More or Less - 17/09/2010

Tim Harford and the More or Less team investigate the numbers around us. Who earns more: private or public employees? We examine new headline-grabbing Office for National Statistics figures. As the Pope visits Britain, we investigate contested estimates of the number of Catholics who attend mass. Are your trousers flattering you? We find out whether high street chains are guilty of "vanity-sizing". And More or Less sends its own runners to the Great North Run, in an attempt to measure how age and sex affect sporting ability.
