Most global corruption statistics are based on estimation, extrapolation, or generalisation. How plausible are they? We review ten of the most widely cited claims, tracing each to its source and evaluating its credibility and reliability. We found that none could be classified as credible, and only two came close. After critiquing these oft-cited figures, we suggest five ways that organisations can improve the statistical claims about corruption that they present to the public.
