Column height and colour show people per km² by unit, in quantile fifths among the units shown (the key on the map gives the breaks); units with no people on the grid are grey, not the lowest class; the raster beneath is the GHSL 2025 population grid. Source observations, not index values. Choose a humanitarian figure from the list to colour and raise the units by it; each figure shows its source on the unit page. Select a unit to drill into the units inside it; the path above the map climbs back.

Isimo

The methodology, structure and definitions of The Global Risks Index are a preparatory working draft (2026), circulated for review and comment and not for implementation. No value appears until an edition is released from a governed evidence cut; values then carry intervals, classes, sources and their correction pathway. Simulators run the published methods on numbers you choose and never show a NXS-GRX value.

A country profile reads public evidence about a place. It is not a statement by or about the policy of any government, takes no position on the status of any territory, and does not imply a national programme or participation. Names follow UN M49.

Lokho i-NXS-GRX engeyikho

I-NXS-GRX iwulwazi locwaningo nokuhlaziywa kobungozi. Akusona isilinganiso sesikweletu noma se-ESG futhi ayisebenzisi sikali sokulinganisa, akusona isilinganiso samathuluzi ezimali, akuzona izibalo ezisemthethweni, akusona isixwayiso esiphuthumayo noma ukuhlukaniswa okusemthethweni, futhi akusona iseluleko. Akumele isetshenziselwe ukuhlola abantu ngabanye. Izigaba zobungozi ziyimigoqo esikalini esishicilelwe, akukaze kube ukulandelana kwamazwe noma kwabantu.

Amasiginali e-Pulse namathuba okubikezela ayimininingwane yokubuyekezwa ngabaphathi abanegunya, akukaze kube izixwayiso zomphakathi; izixwayiso ezisemthethweni zivela kuphela kubaphathi abanegunya.

The Nexus Consortium is stewarded by three independent not-for-profit institutions: The Global Centre for Risk and Innovation (GCRI), through GCRI US in Washington, DC and GCRI Canada in Ontario, with GCRI Canada as Lead Institution, Consortium Secretariat and lead contracting organisation; The Global Risks Forum (GRF); and The Global Risks Alliance (GRA). Technology, infrastructure and service providers work with the Consortium at arm’s length under written agreements, like every other external party in the public-private-planet model, and hold no role in its stewardship.

Avis en français

La méthodologie et les définitions du NXS-GRX sont un projet de travail préparatoire (2026). Le NXS-GRX est une information de recherche et d’analyse des risques : ni notation, ni indice de référence financier, ni statistique officielle, ni alerte, ni conseil. Les classes de risque sont des bandes sur une échelle publiée, non des classements.
