Wikidata
Structured data repository
Wikidata is a free, collaborative knowledge base operated by the Wikimedia Foundation that serves as a central repository for structured data used by Wikipedia and other Wikimedia projects.
It stores information in a format that computers can easily read and process, linking facts about people, places, concepts, and things across languages.
The article pulls its population statistics directly from Wikidata.
Anyone can edit and contribute to its growing database of interconnected information.
