Accommodation and Food Services (U.S.) — NAICS 72

A Histometrics rollup primer for a general investing audience. Relevant to both public-market and private investors.

NAICS 2022 code 72. NAICS — the North American Industry Classification System — is the nested code set the U.S. government uses to sort businesses by their main activity. This page covers the two-digit sector 72, Accommodation and Food Services: the top level of the "hospitality" economy — what Americans and visitors to America spend when they are away from home on a bed and a meal. It rolls up just two three-digit children: 721 Accommodation (lodging) and 722 Food Services and Drinking Places (eating and drinking out). Bracketed numbers like [1] point to the numbered Sources list at the end. Company-level detail lives in the two child primers and their children; this page rolls them up and, above all, contrasts them.


1. Overview

Sector 72 is one of the largest consumer sectors in the U.S. economy: roughly $1.20 trillion in receipts (revenue), about 784,900 employer locations, and 14.6 million paid workers — more than one in ten U.S. private-sector jobs, and among the largest employing sectors in the country.[1] It is the commercial core of what people loosely call "hospitality" (a slightly broader statistical grouping also folds in arts, entertainment, and recreation). Everything in it rests on the same durable habit: Americans increasingly sleep, eat, and drink somewhere other than their own home.

The sector has only two children, and for an investor the single most useful fact about this level is how unlike they are:

  • Accommodation (721) — hotels, motels, resorts, casino hotels, RV (recreational vehicle) parks, camps, dormitories, and workers' camps — is about a quarter of the sector's receipts but only ~13% of its jobs. It is capital-intensive: a room-night is sold out of an expensive building.
  • Food Services and Drinking Places (722) — every restaurant, drive-thru, coffee counter, caterer, food truck, and bar — is the other ~75% of receipts and ~87% of the jobs. It is labor-intensive: a meal is served by hand.

The distinctive thing about 72 as a level is what that contrast reveals: the sector's money and its jobs live in different children. Food services carries three-quarters of the dollars but nearly nine in ten of the workers; accommodation carries a quarter of the dollars on barely a tenth of the payroll, because it earns roughly twice the revenue per worker. A hotel is a real-estate machine; a restaurant is a labor machine. Ownership and how you invest diverge just as sharply — and, in the sector's central irony, the deepest pool of listed equity value sits in the smaller child (hotel brands, casino operators, and their landlords), while the larger child is a fragmented ocean of independents with only two narrow public doors. The rest of this page is built around that contrast.[2][3]


2. What's inside — the two children, and how they differ

The comparison below is the heart of this page. Read it top to bottom before the section detail; every later section elaborates one of these rows.

Dimension 721 — Accommodation 722 — Food Services & Drinking Places
What it is Hotels, motels, resorts, casino hotels, B&B inns; RV parks & campgrounds; recreational camps; dormitories, rooming houses & workers' camps[2] Full- and limited-service restaurants, coffee/snack bars, buffets; caterers, contract/cafeteria feeding, food trucks; bars, taverns & nightclubs[3]
What's sold A room-night — time-bound occupancy of a physical unit A meal or a drink — food and beverage prepared and served away from home
Share of receipts (2022) ~$295.7B (~25%)[2] ~$900.6B (~75%)[3]
Share of locations (2023) 70,350 (~9%)[2] 714,532 (~91%)[3]
Share of jobs (2023) 1,963,343 (~13%)[2] 12,644,827 (~87%)[3]
Revenue per location (rough gauge) ~$4.2M — capital-heavy, revenue-dense ~$1.3M — many small units
Revenue per worker (rough gauge) ~$151k — the real-estate machine ~$71k — the labor machine
Market structure (CR4 / HHI) Fragmented but the more concentrated child — CR4 16.4%, HHI 98.9[2] Near-atomized — CR4 5.7%, HHI 13.1[3]
Direction of travel Large, mature, cash-generative; low-single-digit room-rate growth; consolidating on the brand and casino sides Mature; modest real growth; harbors both the sector's clearest structural grower (contract caterers) and its one secular decliner (bars)
Cyclical or defensive More cyclical — big-ticket, deferrable travel; leisure- and gaming-led Stickier — routine, frequent, small-ticket eating; institutional feeding is the most defensive pocket of all
Who owns them Asset-light brands, hotel REITs, casino operators, gaming REITs (all public) + tens of thousands of private franchisees; tribal casinos, mom-and-pop parks, universities, nonprofits (not investable) Overwhelmingly independent single-venue small businesses + concentrated brands (many biggest ones private); three global contract-catering giants are the lone oligopoly
Public pure-play? Deepest listed value in the sector — but no vehicle is a pure play on "accommodation" Deepest listed menu of operators (restaurants) + the only clean pure-plays (contract caterers, mostly abroad); nothing clean in bars
How to invest Brand stocks, hotel REITs, casino operators, gaming REITs; or private hotel/park ownership Restaurant franchisors & operators, contract caterers; or private ownership of restaurants, caterers, trucks, bars

