All Other Amusement and Recreation Industries (U.S.) — NAICS 713990

A Histometrics industry primer for public-market and private investors.

1. Overview

NAICS (North American Industry Classification System) code 713990 is the government's catch-all bucket for hands-on recreation that does not fit any of the named amusement categories. It covers operators of miniature golf courses and driving ranges, trampoline and indoor-adventure parks, escape rooms, laser tag, go-kart tracks, batting cages, billiard halls, riding stables, archery and shooting ranges, whitewater-rafting and zip-line outfitters, hot-air-balloon and other guide services, recreational day camps, and amateur or youth sports clubs that field teams without owning a facility.[1]

Why it matters to an investor: this is a piece of the "experience economy." Consumers keep shifting spending from goods toward things they can do, and a lot of that money lands in exactly these local, physical venues. But the sector is unusually hard to own through the stock market. It is dominated by small, private, often single-location businesses, and the handful of larger brands are mostly franchised or private-equity-backed. The clearest public-market touchpoint of recent years, Topgolf (high-tech driving ranges), has just moved out of public hands.[12][13]

There is no single business model here. A driving range, a youth-sports club, an escape-room chain, and an outdoor-adventure outfitter have very different demand, cost, regulatory, and capital profiles — so subcategory selection, not "the recreation industry," is the real unit of analysis.

Practical ways in:

• Public markets (thin): a few small or partial-exposure equities and experiential real estate.
• Private (where the action is): venue ownership and franchising, plus private-equity and growth-capital roll-ups — especially in youth sports and family entertainment.
• Direct ownership of a single venue, which is how most operators in this code actually exist.

2. What it is and how it's structured

Scope. The Census Bureau defines 713990 as establishments primarily providing recreation and amusement services that are not classified elsewhere. Illustrative members: amusement-ride and coin/card-operated (non-gambling) device concession operators; outdoor adventure operations such as whitewater rafting without lodging; miniature golf and driving ranges; archery and shooting ranges; recreational (non-instructional) day camps; billiard and pool parlors; recreational chess or bridge clubs; boating clubs without marinas; youth and recreational sports clubs that field teams but run no facility; escape rooms; and riding stables (other than horse boarding).[1]

What it explicitly excludes — this matters, because the biggest, most familiar "fun" companies sit in adjacent codes, not here:

• Amusement and theme parks, and arcades — Industry Group 7131 (parks 713110; arcades 713120). Six Flags/Cedar Fair and Dave & Buster's live here.[1]
• Casinos and gambling — Industry Group 7132.[1]
• Golf courses and country clubs (except miniature) — 713910.[1]
• Skiing facilities — 713920 (e.g., Vail Resorts).[1]
• Marinas — 713930.[1]
• Fitness and recreational sports centers (gyms) — 713940.[1]
• Bowling centers — 713950 (Bowlero).[1]
• Resorts that combine recreation with lodging — Industry Group 7211 (accommodation).[1]

A single ride run at a fair or on a concession basis can fall in 713990, while a full amusement park generally does not. Standalone sports instruction is generally classified under education services, not here.

Ownership mix. The industry is overwhelmingly small and privately held. The 2022 Economic Census counted 20,938 employer firms generating $19.1 billion in receipts — roughly $0.9 million of revenue per firm — and County Business Patterns counted 22,786 establishments employing about 223,000 people, so a typical establishment has only ~10 workers.[2][3] The near-equality of firm and establishment counts is consistent with a predominantly single-location structure (the federal data do not publish a single-unit ownership percentage).[2][3] Franchising is the main way brands scale (trampoline/adventure parks, kids' enrichment); private equity is the main aggregator (youth-sports platforms, family-entertainment brands). Governments and nonprofits deliver a large parallel slice of the same activities — municipal parks-and-recreation programs, public pools, YMCA-type day camps — classified under government/nonprofit codes, not here.

