Methodology

Last updated: 01.10.2026

This page explains where our information comes from, how it is checked, how it is presented and what its limits are. It applies to all country profiles, institution pages and announcement summaries on NexaNations.

1. Source hierarchy

We use sources in the following order of preference. A lower-level source is used only when no higher-level source is available.

  1. Primary official sources: official government portals, official gazettes, constitutions, parliaments, central banks and national statistical offices.
  2. International organizations: United Nations bodies, the International Monetary Fund, the World Bank, the United Nations Development Programme and similar institutions.
  3. Recognized reference datasets and indices: for example ISO 3166 and ISO 4217 standards, Wikidata and GeoNames identifiers, Transparency International, Reporters Without Borders and the Henley Passport Index, each clearly named.

We do not use anonymous, unattributed or crowd-sourced figures as a source of fact.

2. Which source is used for which data

  • Identity and codes (ISO codes, official name): ISO 3166, official government portals, Wikidata.
  • Government and leadership: official government and parliament websites.
  • UN membership: United Nations member states list.
  • Economic indicators (GDP, growth, inflation, unemployment): International Monetary Fund, World Economic Outlook.
  • Trade and social indicators (exports, imports, life expectancy, literacy, internet use): World Bank, World Development Indicators.
  • Human Development Index: United Nations Development Programme.
  • Corruption Perceptions Index: Transparency International.
  • Press freedom rank: Reporters Without Borders.
  • Passport rank: Henley Passport Index.
  • Tourism arrivals: UN Tourism.
  • Exchange rates: European Central Bank euro reference rates, and ExchangeRate-API for currencies the ECB does not publish.

3. Verification process

  1. Data is collected into a structured master file, keyed by ISO country code, before it reaches the website.
  2. Each value is checked against the source listed for its category. Values that cannot be traced to a source are left empty rather than estimated.
  3. Imported or AI-assisted content is created as a draft and is never published automatically.
  4. An editor reviews the profile and sets its data status.

Data status labels

  • Verified: the profile has been checked against its listed sources on the date shown.
  • Under review: the profile has been published or updated, but its full check is not yet complete. Use it with extra care.

4. How figures are presented

  • Numbered references such as [1] link each key fact to the source list at the end of the page.
  • Statistics show their reference year. Values for the current or a future year are labelled est., because they are estimates or projections.
  • Empty fields are hidden. We prefer showing nothing to showing a guess.
  • Where sources disagree, we use the source listed for that category and do not average or combine figures.

5. Neutrality and disputed topics

We do not take a position on territorial, sovereignty or political disputes. Country names follow widely used international conventions for consistency only. Where the status of a territory or a fact is contested, we say so plainly rather than choosing a side.

6. Official announcements and AI assistance

Announcements are collected only from official, publicly accessible sources. Summaries may be drafted with AI assistance, are reviewed by an editor before publication, are labelled as AI-assisted, and always link to the original document. The original source is authoritative; our summaries are not official translations.

7. Updates and review

Each country profile shows the date it was last updated. Profiles have a scheduled review date, and they are also reviewed whenever a reader reports a possible error. Confirmed changes are recorded on our corrections page.

8. Limitations

  • Official statistics are revised over time, and different organizations may publish different values for the same indicator.
  • Some indicators are published with a delay of one or more years.
  • Exchange rates are daily reference rates and do not reflect bank or retail rates.
  • Automatic translations offered on the site are machine-generated; the English version is authoritative.
