US Life Expectancy Data

I took a look at the World Health Organization's data on the at birth life expectancies for various countries in the world.  The number given for each year assumes that levels of mortality will remain roughly the same throughout the individual's life, and it is a summary of the mortality patterns across all individuals in a given population.

From the WHO's global data I excised the data relating specifically to the United States.  After plotting the data and fitting a regression line, it's pretty clear that so far the US life expectancy exhibits a linear rate of increase, growing from about 69 years in the early 1960's to around 79 years today.
