Anthony John Fox (born 25 April 1946) is a British statistician, who has worked in both the public service and academia.
In 1990, he took on the additional post of honorary professor at the London School of Hygiene and Tropical Medicine.
In 1996, following the creation of the Office for National Statistics (ONS) (into which OPCS was incorporated), cuts in the senior Civil Service meant that his responsibilities were widened to include demographic statistics and he became Director of the Census, Population and Health Group there.
In 2004, he became the "Change Manager" responsible for setting up the new English Information Centre for Health and Social Care (since renamed the Health and Social Care Information Centre), which officially came into existence on 1 April 2005.
The permanent Chief Executive from July 2005 is Professor Denise Lievesley, formerly director of Statistics at UNESCO.