3. How big it is

Core federal figures (U.S.):

Average pay of roughly $27,000 per worker reflects how seasonal, part-time, and entry-level much of the labor is (camp counselors, ride operators, ranch hands, guides).[3]

The undercount caveat — large here. The federal employer statistics above miss two big pieces of this industry:

1. Nonemployer businesses. Fishing and hunting guides, riding-stable owners, freelance ride/concession operators, and small outdoor outfitters are frequently sole proprietors with no payroll. They appear in the Census Bureau's separate Nonemployer Statistics program, not in the employer counts, so the true number of businesses in 713990 is materially higher than the ~22,800 employer establishments suggest.[5]
2. Government and nonprofit provision. A great deal of public-park programming, municipal pools, and community day camps is delivered by governments and nonprofits — government-owned establishments are outside Economic Census coverage and much of this activity is classified outside this code.[6]

The supplied federal data also do not report industrywide capacity utilization, average ticket, same-venue sales, unit-level EBITDA (earnings before interest, taxes, depreciation, and amortization), margins, or debt — those are venue-level, private figures.

Private data providers, using a broader and later-year definition that folds in nonemployers, put the category near $23.9 billion of revenue for 2026.[9] For scale context, the U.S. Bureau of Economic Analysis's Outdoor Recreation Satellite Account valued the entire outdoor-recreation economy at $696.7 billion, or 2.4% of GDP (gross domestic product), in 2024 — 713990 is a small, specific slice of that much larger activity.[7]

Concentration. This is one of the most fragmented industries in the economy. In 2022 the four largest firms held just 9.5% of receipts (CR4), the top eight 11.3% (CR8), the top 20 14.3%, and the top 50 only 18%.[2] (CRn = the combined revenue share of the n largest firms.) The Herfindahl-Hirschman Index (HHI), the standard single-number concentration score, is suppressed for this code and is not estimated here — but a CR50 of 18% signals a near-atomized market with no dominant player.[2]

4. The investable universe

There is no large-cap "pure play" on NAICS 713990, and the pool of public equities is thin. Treat this as a mostly private industry with a few partial public windows.

Public and listed exposure

Adjacent, listed, but NOT in 713990 (context only): amusement parks — Six Flags/Cedar Fair (FUN, 713110); arcades/eatertainment — Dave & Buster's (PLAY, 713120); bowling — Bowlero (BOWL, 713950). Screen any "leisure" stock by its actual primary activity, not its entertainment branding. Broad consumer-discretionary or leisure ETFs (exchange-traded funds) touch the theme only diffusely.

Major private owners and operators — where the industry actually consolidates:

• Topgolf. The most visible recent shift from public to private ownership: LGP controls ~60% (a deal valuing the stake around $1.1 billion), Callaway retains ~40%; ~92 U.S. venues and ~$1.8 billion of revenue.[12][13]
• Mini-golf / tech-golf concepts. Puttshack (technology-enabled mini golf; raised $150 million of growth capital from BlackRock-managed funds, with continued backing from Promethean Investments) and PopStroke (mini golf plus food, beverage, and social occasions) are leading privately held formats.[16][21]
• Trampoline / indoor-adventure parks. Sky Zone (formerly CircusTrix; now runs Sky Zone, DEFY, and Rockin' Jump, backed by Palladium Equity Partners) and Urban Air (350-plus parks open or in development) are the leading chains — company-operated and franchised.[17][18]
• Unleashed Brands. A franchising platform combining Urban Air with kids' enrichment brands (The Little Gym, Snapology, Class 101, Premier Martial Arts); 800-plus locations and $750 million-plus in systemwide sales, acquired by private-equity firm Seidler Equity Partners in 2023.[19]
• Five Star Parks & Attractions. A private-equity-backed family-entertainment-center consolidator; its venues mix mini golf with bowling, arcades, and other activities, some of which fall outside 713990.[20]
• Youth-sports platforms. Unrivaled Sports (backed by Josh Harris and David Blitzer; took a $120 million growth investment led by Dick's Sporting Goods in 2025 at a $650 million-plus valuation) and IMG Academy (bought by BPEA EQT for $1.25 billion) are the marquee private aggregators of clubs, tournaments, and complexes.[23]
• Herschend Family Entertainment. A large family-owned leisure operator, though much of its portfolio is amusement parks and attractions outside 713990.[22]
• Escape rooms, guide services, riding stables, go-kart/laser-tag venues. Almost entirely independent single-site operators or small local chains.