(REIT = real estate investment trust, a company that owns income property and passes most of its income to shareholders as dividends. CR4 = combined revenue share of the four largest firms. HHI = the Herfindahl-Hirschman Index, a 0-to-10,000 concentration score where higher is more concentrated; U.S. antitrust agencies treat 1,500 as the "moderately concentrated" line. B&B = bed-and-breakfast. Revenue-per-location and per-worker mix 2022 receipts with 2023 counts, so read them as rough scale gauges, not precise ratios.)

The three insights the rollup reveals:

  1. The money and the jobs sit in different children. Food services is ~75% of the dollars but ~87% of the jobs; accommodation is ~25% of the dollars on only ~13% of the jobs, because a hotel earns about twice the revenue per worker of a restaurant. The sector's cash concentrates where the buildings are; its employment concentrates where the hands are. Any statement about "sector 72" blends a capital-intensive real-estate business with a labor-intensive service business.[2][3]

  2. The deepest listed value is in the smaller child — but there is no pure play anywhere. Public-market equity value is deepest in hotels, casinos, and their landlords (accommodation), while the far larger food-services child is mostly private independents with only two public doors (restaurant franchisors and contract caterers). Neither child, and certainly not the sector, offers a single vehicle that is the industry.[2][3]

  3. The sector looks perfectly competitive but hides concentrated pockets. The headline four-firm share is just 5.4%lower than either child — because the biggest hotel firm is not the biggest restaurant firm is not the biggest caterer, so combining the children spreads the leaders across a bigger base. That near-zero reading conceals real concentration inside: hotel brands and casinos (721), and the contract-catering oligopoly buried inside 722 (Section 8).[1][2][3]

A shared boundary to remember. Sector 72 is the service of lodging and of prepared food and drink, and nothing else. It excludes: standalone casinos and gambling with no hotel (NAICS 713, even though casino hotels sit inside 721); most whole-home short-term rentals such as many Airbnb/Vrbo listings (STRs — short-term rentals — classify to residential leasing, 531110); self-operated institutional dining run in-house by schools, hospitals, and companies (tallied under education, health care, or manufacturing, not here); on-campus university housing and government campgrounds (education and government codes); and grocery, packaged-food retail, and food manufacturing (separate sectors). What ties the two children together is the away-from-home occasion: a single trip generates a room-night in 721 and several meals out in 722, they co-locate (hotel restaurants, resort dining, casino buffets), and they share one demand engine and one cost base — which is exactly why the government files them as one sector.[4]


3. How big it is (the rollup)

Our ground-truth federal statistics for NAICS 72 come from two U.S. Census Bureau programs, and note the mixed vintages: receipts, firm counts, and concentration are the 2022 Economic Census (EC); establishments, employment, and payroll are 2023 County Business Patterns (CBP), the Bureau's annual count of employer businesses. Treat this as a profile, not a single-year income statement, and do not divide across the two datasets to manufacture a precise margin figure.[1]

