Our World in Data

Our World in Data is a British data visualization project based in the United Kingdom.

Our World in Data notes that it has four main sources of research it uses for publication: “specialized institutes” such as the Peace Research Institute Oslo, research articles, international institutions like the World Bank, and “official data from government sources.”1)


Our World in Data began as compiled research notes written by Global Change Data Lab founder Max Roser in 2011. Roser originally aimed to write a book on international issues before deciding to create a website.2)

Roser created the first version of Our World in Data in 2013 and applied for a research grant from the London-based Nuffield Foundation, which initially rejected the application but accepted a renewed application in 2014 and provided OWID with a grant of £75,883 (approximately $90,318).

In 2018, OWID successfully applied to startup incubator Y Combinator, becoming part of the YC Winter 2019 batch of startups.3)


The organization began the COVID-19 pandemic with six staff members, and grew to 20 by late 2021.4) 5)


OWID is a project of the Global Change Data Lab (GCDL) and is hosted at the University of Oxford.6)