Private ownership is genuinely hard to measure: franchisor ownership, franchisee ownership, leased real estate, and operating contracts often sit in separate legal entities.

5. How the money works

Owners in 713990 run local, fixed-cost venues (or small mobile operations) that sell time, admissions, and add-ons — economics closer to hospitality and specialty retail than to any stock-market "sector." The levers that matter:

• Per-visit revenue and throughput. Money comes from tickets/admissions, per-hour or per-lane/per-bay pricing, memberships and season passes, birthday parties and group/corporate bookings, and high-margin add-ons (food and beverage, arcade/redemption games, retail, equipment rental, and — for trampoline parks — grip socks). Capacity is finite, so the core unit-economics metrics are revenue per available hour and utilization of bays/lanes/bookable slots by daypart, much as revenue per available room (RevPAR) works for hotels. For escape rooms, weekly bookings times average party price is essentially the whole model.[11]
• Fixed-cost operating leverage. Rent (or owned land), equipment, and a base staffing level are largely fixed; incremental visitors drop a large share to the bottom line, and empty capacity is pure loss. These businesses are profitable when busy and quickly unprofitable when foot traffic falls.
• Key operating measures. Same-venue sales, attendance, capacity utilization, average revenue per visit, food-and-beverage attachment, membership retention, group-booking volume, labor cost, rent, insurance, maintenance spend, and new-unit payback.
• Seasonality. Rafting, ballooning, riding, day camps, and driving ranges cluster revenue into good-weather months and school breaks, so annual results hinge on a few peak periods and the weather during them.
• Franchising economics. For the branded chains, the operating company's profit comes less from running venues and more from franchise/development fees plus ongoing royalties (a percentage of each franchisee's sales) — a capital-light, higher-margin layer on top of venue economics the franchisee bears. It shifts build-out and operating capital to franchisees, at the cost of less control over safety, service, and closures. Terms are disclosed in each brand's FDD (Franchise Disclosure Document).[17]
• Private-equity roll-up math. Aggregators buy many small operators at low single-location multiples, combine back-office, procurement, marketing, and scheduling, and aim to re-rate the whole platform at a higher multiple of EBITDA — the "buy small, professionalize, sell big" thesis driving youth-sports and family-entertainment deals.[23]
• Capital intensity and liability. Build-out (trampolines, ropes courses, karts, ride equipment) is real up-front capital, and insurance is a structural cost because many activities carry physical-injury risk (see Regulation and Risks).

6. What drives demand

• Discretionary income and the experience shift. These are discretionary outings; spending rises with consumer confidence and disposable income and gets cut early in downturns. The millennial and Gen Z preference for experiences over goods — amplified by social media and shareability — is a durable tailwind.[10]
• Families with children. Trampoline parks, kids' adventure venues, day camps, riding lessons, and birthday parties depend on household formation, school calendars, and parents' willingness to spend on children's activities.[19]
• The youth-sports arms race. Rising per-athlete household spending, year-round specialization, and travel-team culture have turned amateur/club sports into a $40 billion-plus ecosystem growing roughly 8-10% a year — the single biggest demand story touching this code.[23]
• Corporate and group events. Team outings, parties, and tourism bookings are a meaningful, higher-ticket revenue layer for many venue formats.
• Tourism and the outdoors. Rafting, zip-lines, guided fishing/hunting, and balloon rides ride destination and drive-to travel and the broader adventure-tourism market (U.S. estimated near $37.7 billion in 2025).[10] For scale, the Outdoor Industry Association counted 175.8 million U.S. outdoor participants in 2023 — 57.3% of the population it covers — though that is a participation indicator, not a 713990 market-size estimate.[8]
• Real-estate reuse. Vacant retail, industrial, and mixed-use space is frequently repurposed into indoor entertainment venues, lowering entry cost.
• Novelty and social sharing. Escape rooms, axe throwing, and new attraction formats can boom then plateau as novelty fades and local markets saturate, so operators continually refresh attractions to hold repeat visits.[11]

7. Regulation

There is no single federal regulator of this industry; oversight is a patchwork that varies by activity and, especially, by state and locality.