Metric Value Source (year)
Receipts (revenue) ~$1,196.32 billion Economic Census (2022) [1]
Firms (distinct companies) 574,892 Economic Census (2022) [1]
Establishments (locations) 784,882 County Business Patterns (2023) [1]
Employment 14,608,170 County Business Patterns (2023) [1]
Annual payroll ~$393.17 billion County Business Patterns (2023) [1]
First-quarter payroll ~$93.70 billion County Business Patterns (2023) [1]
Concentration — CR4 / CR8 / CR20 / CR50 5.4% / 8.4% / 13.3% / 18.8% Economic Census (2022) [1]
Herfindahl-Hirschman Index (HHI) 13.2 (near the floor) Economic Census (2022) [1]

The rollup reconciles cleanly with its two children. Receipts, establishments, employment, and payroll all sum to these totals within rounding — receipts to the dollar ($295.698B + $900.618B = $1,196.316B), establishments and employment exactly (70,350 + 714,532 = 784,882; 1,963,343 + 12,644,827 = 14,608,170). The one figure that does not sum, and shouldn't, is firm count: the children total 575,213 firms against the sector's 574,892, because a company operating in both lodging and food service (a resort group that also runs restaurants, say) is counted once in each child but only once here.[2][3]

Two quick reads, and one warning. Averaged across the whole sector, an employer location turns over about $1.5 million a year, employs about 19 people, and pays about $26,900 per worker — but every one of those averages is a fiction that blends a $147-million casino resort and a single food truck into one meaningless number, and the pay figure excludes tips, a large part of server and bartender take-home. First-quarter payroll runs at about 24% of the annual figure, the mild seasonal dip expected of leisure-facing businesses.[1]

Undercount caveat — the ~$1.2 trillion is a floor, and each child understates for its own reasons. Both datasets count only employer firms.

  • Accommodation (721) captures its dominant hotel-and-casino core well, but casino "receipts" bundle gambling winnings with rooms and food, the big brands' royalty and management-fee income books under separate corporate codes (so the brands' economic weight is larger than property receipts imply), and the small outdoor and group-housing fringes (nonemployer RV parks, nonprofit camps, government campgrounds, on-campus dorms) are excluded.[2]
  • Food services (722) understates most through self-operated institutional dining (schools, hospitals, and employers that run their own cafeterias, tallied under other sectors), the nonemployer tail of one-person restaurants and caterers, and on-premise drinking that happens inside hotels, casinos, and arenas counted elsewhere.[3]

Both receipts figures are 2022 and predate recent menu-price and room-rate inflation, so current sales are higher; for scale, the National Restaurant Association pegs the entire U.S. restaurant-and-foodservice industry at roughly $1.5 trillion in 2025.[8] The federal file also does not publish, at this level, industry-wide margins, growth rates, or a public/private ownership split — so we do not state them; company figures in later sections come from filings and trade data, labeled as such, and no confidentiality-suppressed value is used anywhere on this page.

Bottom line: read the ~$1.2 trillion as a solid measure of the employer hospitality economy — dependable for the hotel and restaurant cores that dominate it, and a conservative floor for the self-operated, nonemployer, government, and nonprofit edges it only partly sees.


4. Investable universe — where value concentrates across the children

For a public-market investor, value in sector 72 concentrates in three doors across the two children, and there is no pure-play vehicle for the sector as a whole. We reserve tickers for this section and Section 10.

  • Accommodation (721) — the deepest value, through four kinds of listed vehicle. Asset-light hotel brand companies (franchisors that license the name and loyalty system and collect fees) hold the largest public-market values in the whole sector; alongside them sit hotel REITs (owning the buildings), casino operators, and gaming REITs (owning and leasing back the resorts). The catch: no listed company is "accommodation" — each is a slice, and the two small outdoor and group-housing children offer only narrow, segment-level windows (two manufactured-housing/RV REITs; a handful of workforce-lodging small-caps).[2][5]
  • Restaurants (inside 722) — the deepest menu of operators. This is where most listed food-services equity lives: franchise-royalty compounders (asset-light brand owners collecting a royalty on franchisees' sales), company-operated growth chains, large full-service operators, and a short snack-and-beverage list. But the biggest brands are often private (Chick-fil-A, In-N-Out, Raising Cane's cannot be bought on any exchange), and where franchising dominates the public "company" is the brand owner collecting royalties, not the restaurants.[3]
  • Contract catering (inside 722) — the only clean pure-plays, mostly abroad. Three global contract-foodservice giants plus a couple of smaller specialists are the sector's lone genuine pure-plays and its only real operator-level oligopoly — but the cleanest names list in London and Paris. Caterers, food trucks, and bars have essentially no public pure-play of scale.[3]

