Life expectancy at birth is a summary measure that describes the average number of years a newborn baby can be expected to live if current death trends continue. For people already living, life expectancy is dependent on their age, and will vary.
For the years 2000 to 2004, life expectancy at birth for Simcoe Muskoka males was 77.1 years and 81.6 years for females. In comparison, the life expectancy at birth for Ontario males was 77.6 years and 82.2 years for females.
