France No official data;
Estimates:
70% ethnic French
15% other European
56,000,000 85% In 2004, Institut Montaigne estimated that "white people of European origin" make up 85% of France's population.
33% of France's population has an immigrant immigrant background (at least one great-grandparent foreign-born). From this we can assume that around 70% of France is still ethnically French.
Slightly less than half of all immigrants for the past 20 years have been from Europe. Assuming they're all Europeans, 70% French + 15% other European = 85% total European for France.

South Africa White: 8.9% 4,586,838 8.9% Data from 2011 Census (Wikipedia)
Not sure what percentage of those who identity as "White" are of purely European descent.

"White" is defined as "A person having origins in any of the original peoples of Europe, the Middle East, or North Africa." (Source)
Because of that, a number of people of purely European descent is probably lower than that.
