Frequently asked questions and legal information

A country is not the same as a sovereign state. What is considered a country on WorldData.info and how it was decided in individual cases can be found here: What is a country?

Our database contains several million individual data items. Key data such as economic data or population figures for countries are updated several times a year. Population figures for cities with less than one million inhabitants are updated every several years. The rest of the data is updated about once a year. If a country has not yet published data for the last or penultimate year, we present the latest official data. Unless explicitly stated otherwise, we do not produce our own projections or estimates.

Not all, but at least some data can be downloaded as a CSV file.

Individual data are not protectable and may of course be copied, used or distributed. Data collections (e.g. IQ by country or Average body height) compiled through time-consuming research, evaluations, filtering and weighting of multiple sources and are indeed subject to copyright.
If you need this data for school or university, but do not earn money and do not reproduce or publish it otherwise, you are welcome to use them. In all other cases, where a not inconsiderable part of a data collection is copied, please just ask.

However, the content requirements are high. Your guest article must be available in all 5 languages. We will mark included links as "sponsored" or "nofollow" as long as they do not lead to authoritative sources.