The synthesis: public dollars have effectively three doors — hotels/casinos/landlords (721), the broad restaurant menu, and the narrow contract-catering pure-plays (both inside 722) — each with its own economics and cycle. No fund, ETF (exchange-traded fund), or company is a pure play on "Accommodation and Food Services." Sizing any single vehicle as "the hospitality sector" overstates what you actually own. Private dollars, by contrast, have doors into every corner (Section 10).


5. How the money works

Every business in the sector sells a perishable, time-bound service out of a fixed location — an empty room-night or an unsold table cannot be stored and resold tomorrow — and all of them carry high fixed costs and high operating leverage: the building, rent, taxes, insurance, and core staff must be paid whether the place is half-full or full, so profits swing hard with occupancy and traffic. That shared skeleton is the root of the sector's cyclicality. On top of it, the two children earn in structurally different ways:

  • Accommodation (721) sells the room. Hotels are watched on the yield trio — occupancy, ADR (average daily rate, room revenue ÷ rooms sold), and RevPAR (revenue per available room = occupancy × ADR, the headline efficiency measure, about $99.94 at ~63% occupancy in 2024).[6] Economics split along a brand / owner / operator line: brands earn capital-light royalty and management fees that hold up in downturns; owners and REITs ride the full property cycle on net operating income (NOI) and funds from operations (FFO, the standard REIT cash-earnings measure); casino hotels add a gaming stream measured on the house edge and are judged on EBITDAR (earnings before interest, taxes, depreciation, amortization, and rent) because many sold their real estate to gaming REITs.[5]
  • Food services (722) sells the meal. The whole child runs on prime cost — food plus labor combined, the number that matters more than store count. Restaurants earn on guest visits × average check, split on operator-vs-franchisor lines (a company-operated unit keeps the whole sales dollar at thin single-digit margins; a franchisor collects a high-margin ~4–6% royalty on franchisees' sales). Contract caterers earn on procurement scale and contract mechanics; bars earn on the spread between a drink's pour cost (~18–24%) and its price. The most-watched restaurant metric is same-store (comparable) sales, split into traffic vs. check.[3]

The cross-cutting synthesis: in both children, the most durable, capital-light profit is collected not by the operator but one layer up — by the asset-light brand/franchisor layer (hotel brands, restaurant franchisors) and the landlord layer (hotel REITs, gaming REITs, commissaries, ground leases), plus the distribution middlemen (online travel agencies, or OTAs, that take a standing cut of hotel bookings; delivery platforms that take a cut of restaurant orders). The operators who actually run the rooms and kitchens bear the full cost and cycle. For diligence anywhere in the sector, watch utilization (occupancy or table turns), prime cost / labor, and fixed-cost coverage — not headline system sales.


6. Demand drivers

Both children are discretionary "away-from-home" spending, so the sector tracks the broad consumer — employment, wages, confidence — and is sensitive to interest rates (which drive both new supply and financing costs). On that shared base, the engines and their defensiveness differ:

  • Accommodation (721) rides travel and tourism: leisure and business trips, meetings and conventions, inbound international visitation, and — for casinos — regional gambling and the migration of betting onto phones (both an opportunity and a substitution threat). It is the more cyclical child because a trip is a big-ticket purchase that can be deferred.[6]
  • Food services (722) rides one of the economy's most durable habits: eating and drinking food someone else prepared. Food-away-from-home spending reached roughly $1.52 trillion in 2024, about 59% of the U.S. food dollar — a share that has trended up for decades.[7] It is stickier because eating out is routine and frequent, and it contains the sector's most defensive pocket (daily institutional feeding by contract caterers) and its one secular decliner (bars, as U.S. drinking participation fell to a record-low ~54% of adults in 2025).[8][9]

The cross-cutting judgment: the two children rhyme but do not move in lockstep. They peak together in a strong travel-and-consumer year and both collapsed overnight in 2020, but accommodation is the more volatile, leisure-led swing while food services is the steadier, habit-led base — so the sector as a whole is somewhat less cyclical than its lodging child alone, and somewhat more cyclical than restaurants alone.


