The demand for healthcare services is driven by both consumption and investment motives. As consumption goods, healthcare makes people feel better, and as investment goods, better health increases productivity. Patients rely on healthcare professionals to evaluate their needs and make decisions. Demand is influenced by income, price, education, marital status, age, gender, access to facilities, household size, and insurance coverage. Higher incomes, education, prices, and insurance increase demand, while single and older individuals also tend to use more services.
