Source refresh · 8 October 2026: UCDP historical and January–August candidate downloads, World Bank population and OWID life expectancy were re-fetched and byte-identical. The World Bank crude birth-rate response was updated. V-Dem v16 remains the latest listed release. Other layers retain their existing dated snapshots and were not relabelled as live. Read the refresh audit and hashes.
The dedicated Gas and Civilian Casualties source guide records the new maps' publisher links, observation dates, geographic resolution, units, currency conversion, external Gaza context, and exclusions.

BRICS source availability: The roster used in this build was retrieved from BRICS Brazil on September 21, 2026. The original address, https://brics.br/en/about-the-brics, failed DNS resolution when checked on September 23. Membership observations and their original attribution are unchanged. The Library of Congress BRICS background and source guide provides an accessible route to institutional references; it is a source guide, not a replacement dataset.
The organization layer uses the UN member-state roster, NATO member countries, the BRICS roster provenance and source guide, the EU member roster, and the ASEAN member roster. The World Economic Forum membership source describes company and stakeholder communities; it is kept as non-state organization metadata and is not inferred as state membership.
