Data infrastructure / open access
Download the records behind the research, including market shares, concentration measures, official events, and source references. Coverage and missing values are documented for each dataset.
Source records move through market definitions, concentration calculations, confidence labels, and public data endpoints — 45 source records, 12 market profiles, 235809 record rows plus a 1 row summary endpoint across 62 API endpoints.

Visualization recipes
Each recipe keeps the same contract: open endpoint, declared encoding, visible caveat trail, and a route into analysis or public action.
Endpoint to evidence route
Rows become visual claims only when the route is inspectable.

Visible limit
Pairing is exact and descriptive; missing sides are not imputed and association is not causation.
Question
How do two bounded measures relate inside the same entity-period universe?
Caveat
Pairing is exact and descriptive; missing sides are not imputed and association is not causation.
Encoding: Matched x/y planes with visible means, Pearson r, and atomic observation IDs
Inspect association, select a point, and return to both source-custodied measures.
Question
Where is concentration geographically visible enough for local review?
Caveat
State rows do not replace local market definition.
Encoding: State-level HHI, classified by concentration class
Find places where market power needs local review.
Question
Which firms occupy most of the visible market share?
Caveat
Private or aggregate rows can understate firm-level rivalry.
Encoding: Firm share percentage sized by tile area
Show whether a market is dominated or contested.
Question
Is concentration persistent or only a one-year spike?
Caveat
Dashed anchor connections are not interpolated annual estimates.
Encoding: Released HHI anchors with definition and source custody
Inspect persistent concentration without filling missing years.
Question
Which claims depend on the same public sources?
Caveat
Citation coverage does not prove the causal claim.
Encoding: Sources connected to markets and reports
Keep every public claim tied back to evidence.
The API is a starting point, not a legal conclusion. Pair downloads with methodology notes, source records, and the data-gaps report when citing market concentration.
