8. How we select and verify statistics
Each statistic must come from a primary source (a platform, regulator, research firm or large-scale study), name its year, and still be the latest edition when reviewed. We drop figures when their source publishes a newer edition and we cannot confirm the update. Ranges are shown when reputable studies disagree. If you spot a figure that has been superseded, let us know through the contact page and we will update it in the next review.
