The relationship between occupation and population health is complex, but understanding their interrelationships is a policy priority. It is widely accepted that being in employment is associated with health benefits. However, there is a lack of detailed understanding about the relative mortality risks of specific occupations and whether health-related benefits of employment occur across all occupations.
Previous research has quantified the relative importance of specific causes of death by occupation by analysing unlinked death certificates. Such work helps identify the need for occupational health interventions to target those exposed to specific hazards within particular jobs. Existing studies do not allow denominators for the population at risk and therefore proportional mortality ratios, rather than mortality rates, have been calculated (which do not allow comparison between occupations).
The research aim is:
