What it covers
The first release covers five annual GDP measures for the 19 sovereign G20 countries. More subjects wait for an accepted source, reuse decision, and comparison rule.
An economic scoreboard with the source left on.
Purpose
TrackPodium makes a small set of comparable economic series easy to inspect before sending developers to the underlying Narwhal data work.
Ownership
TrackPodium and Narwhal API share a publisher. The relationship is stated on ranking pages and in the footer because TrackPodium is a marketing surface for Narwhal.
What it avoids
There is no permanent "best country" claim, composite score, anonymous expert verdict, paid position, or ranking made from mixed periods.
Corrections
Source revisions belong in a new versioned export. Editorial corrections change the canonical page without creating a duplicate annual article.