7. Regulation

There is no single federal regulator for sector 72; it is governed as local real estate and public accommodations, layered with federal labor and food-safety overlays, plus two segment heavyweights (gaming and alcohol). A common federal spine runs under essentially every business in the sector:

  • Accessibility — the Americans with Disabilities Act (ADA) governs public accommodations across lodging and dining.
  • Labor — the Fair Labor Standards Act (FLSA), including the tip credit (a $7.25 federal wage floor, a $2.13 tipped cash wage) that shapes pay in both hotels and restaurants, on top of state wage mandates.
  • Food safety — the FDA (Food and Drug Administration) model Food Code, plus local health inspections, wherever food is served.
  • Franchising — the FTC (Federal Trade Commission) Franchise Rule and its Franchise Disclosure Document, which governs both hotel brands and restaurant brands, since both children franchise heavily.
  • Local taxes — state and local occupancy ("bed") taxes on rooms and sales/excise taxes on meals and drinks, the levies that touch nearly every location.[10]

On top of that spine, each child carries its own heavyweight layer: casino hotels are among the most regulated consumer businesses in the country (state and tribal gaming regulators, the federal Indian Gaming Regulatory Act, and anti-money-laundering rules under the Bank Secrecy Act that treat casinos as financial institutions), while drinking places face the nation's tightest consumer-product regime (the federal Alcohol and Tobacco Tax and Trade Bureau, the state three-tier system, quota-limited liquor licenses, and dram-shop liability). Smaller layers govern the fringes — child-protection rules for camps, the temporary-labor-camp standard for workers' camps, and locally charged mobile-vending permits for food trucks.[10] For the concentrated top (contract caterers, casinos) regulation is largely a barrier to entry that protects incumbents; for the fragmented base it is a fixed setup cost every operator clears.


8. Consolidation

Federal concentration data for the whole sector (2022) show it is broad and unconcentrated: the four largest firms held 5.4% of receipts, the top fifty just 18.8%, and the HHI is only 13.2 — near the theoretical floor, far below the ~1,500 "moderately concentrated" line.[1]

The revealing point is that the sector's top-4 share (5.4%) is lower than either child (721's 16.4% and 722's 5.7%).[2][3] That is because the largest companies specialize by subsector — the biggest hotel firm is not the biggest restaurant firm is not the biggest caterer — so combining lodging and food service spreads the leaders across a far larger base and dilutes measured concentration. It is a genuine sign of breadth, not a data artifact, and the sector HHI sits near the floor because the atomized food-services child, which sets three-quarters of the revenue base, drags the blend down.

But the near-zero headline hides the concentrated pockets, and consolidation runs on distinct tracks:

  • In accommodation (721): a brand-side M&A story (Marriott–Starwood; a pending ~$17.6B take-private of Caesars announced in 2026) plus a sale-leaseback wave moving casino real estate to gaming REITs, while property ownership stays fragmented and institutional capital rolls up under-managed RV parks.[2]
  • In food services (722): the sector's only real operator-level oligopoly — the contract caterers — grows by converting self-operated accounts and acquiring regional players, alongside private-equity roll-ups of restaurant franchisors (buying capital-light royalty streams), while the independent restaurant and bar base stays durably atomized.[3]

So the true competitive picture is a giant atomized base of independents and franchisees, with concentrated brands on top of hotels and restaurants and one genuine acquisition-led caterer oligopoly tucked inside — three concentration regimes the single sector HHI flattens into one near-zero number.


9. Risks

Shared across the sector:

  • Cyclicality and operating leverage — the master risk: discretionary demand plus high fixed costs magnify downturns, and 2020 showed the tail (both children shut off almost overnight).
  • Cost inflation — labor, food, energy, insurance, and property taxes, plus recurring capital demands (renovations, brand-mandated property-improvement plans), often outrunning achievable price and rate increases against thin operator margins.
  • Consumer trade-down and traffic erosion after years of price increases.
  • Data opacity — employer-only federal figures miss the nonemployer, self-operated, government, and nonprofit fringe, bundle casino gaming into "lodging" receipts, and exclude hotel-brand fee income; no single source gives a complete read.

