Objective: To examine whether the sociodemographic and morbidity characteristics of populations influence their use of the following community health services: district nursing, health visiting, chiropody, community maternity, community mental illness, and the professions allied to medicine. Design: Observational study. Setting: Nationally representative sample of provider trusts in England. Main outcome measures: Activity levels for each service calculated for enumeration districts within the catchment areas of the sample of trusts and standardised to allow for differences in age structure. Regression analysis to determine whether the standardised activity rates for each service could be predicted by a range of socio-demographic and morbidity proxies. Results: Morbidity or deprivation, or both, seemed to influence the use of services in each of the care programmes examined. Conclusions: The allocation of funds for community health services should allo iv for differences in the health and socio-demographic characteristics of health authorities.