• Amusement rides and devices. Safety turns largely on the voluntary ASTM F24 standards (from ASTM International), which most operators follow for design, operation, inspection, and maintenance; the U.S. Consumer Product Safety Commission (CPSC) works with ASTM on these voluntary standards for amusement rides, trampoline parks, and adventure attractions. Roughly 35 states reference ASTM standards in their rules, but only about 20 have "comprehensive" oversight with mandatory inspections and accident-investigation authority; others are light-touch or lean on insurers.[24][25]
• A federal jurisdictional gap. The CPSC regulates mobile rides (traveling fairs and carnivals) but has no authority over fixed-site rides — a well-known regulatory gap that leaves permanent parks and venues to state and local regimes.[25]
• Workplace and accessibility. The Occupational Safety and Health Administration (OSHA) applies general workplace-safety rules to these operators.[26] The Americans with Disabilities Act (ADA) applies to public accommodations and sets accessibility requirements for recreation facilities, and — under the 2010 ADA Standards — for newly designed or altered amusement rides, miniature golf, golf facilities, and play areas.[27]
• Insurance and liability. Liability insurance is often mandatory (state ride rules commonly require coverage from $100,000 up to $1 million-plus per occurrence) and is a structural cost in any injury-prone activity. Liability waivers are widely used but do not shield an operator from liability for genuine safety failures, and their enforceability varies by state.[25]
• Activity-specific rules. Guided fishing/hunting and river outfitting need federal/state permits (public-land use, Coast Guard rules for some watercraft); shooting and archery ranges face firearms, noise, lead-exposure, and zoning rules; riding stables face animal-welfare and land-use rules; day camps face state camp-licensing, supervision, and background-check requirements; balloon and other air rides fall under Federal Aviation Administration (FAA) oversight.
• Local land use. Zoning, occupancy, noise, and building/fire codes are ever-present municipal constraints. State regimes can be material and specific — Ohio, for example, maintains a dedicated amusement-ride permitting and inspection chapter.[28] Diligence should review permits, inspection records, incident history, insurance coverage, waivers, and compliance procedures at the site level.

8. Competitive dynamics and consolidation

The starting point is extreme fragmentation — a CR50 of just 18% means the 50 largest firms control less than a fifth of revenue.[2] Competition is overwhelmingly local: a venue competes with the other ways families and tourists spend a Saturday within driving distance, not with a national rival.

The most defensible platforms tend to combine strong locations and real-estate access, repeat-use memberships, recognizable brands, reliable safety and service standards, group-sales capability, and centralized booking, pricing, marketing, and purchasing scale. Two consolidation forces are reshaping the top of the market, and both largely bypass public shareholders:

1. Franchising. Brands like Urban Air and Sky Zone scale by selling franchises, spreading a recognizable format and shared marketing across hundreds of independently owned units — building brand equity and buying power without the franchisor funding every build-out.[17][19]
2. Private-equity roll-ups. The defining trend of 2024-2025 has been institutional capital pouring into youth sports (Unrivaled Sports, IMG Academy, plus facility and tournament operators) alongside continued family-entertainment consolidation (Seidler Equity's Unleashed Brands; Palladium's Sky Zone; Five Star). The thesis is to professionalize thousands of "mom-and-pop" operators and re-rate the combined platform.[18][19][20][23]

