Abstract
The surgical experience of a sample of people aged 40-64 randomly selected from general practice lists was elicited by means of a postal questionnaire and the results examined in relation to two indicators of socioeconomic status. Eighty per cent of the sample had had one or more surgical operations and women had a higher mean number of operations than men. Those in the more advantaged groups had a higher mean number of operations than those in the less advantaged groups. This difference was, however, mainly accounted for by operations carried out in childhood before the establishment of the National Health Service and by private sector surgery.
