Legal Counsel and Prosecution (U.S.) — NAICS 922130

1. Overview

North American Industry Classification System (NAICS) 2022 code 922130 covers government offices that prosecute crimes and provide legal counsel on behalf of the public — district attorneys, state attorneys general, U.S. Attorneys, city and county counsel, and public defenders.[1] It sits inside the Public Administration sector, not the private economy. Put plainly: this is not an industry anyone owns. It is a taxpayer-funded government function, staffed by public employees and paid for out of federal, state, county, and city budgets.

Why should an investor care about a category with no companies in it? Two reasons. First, it is a large and durable pool of government spending — courts, prosecution, and public defense together run tens of billions of dollars a year — and that spending flows to a growing set of private vendors and service providers. Second, the case volume and workflows here drive demand for software, digital-evidence platforms, legal research, forensic tools, and outsourced legal services sold by public and private-equity-backed companies. You cannot invest in a prosecutor's office. You can invest in the businesses that equip and support one.

• Public-market way in: government-technology ("GovTech") and legal-information vendors — Tyler Technologies, Axon Enterprise, Thomson Reuters, RELX (LexisNexis), Motorola Solutions, Cellebrite, and consumer-legal platform LegalZoom. All touch this ecosystem, but none derives the majority of revenue from it.
• Private-market way in: specialist justice software (e.g., Karpel), electronic-discovery ("e-discovery") and legal-administration firms (Epiq, Consilio), alternative legal-services providers ("ALSPs") and on-demand legal talent (Axiom), plus — as the for-profit mirror of this government function — the private legal-services industry (NAICS 5411), a roughly $300-billion sector that is excluded from this code.[2]

Everything below distinguishes what is reported (federal statistics, company filings) from forward-looking judgment (clearly worded as such).

2. What it is and how it's structured

Scope. NAICS 922130 is "government establishments primarily engaged in providing legal counsel or prosecution." The Census Bureau's illustrative examples are attorneys general offices, district attorneys' offices, public defenders' offices, and public prosecutors' offices.[1] These offices do a few core jobs:

• Prosecution — charging and trying criminal cases (the "people" or "state" side). Federally, this is the 94 U.S. Attorney offices; at the state level, district attorneys and their equivalents.
• Government legal counsel — representing the government itself in civil matters: state attorneys general, county counsel, city attorneys, and agency general counsel.
• Public defense — representing indigent defendants (those who cannot afford a lawyer), a duty the federal industry definition places in this code alongside prosecution.[1]
• Supporting work: appeals, legal research, discovery, investigations, and case administration.

The industry is organized around federal, state, county, and municipal jurisdictions. Offices operate as budget-funded departments, not profit-seeking companies.

What it explicitly excludes (adjacent NAICS codes an investor should not conflate):

• 922110 Courts — the judges and courthouses themselves.
• 922120 Police Protection, 922140 Correctional Institutions (prisons/jails), 922150 Parole and Probation, and 922190 Other Justice, Public Order, and Safety Activities.[1]
• 5411 Legal Services — the entire private practice of law: 541110 Offices of Lawyers (including private criminal practices and legal-aid offices) and 541199 other legal/paralegal services such as process serving and patent-agent work. This is the for-profit counterpart and a completely separate, much larger industry.[2]

Ownership mix. Effectively 100% government. There are no private-equity owners or public shareholders of the core offices, and no shares, revenue, or profit. Private attorneys, nonprofits, and contract lawyers may deliver appointed prosecution or indigent-defense work under contract, but they are adjacent to — not owners of — the government establishment.

3. How big it is

Important data caveat. The federal business statistics we normally lean on do not cleanly cover this code. Census business programs (County Business Patterns, the Economic Census, and the SBA's small-business tallies) largely exclude Public Administration (NAICS sector 92) because government offices aren't counted as "firms" with "receipts." The Bureau of Labor Statistics ("BLS") likewise notes that its Quarterly Census of Employment and Wages private-ownership series does not represent Public Administration, which is governmental by nature.[3] Our own ingested federal dataset returns no business metrics for 922130 — expected and honest for a government function, not a gap to paper over. So there is no reliable national establishment count, revenue figure, or wage total specific to this code, and we do not substitute a suppressed value. The real yardsticks come from the Bureau of Justice Statistics ("BJS"), the Executive Office for U.S. Attorneys, and BLS occupational data — which measure offices, staff, caseloads, and public spending rather than companies and sales.

