The number of employed health care personnel in an area is the combined result of factors affecting both demand and supply for health care personnel. When service areas are compared, differences between each area's number of health care personnel are related to differences in health facilities' ability and desire to attract these persons.
At any point in time, the potential supply of health care personnel is fixed. The choice facing this segment of the labor force is between alternative locations or non-participation. The location decision is a function of salary, working conditions and such non-working conditions as cost of living in the community, schools, cultural opportunities, employment opportunities for other family members and general amenities associated with a community.
