Which factor does NOT influence the demand for health care services?

Travel distance to service providers is typically viewed as a logistical consideration rather than a direct influencer of demand for health care services. Demand for health care services is generally influenced by various factors, such as the ability to afford care (income), the health status of the population, and the price of services.

When income increases, individuals are often more willing and able to purchase health care services, as they can afford more extensive or higher-quality care. Similarly, the overall health status of the population can affect demand; for instance, if a community has a higher prevalence of chronic illnesses, the demand for health care services will likely increase. Additionally, the price of services directly impacts demand; as prices rise, consumers may choose to forgo or substitute less expensive options for their health care needs.

While travel distance can have an indirect effect—affecting a person's ability to access health care—it is not a primary demand factor itself. Instead, it may serve as a barrier or facilitator to accessing services rather than determining the desire for those services when other factors, like income or price, are considered.