Consolidation is not automatically value-creating. Roll-ups may combine venues with different customer bases, lease profiles, and safety standards — and a family-entertainment-center acquisition can add bowling, arcade, or amusement-park revenue that does not belong in 713990. The recurring competitive risks inside this pattern are novelty fade and overbuilding: successful formats (trampoline parks, escape rooms, axe throwing) attract copycats until local markets saturate, triggering price wars and margin compression.[17][11]

9. Risks

• Cyclicality. Discretionary, deferrable spending that contracts fast in recessions and when household budgets tighten.[10]
• Fixed-cost fragility. High operating leverage cuts both ways — a soft season or a demand shock (a pandemic-style shutdown) can wipe out a year for a venue that still owes rent and debt.
• Injury liability and insurance. Physical-activity businesses face lawsuits, rising premiums, sometimes limited coverage availability, and reputational damage from accidents; some kid-focused franchisors have faced litigation.[19][25]
• Overbuilding and novelty fade. Trend-driven formats can saturate a local market and lose their pull, stranding capital in overbuilt attractions.[11]
• Weather and climate. Outdoor operators are exposed to bad seasons, drought (rafting), and heat/wildfire disruption; seasonality concentrates the year into a few peak periods.
• Labor. Low-wage, seasonal, high-turnover staffing (~$27,000 average pay) is sensitive to minimum-wage changes and tight labor markets.[3]
• Real estate. High rents, lease renewals, and poor site selection can sink otherwise sound formats; attraction obsolescence demands recurring maintenance capital.
• Franchise/PE-specific risks. Franchisee conflicts and quality control for franchisors; leverage and exit-timing risk for the debt-funded roll-ups.
• Regulatory patchwork. Inconsistent state safety regimes create compliance complexity and headline risk after any high-profile accident.[25]
• Disclosure and data. Limited public-company disclosure and thin trading liquidity in the few listed names, plus federal data that undercount small, nonprofit, government, and nonemployer activity.[5][6]

10. How to invest and the outlook

Public-market routes (limited). There is no clean listed pure play. The practical choices are:

1. Direct operating exposure through Golf Entertainment Group (GLFE), accepting small-company and thin-liquidity risk.[14]
2. Minority/indirect exposure to Topgolf through Callaway (CALY), recognizing CALY is primarily a golf-equipment company after the 2026 transaction that moved ~60% of Topgolf to LGP.[12][13]
3. Experiential real estate through EPR Properties (EPR), where the analytical drivers are rent coverage, lease terms, tenant quality, and interest rates rather than venue operations.[15]
4. Adjacent listed leisure names (Six Flags/Cedar Fair, Dave & Buster's, Bowlero) — only after confirming which revenue actually falls within 713990; broad consumer-discretionary or leisure ETFs touch the theme only diffusely.

Net: the public market is a poor instrument for owning this specific industry today.

Private routes (where the action is). For accredited and institutional investors, the live opportunities are private: buying or franchising a venue, backing a franchising platform, or investing alongside the private-equity firms rolling up youth sports and family entertainment. This is capital-intensive and operationally hands-on; the underwriting focus should be site-level cash flow, repeat visits, membership retention, safety record, lease duration, maintenance needs, and realistic new-unit payback.

Near-term drivers to watch (forward-looking). The youth-sports investment wave — whether the roll-ups can deliver the promised professionalization and exit multiples — is the biggest swing factor and could eventually produce a larger listed operator. Trampoline/adventure-park growth is expected to continue but faces saturation in dense markets. Consumer-discretionary strength, weather, and the durability of the experience-economy shift will set the cyclical backdrop. And the completed Topgolf take-private (effective January 2026) removed the sector's most visible public plank — a reminder that, for now, this is an industry to understand mostly from the private side.[12][23][10]

The right investment thesis is therefore not a single industry multiple or a market-wide "recreation" growth rate. It is the identification of durable local demand, repeatable unit economics, and an ownership structure capable of scaling without compromising safety or customer experience — and returns will depend more on subcategory, location, operator quality, and lease economics than on the sector's headline growth.
