There are approximately 1.376 billion 'white' people in the world, approximately 20.25% of the world's population.
The number above is calculated from the European and Caucasian populations of the world.
The most significant populations of 'white' people are the Germans (160 million), the Spaniards (152 million), the Italians (140 million), the French (130 million), the English (90 million), the Irish (80 million), the Poles (60 million) and the Ukrainians (50 million).
Not included in this value are the mixed-race persons (numerous in South America).
These numberes ARE completly off. Someone was sleeping in class. :-) Italy has just 60 million, Germans 80 million, France almost 66 million etc etc. Incidently the Caucasions are located in all Europe, all north Africa and middle East including Iran, Iraq, Saudi Arabia, Afghanistan, Pakistan, India etc; dont forget Australia (Aborigens are genetically Caucasians). North and south America have the majority of caucasian population compared to the rest. This is not my opinion or politics...these are simply the facts. 1.2 billion as you state are just in India alone.
