Omitting the note misrepresents the assessment. ## Who it is for Journalists covering global development, public health, climate, energy, poverty, education, or population trends. Reporters who need contextualized long-term data with ready-made visualizations for stories. Data journalists who want clean, well-documented global datasets. Fact-checkers verifying claims about global trends. Educators and students studying global change. Anyone writing about how the world is changing and needing reliable data to support the narrative. ## Editorial take Our World in Data is the best single source for contextualized global data. Founded by Max Roser at the University of Oxford in 2011, it is a research project of the Global Change Data Lab and the Oxford Martin Programme on Global Development. A team of nearly 30 researchers, developers, and data specialists compiles data from official sources (World Bank, WHO, UN, national statistical offices, peer-reviewed research) and publishes it in standardized, interactive formats with explanatory articles. The key differentiator is not just the data but the research context. Each topic page explains methodology, limitations, and how to interpret trends — something raw data portals never provide. The interactive charts are embeddable with a single click, CC-BY licensed, and automatically cite their sources. For journalists, this means you can go from 'I need a chart of global life expectancy trends' to an embeddable, properly sourced visualization in under a minute. The entire codebase is open source on GitHub, including the data pipeline (ETL), the charting library (Grapher), and all article content. Data is downloadable in CSV format from every chart. Coverage is strongest on global development topics: poverty, health, education, energy, environment, food, population, technology, and conflict. It is weaker on country-specific politics, economics below the national level, or topics not covered by international statistical agencies. The platform's long-term perspective — showing trends over decades or centuries — is particularly useful for countering presentism in news coverage. ## Best for / not for **Best for:** Embeddable charts and visualizations for global trend stories. Long-term data on health, poverty, energy, climate, education, and population. Cross-country comparisons on development indicators. Contextualizing breaking news with historical trends. Downloading clean, well-documented global datasets. Understanding methodology and limitations of global statistics. **Not for:** US-specific or subnational data (use Census, BLS, Data.gov). Real-time or breaking news data. Country-specific political or economic analysis below the national level. Proprietary or paywalled datasets. Topics not covered by international statistical agencies.
