Where bounded market histories exist

x = release year
line = same measure
Public concentration anchors by market and yearFifty-nine source-backed HHI, CR4, and leading-participant share anchors across eight observed market definitions. Horizontal position represents release year, color identifies the bounded measure, hollow points retain definition restrictions, dashed paths join released anchors for the same measure without estimating intervening years, and every point opens its exact market series.Beef meatpacking1980-2019Beef meatpacking;

Anchors, not estimatesEvery point is a released observation. Dashed paths expose evidence continuity without filling or carrying values across missing years.
Definitions before comparisonThe horizon locates evidence in time; it does not rank unlike products, geographies, denominators, or measure families on one value scale.

Select a market with published CR4 anchors or open the table to inspect definition-blocked evidence.

Dashed segments connect public anchors for legibility; they do not estimate missing years. Event lines provide timing context only and do not identify causal effects.

Measurement basis

USDA-reported share of steer and heifer purchases handled by the four largest beef packers

Cross-market posture

not comparable

A national aggregate buyer-side CR4 is not an HHI, does not identify individual firms, and does not define the regional procurement choices facing a particular rancher or feeder.

Anchor rule

No annual values are filled, carried forward, or interpolated. Index and change modes re-express only the published anchors inside the chosen window.

Definition rule

Product boundaries, geographies, denominators, and metric families remain distinct. Screens are not merged into a synthetic economy-wide finding.
