Understanding the population that a hospital supports is an important part of service planning and healthcare provision. Hospital provider trusts do not have geographically defined boundaries for the populations they support. They also do not have comprehensive lists of registered patients.
The Office for Health Improvement and Disparities (OHID) has published modelled estimates of the catchment populations for hospital provider trusts in England. These catchment populations give estimates for the number of people who are using each hospital trust or have the potential to do so.
Catchment populations are useful for service planning and show the potential population who may access the services.