Where the risk profiles split:

  • Accommodation (721): interest-rate and refinancing risk for leveraged hotel and casino owners and every REIT type; casino hold volatility and digital-betting substitution; child-safety liability at camps; and climate and insurance strain on coastal, wildfire-, and storm-exposed properties.[2]
  • Food services (722): a margin-pressuring value war in limited-service, punishing third-party delivery economics, a GLP-1 weight-loss-drug headwind to per-person consumption, the secular decline in drinking (the biggest structural risk in the child), and currency/liquidity considerations because the cleanest caterer pure-plays list abroad.[3]

The most dangerous combination anywhere in the sector is the same: falling occupancy or traffic against fixed rent, debt, and labor commitments. Full risk registers are in each child primer.


10. How to invest, and the outlook

Match the route to the child, and value each on its own model. There is no clean pure-play index for sector 72; broad consumer-discretionary, travel-and-leisure, restaurant, gaming, and REIT ETFs each give only diluted, partial exposure. A public position is built through three doors:

  1. Accommodation (721): brand/franchisor stocks for capital-light fee exposure, hotel REITs for the property cycle plus dividends, casino operators for levered gambling-and-travel exposure, or gaming REITs for a bond-like profile. (Tickers and the two small-child windows — manufactured-housing/RV REITs and workforce-lodging small-caps — are mapped in the 721 primer.)
  2. Restaurants (inside 722): franchise-royalty compounders for steadier capital-light exposure, company-operated growth chains for higher growth and volatility, and large full-service operators for scale and dividends — judged on same-store sales, average unit volume, restaurant-level margins, and franchise mix.
  3. Contract catering (inside 722): the sector's only clean pure-plays — best judged on contract-foodservice metrics (client retention, net new business, organic growth, cost pass-through), and remembering that the cleanest names list abroad, so U.S. buyers use ADRs (American Depositary Receipts, U.S.-traded proxies for foreign shares) and carry currency risk.

For a private investor, the sector is far richer, and access widens as the businesses get smaller. Own or develop a franchised hotel, an RV park, an independent restaurant, a caterer, a food truck, or a bar; back a private-equity roll-up or lend via private credit; or own the scarce assets underneath — real estate, liquor licenses, commissaries, concession and ground-lease rights. Underwrite the individual location's sustainable cash flow (four-wall for a restaurant, per-property for a hotel, venue-level for a bar), not headline system sales or federal totals. Start any single-name analysis with the company's annual report (the Form 10-K filed with the Securities and Exchange Commission for U.S. issuers), and never carry one child's yardstick onto the other — hotel RevPAR multiples do not belong on a restaurant, restaurant same-store-sales math does not describe a franchisor's royalty stream, and REIT dividend yields describe neither.

Outlook (forward-looking judgment). NAICS 72 is a large, mature, cash-generative, roughly-$1.2-trillion (2022; larger now) consumer sector whose center of gravity is the durable away-from-home habit — travel that fills rooms and the ~59% of the food dollar now spent eating out. Its base case is modest, largely inflation-led growth with cautious, value-seeking consumers and persistent cost pressure. What the rollup adds is that the marginal growth and diversification live in small pockets: workforce lodging's pivot toward infrastructure and AI (artificial intelligence) data-center construction and the institutional roll-up of RV parks (inside 721), plus the long outsourcing tailwind under contract catering (inside 722) — set against the secular decline of bars as the clearest structural drag. The external swing factors that cut across the whole sector are the cost of capital (which decides whether leveraged owners, REITs, and expansion survive), consumer health and the travel cycle, and the regulatory and cost tide (gaming and tax policy for casinos, alcohol law for bars, junk-fee and franchise rules for hotels and restaurants, and labor and food-safety costs everywhere). Net: a large, essential, unforgiving consumer sector whose federal totals blur a capital-intensive real-estate business (lodging) with a labor-intensive service business (food) — read both child primers before committing capital to any single piece. Forward views here are judgments, not guarantees.
