Our World in Data

• Find chartsSearch Our World in Data's charts and get back the name of each one, which is what every other step here is keyed on. Search by subject - 'life expectancy', 'solar power', 'child mortality' - and narrow to a topic or to the countries you need, so a chart that does not cover your country is ruled out before a workflow is built on it. This is the step to start with: it turns a question into the chart that answers it. No account or API key required.
• Find indicatorsDescribe what you are looking for in plain English and get back the indicators that mean it, ranked by how closely. This searches by meaning rather than by keyword, so 'how many people die from dirty air' finds the air pollution death rates without using any of those words, and it reaches every indicator Our World in Data holds rather than only the ones a chart is drawn from. Pair it with 'Get indicator data' to read the numbers. No account or API key required.
• Find articlesSearch what Our World in Data writes rather than what it charts: research articles, the short daily data insights, and the topic pages that explain a subject end to end. Each result comes back with its title, its authors, when it was published and an excerpt. Leave the search text blank and it returns the most recent pieces, which is how a workflow that posts 'what's new from Our World in Data' to a channel is built. No account or API key required.
• Get chart detailsEverything about one chart except the numbers: what it measures and in what unit, what Our World in Data says you should know about it, which countries and years it covers, when it was last updated and when it is due to be updated next, and the line that credits its sources. Read this before building on a chart, so a workflow is written against what it actually holds, and read it alongside the numbers so a report cites them properly. No account or API key required.
• Get a country's latest valueOne country's most recent figure from one chart, with the year it is from, the unit it is in and the line that credits its sources - plus where the number started and how far it has moved since, so a sentence can say both. This is the step for putting a real number into an email, a message or a document. Leave the date blank and it stays current on its own as the statistical agencies publish. No account or API key required.
• Get a country's data over timeOne or more countries' numbers from one chart across a span of time, as a row per country per year - and, alongside them, a summary of each country saying where it started, where it ended, how far it moved in the unit and in percent, and its highest, lowest and average. That summary is usually the answer: it is what turns a table of numbers into a sentence a report can use. Leave the dates blank for everything the chart holds. No account or API key required.
• Compare countriesPut several countries side by side on one chart, ranked largest first, each with its share of their combined total and how far it is behind the leader. Every country is read at its own most recent year, because statistical agencies publish on their own schedules and insisting on one shared year would silently drop whoever had not reported yet. Anything the chart does not cover is reported as missing rather than quietly left out. No account or API key required.
• Rank countriesThe highest or lowest countries in the world on one chart, with the global figure alongside when the chart publishes one. Continents, income groups and the world itself are left out by default - they are much larger than any country, so a ranking that kept them would be a ranking of continents - but they can be put back in. Each country is read at its own most recent year. No account or API key required.
• Get indicator dataRead the numbers behind one indicator from 'Find indicators', whether or not any chart is drawn from it - which is most of them. The values arrive keyed by internal entity number; this step turns them back into country names, narrows them to the countries and years you asked for, and returns the indicator's unit, its dataset and the organisations that collected it. No account or API key required.
• Get a chart imageA picture of a chart as a link you can drop straight into an email, a Slack message or a document - drawn for the countries and years you choose, as the chart or as the world map, at the size the place it is going needs. The link is checked before it comes back, so a step never hands on an address that will show a broken image. Our World in Data's charts are CC BY, so the credit line to put beside it comes back too. No account or API key required.
