A population health approach can be defined as a subset of public health with a whole-of-population focus, 42 or as containing both public health and other health services. 43 Population health is not the only term that is sometimes misleadingly 39 An alternative would be to include both terms in the domain name. 40 Lalonde 1974. 41 Hayes & Dunn 1998. The population health approach is not without its critics, some of whom argue that it has been captured by the focus on the problems of individuals (e.g. overweight persons), while losing sight of the larger issues (e.g. obesogenic environments) (Raphael & Bryant 2002) . 42 Bennett 2003: 12. 43 For instance, a 'population health approach describes a comprehensive health system which ranges from public health at one end to individual health care at the other' (Buckett & Hunter 2004) . Fraser (2005) conceptualises population health as 'the health of a defined population, or a field of study that links health outcomes, determinants of health, and interventions' but notes that it is an 'ill-defined term' in the literature. The term public health has competing definitions, but is considered by many health professionals to be 'broader and more encompassing than population health' (Fraser 2005: 177) .
