Public anchor horizon

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.

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.
