Public brief / source-backed packet

Health care and social assistance: Median HHI briefing

Orient readers to observed changes, evidence custody, and the questions that still require investigation. This packet keeps 1 latest-to-prior observation across 1 evidence system separate and does not rank or combine them.

Census industries / Median HHI

Health care and social assistance

0
201735.8
5 years
202235.8

The 2022 median is unchanged than the 2017 median across the same published strict-match screen. Sector medians are orientation statistics, not sector HHI values or legal market findings.

Research questionWhich six-digit industries drive the sector shift, and where do product, geography, entry, conduct, price, quality, or enforcement records justify deeper market-level research?
Interpretation boundary

Every signal compares declared observed anchors inside the same series or cross-section. Missing years are not interpolated, intervals are not annualized, and market, industry, geographic, business-flow, and merger measures keep separate units, universes, period bases, and legal meanings. Antitrust Radar does not combine them into a composite competition score.

Publication standard

A briefing is a research handoff, not a finding of liability.

Every exported packet carries the observed comparison, source register, bounded interpretation, next research question, and the global no-composite-score rule.

  1. 01
    State what changed

    Report the exact prior and latest anchors with their period basis and interval.

  2. 02
    Keep systems separate

    Do not compare the magnitude of unlike HHI, share, business-flow, transaction, and review-rate changes.

  3. 03
    Open the investigation

    Route each signal into its underlying profile, explorer, source records, and research question.
