Our World in Data


Our World in Data is a scientific online publication that focuses on large global problems such as poverty, disease, hunger, climate change, war, existential risks, and inequality.
The publication's founder is the social historian and development economist Max Roser. The research team is based at the University of Oxford.

Mission and content

The mission of Our World in Data is to present "research and data to make progress against the world’s largest problems".
The web publication on global development uses interactive data visualizations to present the research findings on development that explain the causes and consequences of the observed changes. The aim is to show how the world is changing and why.
Our World in Data covers a wide range of topics across many academic disciplines: Trends in health, food provision, the growth and distribution of incomes, violence, rights, wars, culture, energy use, education, and environmental changes are empirically analyzed and visualized in this web publication.
It often takes a long-term view to show how global living conditions have changed over the last centuries.
Covering all of these aspects in one resource makes it possible to understand how the observed long-run trends are interlinked. The research on global development is presented to the audience of interested readers, journalists, academics, and policy people. The articles cross-reference each other to make it possible for the reader to learn about the drivers of the observed long-run trends. For each topic the quality of the data is discussed and, by pointing the visitor to the sources, this website works as a database of databases – a meta-database.
Our World in Data published a sister project called that presents all available data on the 232 SDG-Indicators with which the 17 Sustainable Development Goals are assessed.
In 2020, Our World in Data became one of the leading organizations publishing global data and research on the Coronavirus pandemic.
The team created and maintained the worldwide database on testing for COVID-19 which was used by the United Nations, the White House, the World Health Organization and epidemiologists and researchers.

History

Roser started to work on Our World in Data in 2011. During the first years he financed his project as a bicycle tour guide around Europe. Only later did he establish a research team at the University of Oxford that is studying global development.
In the first years Roser developed the publication together with inequality researcher Sir Tony Atkinson. The first grant to support the research project was given by the Nuffield Foundation, a London-based foundation focused on social policy. When the project ran out of funding it was rescued by the "Save OurWorldInData.org“ crowdsourcing campaign.
Until 2015 the project was built in "nights and weekends" by Roser. Only later was it developed into a research project at the University of Oxford.
In 2014 the site was read by 120,000 readers. Since then the number of readers increased. Between December 2018 and 2019 the site was read by more than 25 million readers. Our World in Data is most widely used in the anglophone world.
In early 2019, Our World in Data was one of only 3 nonprofit organizations in Y Combinator's Winter 2019 cohort.
In 2019 Tyler Cowen and Patrick Collison called for a new academic discipline of 'Progress Studies' that institutionalizes the mission of Our World in Data and Collison published a permanent recommendation to join the team of Our World in Data.
In 2019 Our World in Data won the Lovie Award, the European web award, "in recognition of their outstanding use of data and the internet to supply the general public with understandable data-driven research – the kind necessary to invoke social, economic, and environmental change."

Publishing model

Our World in Data is one of the largest scientific open-access publications. It is made available as a public good:
The team developed the Our World in Data-Grapher, a combination of database and visualization tool. The database includes more than 70,000 variables.

Collaborations and partnerships

The Our World in Data team partnered with several organizations:
The publication has received grants from the Bill and Melinda Gates Foundation and the Nuffield Foundation as well as donations from hundreds of individuals.
The non-profit Global Change Data Lab publishes the website and the open-access data tools that make the online publication possible. The research team is based at the University of Oxford's Oxford Martin School. Director is the founder Max Roser.
The Our World in Data research team also publishes their research work in a number of widely accessed media outlets including the BBC, Vox, The New York Times, The Guardian, and The Washington Post. The research team has also collaborated with science YouTube channel Kurzgesagt to reach millions of viewers.
As a complement to GDP environmental economist Cameron Hepburn proposed a comprehensive measure of wealth – including environmental and natural aspects – on Our World in Data.
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. Oxford professors Janine Aron and John Muellbauer worked with OWID to research the excess mortality during the pandemic.
The team's head of research is Hannah Ritchie. Esteban Ortiz-Ospina is senior researcher and head of operations.

Usage

Our World in Data is cited in academic scientific journals like Science, Nature, and PNAS.
In medicine and global health journals like the British Medical Journal or The Lancet and in social science journals like the Quarterly Journal of Economics Our World in Data has been cited.
The website is used widely in the media. The BBC and publications like The Washington Post, The New York Times, and The Economist regularly rely on Our World in Data as a source.
Tina Rosenberg emphasized in The New York Times that Our World in Data presents a “big picture that’s an important counterpoint to the constant barrage of negative world news”. Steven Pinker placed Roser's Our World in Data on his list of his personal “cultural highlights” and explained in his article on 'the most interesting recent scientific news' why he considers Our World in Data so very important.
Private sector companies, like McKinsey Consulting, rely on Our World in Data publications to understand emerging markets and changes in poverty and prosperity.
