Our World in Data is an online publication that shows how living conditions are changing. The aim is to give a global overview and to show changes over the very long run, so that we can see where we are coming from and where we are today. We need to understand why living conditions improved so that we can seek more of what works.

We cover 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. For each topic the quality of the data is discussed and, by pointing the visitor to the sources, this website is also a database of databases. Covering all of these aspects in one resource makes it possible to understand how the observed long-run trends are interlinked.

The project is produced by the Oxford Martin Programme on Global Development at the University of Oxford, and is made available in its entirety as a public good. Visualizations are licensed under CC BY-SA and may be freely adapted for any purpose. Data is available for download in CSV format. Code we write is open-sourced under the MIT license and can be found on GitHub. Feel free to make use of anything you find here!
