The life expectancy for a child born between 2012 and 2016 in Mason County is 79.1 (2). Meaning a person born in Mason County between 2012 and 2016 can be expected to live 79.1 years on average. In comparison, the life expectancy for the state of Washington for that same period was 80.3 years (2). Mason County’s life expectancy rate is increasing over time; between 1993 and 1997 the life expectancy for a newborn child was 75.3 years (2). The top 3 leading causes of death for both males and females in Mason County are cancer, heart disease and unintentional injury, in that order (3). Mason County has higher mortality rates due to cancer, unintentional injury, chronic obstructive pulmonary disorder (COPD), and chronic liver disease (3).

The cancer type that results in the most deaths in Mason County is lung cancer. Between 2007 and 2016 the age-adjusted mortality rate as a result of lung cancer was 53.2 deaths per 100,000 or 480 deaths. Mortality rates associated with Alzheimer’s are lower in Mason County; while death rates associated with heart disease, stroke, diabetes and suicide are similar to the state’s rates (3). Although Mason County experiences approximately only 3 child deaths per year, the childhood mortality rate is also higher than the rate for the state (3). 


Health outcomes are also determined by community morbidity measures (1). Morbidity describes how healthy individuals feel. Mason County adults report more poor health days, due to either physical or mental health conditions compared to other adults in the state (5).

Many of the leading causes of death and chronic health conditions are caused or exacerbated by unhealthy lifestyle behaviors. Behaviors such as lack of physical activity, poor nutrition, and sedentary lifestyle can lead to higher incidences of obesity. In addition to being the second leading cause of death in Mason County, heart disease was the leading cause of hospitalizations; resulting in 3,111 hospitalization events between 2011 and 2015 (3,4).

Smoking behaviors can also increase a person’s risk of illness. Both Mason County adult and youth populations have higher smoking rates when compared to states rates (5,6). However, smoking rates have decreased over time (5,6).
