Why this section?
When considering the health of people in Missoula County, we can identify many interrelated topics. Health is one of those frequently used words that mean different things to different people; interests and concerns change related to stages of life and circumstances. Health is no longer defined as simply the absence of disease. A broader definition is "the blending of physical, emotional, social, intellectual, and spiritual resources as they assist in mastering the developmental tasks necessary to enjoy a satisfying and productive life." Payne & Hahn 1992
Public health focuses on what we, as a society, do collectively to assure conditions in which people can be healthy. Public health is particularly concerned that some Missoulians are more challenged than others and experience illness, difficulty and death at higher levels. These disparities can be found in all the topics listed below. See Special Populations.
Life Expectancy
Life expectancy is the average number of years people born in a given year are expected to live based on a set of age-specific death rates. At the beginning of the 20th century, life expectancy at birth was 47.3 years. Fortunately, life expectancy has dramatically increased over the past 100 years (see figure 1). Today, the average life expectancy at birth is nearly 77 years

Life expectancy for persons at every age group has also increased during the past century. Based on today's age-specific death rates, individuals aged 65 years can be expected to live an average of 18 more years, for a total of 83 years. Those aged 75 years can be expected to live an average of 11 more years, for a total of 86 years.
