2022 Economic Census / NAICS 81

Other services (except public administration)

The four largest firms in Other services (except public administration) accounted for 4.6% of the industry's 2022 sales, value of shipments, or revenue, and its concentration (HHI 10) ranks 15 of 17 sectors in the Economic Census. What is HHI?

National employer-firm concentration for this sector, measured from sales, value of shipments, or revenue. Census categories are statistical groupings, not necessarily antitrust markets.

Interpretation

The typical published detailed-industry HHI moved +3.6 pts. This distribution statistic is separate from the official broad-sector HHI row.

Classification boundary: 0 changed and 2 new detailed rows remain outside strict deltas.

Sector rows summarize strict six-digit NAICS matches. Their medians are not sector HHI values, legal antitrust markets, liability findings, or causal estimates. Vintage medians and the median of row-level changes are distinct distribution statistics and need not reconcile. Publication coverage varies by metric, and revenue changes are nominal.

NAICS 81 is the exact broad-sector contract used by this chapter. This atlas joins only exact broad-sector NAICS contracts across three separate Census systems: monthly Business Formation Statistics, annual Business Dynamics Statistics, and Economic Census industry structure. The release clocks, populations, denominators, and measures remain distinct. Positions are descriptive context, not composite competition scores, causal estimates, legal antitrust markets, or evidence that applications, entry, concentration, and competitive effects are interchangeable.

Single-sector bridge boundary

NAICS 81 is the sole declared Census-sector context for both the Other services JOLTS group and the Other services CES supersector, but the Census and BLS classification contracts remain distinct. JOLTS industry rates describe national labor demand and worker-flow activity in broad BLS industry groups. They do not measure employer concentration, monopsony power, wages, bargaining power, job quality, local labor-market conditions, worker substitutability, a legal labor market, or the competitive cause of a change. The job openings rate uses employment plus openings as its denominator. Hires, quits, and layoffs and discharges use employment. Rates may be compared across published industry groups within the same measure, but different measures must not be added together or treated as a common flow balance. CES employment, hours, and earnings describe national payroll jobs and establishment averages in broad private-industry groups. They do not measure unique workers, vacancies, employer concentration, monopsony power, bargaining power, job quality, a local or occupational labor market, a legal antitrust market, or the competitive cause of a change. All-employee hourly earnings are current-dollar averages and are not adjusted for inflation. Changes can reflect shifts in industry and worker composition. Employment is reported in thousands of payroll jobs, so multiple jobholders may be counted more than once. Compare industries only within the same published measure; do not add or ratio the three measures into a common score. The two releases remain separate and are not combined into a labor-market, monopsony, competition, welfare, or causal score.

Exact broad-sector boundary

BEA line 88 and Census NAICS 81 share the declared broad-sector classification used by this profile. BEA value added measures an industry's contribution to GDP. It is not sales, gross output, profit, a markup, market share, concentration, a legal antitrust market, or evidence of competitive harm or causation. Current-dollar value-added shares reflect both prices and quantities. Real value added uses chained 2017 dollars and is suitable for growth comparisons, but chained-dollar industry components are not additive. Quarterly levels are seasonally adjusted at annual rates, and quarterly growth and contribution measures retain BEA's published annualized convention. The BEA table contains nested industries, cross-industry aggregates, and addenda. Only the 20 major-industry rows form the composition view; summing those rows with their children, parent aggregates, or addenda would double count activity.

Exact accounting line

Census NAICS 81 and BEA summary industry 81 share the exact published code used by this profile. A domestic total-requirements coefficient reports the U.S. output required from the supplier-row industry, directly and indirectly, per dollar of output delivered to final use by the buyer-column industry. It is not observed spending, a contract, a firm supplier link, market share, concentration, a legal antitrust market, competitive harm, or causation. Rows are supplying industries and columns are buyer industries delivering output to final use. Reading down a buyer column traces upstream requirements; reading across a supplier row traces the industries whose final-use output requires that supplier. BEA requirements tables use fixed input structures, constant returns to scale, and no input substitution. Coefficients are average, ex-post industry relationships; domestic import adjustments are estimated and do not identify firm-specific sourcing. Diagonal values include an industry's own direct and indirect requirements. Published negative coefficients are retained as accounting adjustments and must not be ranked as positive supply requirements.

Bubble size describes economic weight inside this NAICS sector. HHI and CR4 remain national statistical screens, not product-market definitions or findings of market power.

Explicit research gap

No descendant market dossier is curated yet

The sector remains fully available as a Census structure screen. Product boundaries, geographic scope, and market-specific public sources still need to be assembled before a legal-market bridge can be published.

Descendant NAICS codes provide a research crosswalk only. They do not make a curated product and geographic market equivalent to its Census industry, and market metrics are never aggregated into a sector score.

Federal merger-review composition

Where NAICS 81 appears in HSR review releases

Each release aggregates its own published acquired-entity 3-digit rows. Volume, review stages, labels, denominators, and source custody remain separate from the Census concentration screen.

Interpretation boundary

This bridge joins only the exact broad-sector NAICS code published by both sources. The 2022 Economic Census sector row measures economy-wide employer-firm structure, while each HSR sector aggregate sums the release's published acquired-entity 3-digit rows. The shared code does not define a legal antitrust market, measure a sector merger rate, establish competitive harm, or score agency performance.

Intra-industry field

An intra-industry transaction means the acquiring and acquired persons both reported revenue in the same 3-digit NAICS code. It does not establish a horizontal overlap, relevant antitrust market, or competitive effect.

Industry screen, not market conclusion

A NAICS industry is a statistical classification, not a legally defined antitrust market. Use these national revenue concentration measures to screen where deeper product and geographic market analysis may be warranted, not to infer market power or liability.
