Moreover my reference to the population growth rate was indeed valid. GDP per capita, using purchasing power parity statistics, DECLINED during the Carter Presidency.
Wait, what am I, chopped liver? Didn't I just calculate this
, and discover that Real GDP growth over the four years Carter was president was significantly higher than the population growth?
That was based on the Real GDP growth numbers Parados provided, though, and my own calculation. So let's Google GDP (PPP) per capita, specifically.
This is from an online encyclopedia
about which I know little, but it cites the World Bank's World Development Indicators database as source:
1976 - United States: 8,300.502 PPP $ per capita
1980 - United States: 12,185.719 PPP $ per capita
Looks like a firm increase to me.
Just to doublecheck this .. here: The Penn World Table
, provided by the Center for International Comparisons of Production, Income and Prices
at the University of Pennsylvania, "provides purchasing power parity and national income accounts converted to international prices for 188 countries for some or all of the years 1950-2004."
Here's the data for the relevant years regarding Real GDP per Capita (and the site adds: "Please note: in PWT, "real" means "PPP converted""):
USA 1976 8,277.93
USA 1977 9,132.09
USA 1978 10,218.79
USA 1979 11,303.56
USA 1980 12,170.33
Again, a firm increase .. of 14.7%, actually, over those four years.
So what gives? If you were going on memory, maybe this is a good sign that your assumptions might benefit from some revising?
