Research

Migration Watch approaches our research output carefully and diligently; while we have a proven track record of getting it right on the issue, we know how sensitive the topic is and ensure we provide neutral, non-partisan and numbers-based analysis. On that basis, we source our numbers from officially published statistics reports, most usually the Office for National Statistics (ONS), the National Audit Office (NAO), the Home Office (HO), and other arms of His Majesty’s Government. 
 
Where needed, we make projections guided by statistical inference and modelling guided by one of our co-founders, Dr David Coleman, Emeritus Professor of Demographics at the University of Oxford. We place the highest possible premium on numbers-based analysis, and ensure and encourage a calm and level-headed approach to the facts concerning this paramount issue.
