Growth over the Very Long Run

From the excellent (and long) Capital in the Twenty-First Century by Thomas Piketty.  If you look a the time period 1700-2012 - global output grew at an average annual rate of 1.6% with 0.8% coming from population growth and the remaining 0.8% coming from per capita output growth.  The two P's dominate growth - population and productivity.
