Erewhon has a population of 5 million people. It is a population with an age distribution typical of most developed countries with about 15% of the population over the age of 65, and the population is ageing. Most live in cities, with two big cities each with a medical school, and city living is increasing and there are some thriving towns and some depressed industrial areas and large sparsely populated rural areas.
The economy of Erewhon is improving slowly but taking into account the impact that population ageing has on health and social care; it is wise to work on the assumption that there will be no real increase in resources available for health and social care. The population of Erewhon is covered by a payment system that is based on combination of tax and insurance but the responsibility for health services is discharged to 10 geographical areas each with a budget taking into account age and deprivation. They have the responsibility for resource allocation; the responsibility for health service provision is based primarily on programmes and systems. Each of the populations, served by the Health Boards called A-J, happen to have a hospital, largely for historical reasons, with two of them being larger teaching hospitals and there are ten Mental Health Services and about 50 general practice teams in each.
