disability and workforce providers, where returns hinge on VR and Medicaid rates, caseload, and regulatory tolerance for consolidation.

The balanced judgment: the need this level serves is large, growing, and politically durable, and the long-run direction — more Americans with disabilities in real, integrated jobs — is clear. But it remains a government-funded, low-margin, deeply fragmented social-service field in the middle of a forced model change, with only thin and indirect ways for public-market capital to participate. For the full how-to-invest checklist, private-market diligence questions, and near-term signals to watch, see §10 of primer-624310.
