Data register
This page is the public data inventory. It is intentionally more specific than a footer credit. If a licence, reference year or coverage count is missing, that is a bug, not a detail.

Update cadence
Known limitations
Issuer holdings pages
iShares, Vanguard, Amundi and Xtrackers public pages are not a commercial redistribution licence. No scraping is used.
IMF WEO
GDP series are useful, but IMF bulk/automated access and commercial reuse terms need explicit review. World Bank is the selected default.
WFE raw statistics
WFE's own statistics portal restricts reproduction absent permission. The World Bank-published indicator is used under its stated CC BY 4.0 metadata.
