HEART disease remains the biggest killer in the region with the latest figures showing it's responsible for at least 12 per cent of deaths.
The rates of death from chronic obstructive pulmonary disease (COPD, or lung disease) and stroke are also running higher in Cowra, Forbes and Parkes than the national average.
To compare causes of death by local government area and across the nation, the Australian Institute of Health and Welfare (AIHW) had the grim task of counting 790,538 deaths from 2014-18.

Heart disease accounted for 12.6 per cent (61 people) of all deaths in the Forbes LGA and 12.3 per cent (93 people) in Parkes.
