Method

The site displays supplied Next RAI scores and nine service dimensions without recalculating them. Only complete results are ranked.

Data sources

• Country results workbook transferred from the alternate project folder on 2026-10-23; includes supplementary country scores.
• Natural Earth v5.1.2 — country boundaries (public domain)

Limitations

• Only complete results are ranked. Missing scores remain unavailable; partial scores are excluded from rankings, averages and map colors.
• Marshall Islands: the source requires methodological review for island or archipelago geography. Interpret its score with this limitation.
• Official World Bank values, where available, refer to country-specific years. Classic RAI proxy is a separate project estimate, not official World Bank data.
• Ranks use descending scores and shared ranks for ties. Categories: High ≥70, Moderate 50–<70, Low <50. The four map color bands remain unchanged.
• CYP uses the requested display name Turkish Republic of Northern Cyprus (TRNC). This is a display alias only; the workbook identifier, score and original map geometry have not been reassigned.
• Regions retain source groupings. SDS maps to SSD; KOS is a non-ISO source identifier. Import date is not the observation year. The calculator weights are illustrative.
• Supplementary records have all nine dimension scores but lack source publication status, region and rural population metadata. They are included as supplied scores; missing metadata are not estimated. The workbook Notes sheet predates these additions.

Map boundaries

Natural Earth v5.1.2, 1:50 million scale. Public domain. Country boundaries are generalized and do not imply a position on sovereignty.
