Generating the Wealth of Nations 34: Real GDP per Capita in South Africa
Unless I'm missing something, the Maddison Project data do not seem to include South Africa. If you'd like real GDP per capita data for South Africa from 1969 to 2011, you can find it here:
And here's a chart:
(Click to enlarge.)
Over the 1969-2011 period, growth in real GDP per capita averages 0.7% per year. That, of course, incorporates the decline from 1969 to 1993. From 1993 to 2011, growth averaged 2.2% per year. From 1969 to 1981 (when the decline began), growth averaged 1.1% per year.
UPDATE: I found the Maddison Project data, where there is a continuous data run from 1924 to 2011. Growth was +2.2% per year from 1924 to 1981; -2% per year from 1981 to 1993, and +2.2% per year from 1993 to 2010. (I got fooled because it was listed as "Cape Colony/South Africa." Sigh.)
