How we work
Countries in Data is built on one rule: a number is published only together with the organisation that produced it, the dataset, the date and a link. Below is how we apply the rule.
Official sources only
We use Eurostat, the World Bank, Statistics Poland (GUS), the US Census Bureau and NASA. Secondary retellings, press releases without a dataset and anonymous estimates are not accepted.
A source next to every number
The source and the date are shown beside the number, not at the end of the page. A tap or a click opens a card with the organisation, the dataset, the reference date, the access date and the link.
Comparisons are data, not verdicts
We put countries on one scale and describe what the numbers show. We do not rank countries as better or worse and do not draw conclusions about causes that the data cannot support.
Dates and revisions
Statistical offices revise their figures. We show both the reference date of the data and the date we accessed it, and we mark provisional values.
How we check the numbers
Every number is copied from the dataset by an identifier, not retyped from an article.
A second editor compares the published number with the source on the day of publication.
Where two official sources exist, we compare them and note any difference.
Derived values, such as differences and shares, are calculated from the displayed numbers and are labelled as an editorial calculation.
What AI does
Artificial intelligence helps us prepare drafts of texts and tables. It does not choose sources, does not supply figures from memory and does not publish anything on its own. Each text carries a label, and an editor reads it against the sources before publication.
What we do not do
- We do not give advice on relocation, taxes, salaries or personal finance.
- We do not publish rankings of where life is better.
- We do not use numbers without a named source and a date.
- We do not load fonts, scripts or counters from third-party servers.
Corrections
If you find a number that differs from its source, write to the editorial team. We correct the text, mark the change with a date and keep the previous value in the page history.
