Andersen's behavioural model (Andersen, 1968) was created to empirically test hypotheses about inequality of access to health services in the USA. It addresses the concern that some sectors of society - in particular people from ethnic minority groups, people who live in inner cities and people who live in rural areas - receive less health care provision than the rest of the population (Andersen & Newman, 1973). Andersen’s model views access to services as a result of decisions made by an individual, which are constrained by their position in society and the availability of health care services. This model, therefore, allows us to explore hypotheses regarding social inequalities.
