In 2013, Mike Savage and others proposed a new model of class that was no longer based exclusively upon socio-economic status (SES). They suggested seven classes, including a ‘precariat’, ‘emergent service workers’, ‘technical middle class’ and ‘elite’ class. The previous SES version showed a class gradient correlating with health outcomes, and this assocation was generally explained in terms of deprivation and access to health care and health knowledge. Can the new model be used to explain health inequalities, and if so, what is the mechanism?
