Each hub collects the reports for one industry, with an overview of the key figures and links to every report in it.
How we work
We take each number from the organisation that produced it: statistical offices, central banks, international bodies, regulators, original surveys and company filings.
Before a report goes live, every figure is compared with its source and units, dates and definitions are checked. Numbers we cannot confirm are left out.
Every chart carries a source line, and every report ends with a list of its sources, so any number can be traced back and judged by how recent it is.
Forecasts and estimates are marked as such with the name of who made them. When a source revises its data we update the report, and corrections are noted openly.
Read our full methodology and editorial policy. Found a number that looks wrong or out of date? Tell us and we will check it against the source (corrections policy).
Editorial team
Every report is researched and written by a named member of our team, who is shown on the report.

Managing Editor
Heads the Business Stats editorial team, sets our sourcing and verification standards and gives final approval on every report before it is published.

Content Editor
Writes and edits the explanatory notes that accompany each chart, so readers understand what a figure measures and what it means.
About Business Stats
Business Stats publishes statistics reports on companies, markets, economies and consumers. A report brings together the figures on one question, such as how fast the world economy is growing, which companies earn the most or how many people use a platform, and explains what the numbers measure and how they have changed over time.
The figures come from the organisations that produce them: national statistical offices, central banks, the World Bank, IMF and OECD, regulators, industry bodies, original surveys and company annual reports. Each report lists those sources at the end, shows the date of every figure and labels forecasts as forecasts.
Our readers are students and researchers, journalists, analysts and marketers who need a reliable number and a source to quote. You can start from an industry hub such as economy and politics, technology and telecom, finance and insurance, media and streaming or energy and environment, or search for a company, market or country. Every chart can be downloaded with its source line, and every report can be read free of charge.
