Territorial Observatory
Data methodology
Our doctrine fits in one sentence: no data without a cited source and a displayed vintage.
What this page is for
It accounts for how the Observatory's figures are produced: where they come from, what they cover, what they do not say and how they are updated. It is the counterpart of our rule: no data without source and date.
- Sources: the World Bank public API, extraction date displayed.
- Scope: six CEMAC countries at national scale, pending official sub-national sources.
- Acknowledged limitations and a published, traced correction procedure.
Sources, scope, limitations and updates
The four questions a reader must be able to ask of any figure published here, and our answers.
Sources
The indicators published in this version of the Observatory come from World Bank — World Development Indicators (WDI), queried through the official public API (api.worldbank.org). Extraction date: 2026-07-22. Every value displays its vintage (the year of the data point, which may differ from the extraction year): we publish the latest available value per country.
Scope
Current coverage: the six CEMAC countries (Cameroon, Gabon, Congo, Chad, Central African Republic, Equatorial Guinea), at national level. Sub-national breakdowns (regions, municipalities) will be introduced with dedicated official sources (national statistics institutes, sector data) under the same citation requirement.
Acknowledged limitations
Some series have breaks or missing years; some countries lack a recent value for every indicator — in that case the value is not displayed rather than estimated. Cross-country comparisons must account for the vintages displayed.
Updates
Data is regenerated from the API at each site update; the extraction date is displayed above. Report any error to hello@xp-nova.com — corrections are published and tracked.