What those sources show:

• State prosecution. BJS counted 2,347 state prosecutor offices in 2020, employing more than 35,000 attorneys plus roughly 44,000 full-time non-attorney staff (investigators, victim/witness advocates, support) and reporting more than $6 billion in combined operating budgets.[4] That is on the order of 80,000 people in state prosecution alone.
• Federal prosecution. 94 U.S. Attorney offices, staffed by thousands of assistant U.S. attorneys ("AUSAs") and support personnel. In fiscal year 2024 they reported 52,469 criminal cases filed, 51,564 terminated, and 76,776 pending at year-end — federal district-court criminal workload only.[5]
• Public defense. BJS's Census of Public Defender Offices identified roughly 1,000 state- and county-funded public defender offices; the last full count dates to 2007 and a 2024 redesign pilot excluded offices staffed only by independent-contractor attorneys and found many lacked complete rosters, so current staffing figures are thin.[6]
• Government civil counsel. 50 state attorneys general plus thousands of county counsel and city attorney offices — no single clean federal headcount exists.
• Occupational context. BLS counted about 864,800 lawyer jobs across all industries in 2024. By employer, roughly 19% of lawyers work in government (local ~8%, state ~6%, federal ~5%), versus ~51% in private legal services and ~12% self-employed — a reminder that government is a meaningful but minority employer of lawyers, and these buckets do not isolate prosecution or public defense.[7]

Spending (the money that actually flows). Total U.S. justice-system spending — police, courts/legal, and corrections combined — was about $305 billion in 2017, up 62% in real terms since 1997.[8] Within that, the "judicial and legal" slice (courts plus prosecution and public defense) run by state and local governments was about $52 billion in 2021, roughly 21% of criminal-justice spending; the federal government spent an additional ~$15 billion on courts in 2017.[8][9] Prosecution specifically is a smaller piece: in just 58 large cities, prosecution budgets totaled about $2.6 billion in 2021.[10]

No single federal number isolates NAICS 922130 cleanly, because official spending buckets combine courts, prosecution, and defense. The honest summary: prosecution and government legal counsel are a multi-billion-dollar, tax-funded function employing well over 100,000 people, growing roughly with government budgets and case volumes.

For contrast, the excluded private legal-services industry (NAICS 5411) had revenue on the order of $300 billion and over 1 million employees[2] — the for-profit legal economy dwarfs the government-prosecution slice.

4. The investable universe

There is no pure-play public or private company whose principal business is NAICS 922130 — you cannot buy equity in a DA's office. The investable exposure is entirely indirect: vendors and service providers that sell into these offices, plus the private legal-services sector that mirrors the function. None of the companies below is a pure play; each earns only a portion of revenue from government legal/justice buyers.

Public-market proxies:

Private owners and adjacent platforms:

• The private legal-services industry (NAICS 5411) — roughly 191,000 firms and ~1.1 million employees — is the for-profit counterpart; law firms are overwhelmingly lawyer-owned partnerships, not listed equities.[2] The American Bar Association's Model Rule 5.4 restricts nonlawyer ownership, fee-sharing, and control of legal practices, which is why private capital tends to sit in software, staffing, administration, or "managed services organization" (MSO) structures rather than in firms that actually practice law; a few jurisdictions permit "alternative business structures" (ABSs).[13]
• A small set of listed litigation-finance names (e.g., Burford Capital) offer exposure to private litigation economics — but not to government prosecution.

5. How the money works

For the government function itself, "how owners make money" doesn't apply — there are no owners and no profit. The right lens is government budgeting for the offices, and vendor/provider unit economics for the investable layer.

The government side — appropriations, not revenue. A prosecutor's or defender's office is funded by an annual appropriation from a county board, state legislature, or Congress, plus dedicated fees, grants, and payments for appointed counsel. Its "output" is cases charged and disposed; its cost drivers are attorney headcount (salaries dominate), caseload, and, increasingly, the volume of digital evidence per case (body-camera footage, phone extractions, video) that must be stored, processed, and disclosed. The operating metrics that matter are budget per attorney and per case, caseload per lawyer, vacancies/turnover, backlog and time-to-disposition, and outside-counsel spend.

