Life expectancy for females was consistently higher than life expectancy for males. In 2014, the difference in life expectancy between females and males was 4.8 years, the same as in 2013.
Life expectancy at age 65 for the total population was 19.3 years, the same as in 2013. Life expectancy at age 65 was 20.5 years for females, unchanged from 2013, and 18.0 years for males, a 0.1-year increase from 2013. The difference in life expectancy at age 65 between females and males decreased 0.1 year, to 2.5 years in 2014 from 2.6 years in 2013.
