U.S. economic observatory / evidence by year
U.S. Competition Yearbook
Explore the evidence available for a selected year from 1978 to 2026. Data gaps remain visible, and releases from different periods are not treated as a synchronized panel.

The Yearbook is an evidence calendar, not a synchronized national panel. Every row keeps its own unit, universe, period basis, source, and legal meaning. Missing years remain explicit gaps; values are never forward-filled, normalized onto one scale, added together, or converted into a composite competition score.
Yearbook method
A chronology of evidence, not a chronology of one economy-wide score.
The calendar is useful precisely because its lanes do not line up automatically. It shows where observation density is strong, where the current release is silent, and which public route can answer the next bounded question.
- 01Select the year
Start with what is encoded for the period rather than assuming every system publishes annually.
- 02Read within the lane
Interpret values only against the metric, entity, unit, universe, and period contract shown on the row.
- 03Open the source route
Use the exact profile, source dossier, or public endpoint before drawing a research or policy conclusion.

The Yearbook packet is convenient for one selected year. These routes remain the authoritative complete downloads for each underlying evidence system.