Labor is the dominant input, and wages are set by public pay scales, not margins: the median annual wage for lawyers was $151,160 in May 2024 — $174,680 in the federal government, $125,180 in local government, and $111,280 in state government (occupational wage measures, not 922130 profitability).[7]

The single most investable feature of this function is a structural imbalance: prosecution is generally far better funded than public defense. Indigent-defense systems have been chronically under-resourced for decades relative to prosecutors,[11] and federal defender services have repeatedly hit funding cliffs — in mid-2025 the courts briefly ran out of money to pay court-appointed (Criminal Justice Act, "CJA") panel attorneys.[12] For investors, that asymmetry is a demand signal: catch-up spending on the defense side is a plausible growth vector.

The vendor/provider side — this is where profit lives. Companies serving 922130 make money the way enterprise-software and legal-services firms do:

• Recurring subscription / software-as-a-service ("SaaS") revenue, often multi-year with high renewal rates. Tyler, for instance, reports ~$2 billion in annual recurring revenue.[15]
• Per-seat or per-case licensing, plus data-storage and processing fees that scale with digital-evidence volume — a tailwind as every case generates more video and device data.
• Implementation and integration services up front, then sticky maintenance.
• Services businesses — ALSPs, e-discovery, and staffing firms bill by matter, document volume, project, or managed-service contract.
• High switching costs. Once a court/prosecutor case-management system is the system of record, ripping it out is painful — which is why incumbents like Tyler and Karpel hold long-tenured accounts.

The catch is the sales cycle: government procurement is slow, budget-gated, and bid-driven. Revenue is durable but lumpy, and pricing is constrained by public budgets.

6. What drives demand

• Constitutional requirements. The Sixth Amendment right to counsel (established in Gideon v. Wainwright) obliges governments to fund public defense in cases that can result in imprisonment; that creates non-discretionary, recurring demand for defenders, assigned counsel, and contract attorneys.
• Government workload. Criminal enforcement, civil litigation, regulatory and public-integrity matters, appeals, and immigration all generate case volume — and with it, software seats, evidence storage, and forensic exams.
• Digital-evidence explosion. Body cameras, cell phones, CCTV, and cloud data have turned each case into a data-management problem. This is the biggest single driver of vendor demand — storage, redaction, and disclosure tooling scale with data volume, not just case count.
• Government budgets and tax receipts. Because this is appropriation-funded, demand tracks state/local fiscal health. Strong tax years fund hiring and system upgrades; recessions squeeze them.
• Technology modernization and reform. E-filing mandates, discovery/disclosure reforms (e.g., "open-file" and speedy-disclosure rules), cloud migration, analytics, and artificial intelligence ("AI") force technology purchases.
• Staffing shortages. BLS projects lawyer employment to grow ~4% from 2024 to 2034, with roughly 31,500 openings a year (largely replacement) — an occupation-wide figure, not a 922130 forecast.[7] Recruitment and retention problems on both sides push offices toward automation to do more with fewer lawyers.

7. Regulation

Because it is government, and because legal work is a licensed profession, this industry is defined by law rather than overseen by a single outside regulator:

• Constitutional floor. The Sixth Amendment right to counsel (Gideon) and prosecutorial disclosure duties (Brady v. Maryland), plus bar ethics rules, are in effect the industry's binding "regulations."
• Licensing and professional conduct. State supreme courts and bar authorities control lawyer admission, discipline, and continuing education; prosecutors and defenders must observe conflicts, confidentiality, and professional-conduct standards.
• Budget, procurement, and records law. Appropriations set the size of every office; competitive-bidding and sole-source rules shape how and when vendors can sell; public-records and retention rules govern the files.
• Data, privacy, and evidence rules. Chain-of-custody, the FBI's Criminal Justice Information Services ("CJIS") security policy, and discovery rules dictate how evidence software must handle data — a compliance moat favoring already-certified specialist vendors.
• Nonlawyer-ownership limits. ABA Model Rule 5.4 restricts nonlawyer ownership and control of law practices, steering private capital toward software/services rather than practicing firms.[13]
• AI use. ABA Formal Opinion 512 (2024) requires lawyers using generative AI to address competence, confidentiality, supervision, candor to tribunals, client communication, and reasonable fees.[14]

The regulatory opportunity is uneven: a vendor can sell workflow software broadly, while a business providing actual legal representation faces licensing, ownership, fee-sharing, and unauthorized-practice restrictions in each jurisdiction.

