Our World in Data

Our World in Data (OWID) is a scientific online publication that focuses on large global problems such as poverty, disease, hunger, climate change, war, existential risks, and inequality.
It is a project of the Global Change Data Lab, a registered charity in England and Wales, and was founded by Max Roser, a social historian and development economist. The research team is based at the University of Oxford. The organisation is chaired by Hetan Shah.

Our World in Data uses interactive charts and maps to illustrate research findings, often taking a long-term view to show how global living conditions have changed over time.
History
Roser began his work on the project in 2011, adding a research team at the University of Oxford later on. In the first years, Roser developed the publication together with inequality researcher Sir Tony Atkinson. Hannah Ritchie joined in 2017 and became Head of Research. Edouard Mathieu joined in 2020 and became Head of Data. The organization began the COVID-19 pandemic with six staff members, and grew to 20 by late 2021.
In 2019, Our World in Data won the Lovie Award, a European web award, and was one of three nonprofit organizations in Y Combinator's Winter 2019 cohort.
Beginning in 2020, Our World in Data added an emphasis on publishing global data and research on the COVID-19 pandemic:
They created and maintained a worldwide database on vaccinations for COVID-19, which was used as the source for data published by the World Health Organization, researchers and other international organizations, journals, and numerous newspapers.
Similarly, the team built and maintained a global dataset on COVID-19 testing which was used by the United Nations, the White House, the World Health Organization, and epidemiologists and researchers, and also published data such as hospitalizations and computations of excess deaths.
In 2021 the team began campaigning for the International Energy Agency to make the data it collects from national governments publicly available.
Funding and collaborations
Global Change Data Lab, the non-profit that publishes Our World in Data and the open-access data tools that make the online publication possible, is funded through a mix of grants, sponsors, and reader donations.
The first grant to support the research project was given by the Nuffield Foundation, a London-based foundation focused on social policy.
Other grantors supporting the project have included the Quadrature Climate Foundation, the Bill and Melinda Gates Foundation, and a grant from German philanthropist Susanne Klatten. In the past, Our World in Data has also received grants from the World Health Organization, the Department of Health and Social Care in the United Kingdom, and the Effective Altruism Meta Fund.
Reader donations are also a major source of funding. In 2020, more than 3,000 individuals supported the project, exceeding 4,000 donors by 2023. The list of donors includes Jamie Metzl and YouTuber Hank Green.
The research team collaborated with the science YouTube channel Kurzgesagt.
In the coronavirus pandemic, the team partnered with epidemiologists from Harvard's Chan School of Public Health and the Robert Koch Institute to study countries that have responded successfully in the early phase of the pandemic. Janine Aron and John Muellbauer worked with OWID to research excess mortality during the pandemic.
In 2022, FTX's Future Fund offered Our World in Data a $7.5 million grant to support their activities. Max Roser told Fortune that Our World in Data's board of trustees ultimately rejected the grant money after conducting due diligence and other checks.