8. Competitive dynamics and consolidation

Within the government function there is no conventional competition — offices have jurisdictional responsibility, not a choice of customers. They compete only for qualified attorneys, public funding, contract-counsel panels, technology budgets, and better case outcomes. The commercial action is entirely on the vendor/provider side, and it is consolidating:

• Incumbency and scale win. Tyler Technologies is the dominant courts-and-justice platform and Karpel the dominant prosecutor-specific system; both benefit from switching costs and integration lock-in.[15][22]
• Private equity is rolling up the specialists. The 2026 Thompson Street investment in Karpel, and PE ownership of Axiom (Permira), Epiq (OMERS), and Consilio (Stone Point/Aquiline), are the template — private capital consolidating niche justice-software and legal-services vendors, typically via software/staffing/MSO structures that sidestep lawyer-ownership limits.[22][23][24][25]
• Platform convergence. Evidence (Axon, Motorola, Cellebrite), research/AI (Thomson Reuters, RELX), and case management (Tyler, Karpel) increasingly integrate, and larger players are expanding across lanes — raising the odds of further M&A.
• A structural tension worth watching: as more of the justice workflow runs on a handful of private platforms, critics have flagged concentration and "privatization of the court record" concerns[26] — a reputational and political risk for dominant vendors.

9. Risks

• No direct exposure. For anyone hoping to "invest in prosecution," there is nothing to buy; all exposure is diluted through diversified vendors and service firms.
• Fiscal and political risk. Government IT and staffing spending is discretionary and gets cut when tax receipts fall; charging reforms, decarceration, or surveillance pushback can raise or lower case volumes and reshape what tools offices may buy.
• Long, unpredictable sales cycles. Procurement delays make vendor revenue lumpy, and government contracts can be concentrated among a few large customers.
• Labor and constitutional risk. Attorney shortages, burnout, and low public pay reduce capacity; understaffed defense systems can produce ineffective-assistance claims, reversals, and civil litigation.
• Data and cybersecurity risk. Case files hold privileged, personal, financial, medical, and law-enforcement data — a serious breach exposure for any vendor.
• AI reliability risk. Hallucinated authorities, inaccurate summaries, and weak human review can create sanctions and malpractice exposure.[14]
• Public-defense funding fragility. Repeated federal and state funding cliffs make the defense-side buyer unreliable even where demand is obvious.[12]
• Fragmentation and measurement opacity. Fifty state systems, thousands of local jurisdictions, and sparse, dated federal statistics (the last full public-defender census predates 2010) complicate national scaling and make the end-market hard to size.[6]

10. How to invest and the outlook

Public routes. The cleanest listed exposure is the GovTech and legal-information vendors in Section 4 — Tyler Technologies (courts/justice software), Axon and Cellebrite (digital evidence and forensics), and Thomson Reuters / RELX (legal research and investigative data). Treat each as a diversified business with some government-legal revenue, not a pure play; tickers, valuations, and yields belong to the broader software/GovTech thesis, not to prosecution as such. Municipal bonds provide credit exposure to a government issuer, not ownership of a prosecutor's or defender's office.

Private routes. Private equity is the natural owner here — specialist justice software (the Karpel model), e-discovery and legal administration (Epiq, Consilio), on-demand legal talent (Axiom), ALSPs, and MSO infrastructure. The private legal-services industry (NAICS 5411) offers separate, much larger exposure to the for-profit practice of law, and litigation-finance vehicles offer exposure to private litigation economics — but neither is prosecution. Diligence should verify recurring-revenue share and renewals, government-contract concentration, data security, lawyer-ownership/conflicts compliance, and labor utilization.

Near-term drivers (forward-looking judgment, not fact):

• The digital-evidence data explosion looks like the most durable tailwind — every case keeps generating more video and device data that must be stored, redacted, and disclosed, favoring storage- and processing-priced software.
• Public-defense funding catch-up, if it materializes after recent funding crises, would broaden the buyer base beyond the better-funded prosecution side.
• Continued PE consolidation of niche justice-software and legal-services vendors is likely, creating exits for private investors and pricing power for winners.
• The main brake is government budget health: this end-market rises and falls with state and local tax receipts, so read the outlook as steady, appropriation-gated growth rather than a high-beta cycle.

Bottom line: NAICS 922130 is a government function, not a market — but the money it spends underwrites a real, consolidating, mostly-private vendor-and-services ecosystem, and that ecosystem is where investment exposure lives.
