Approximately 12%
So 12% of 7,000,000,000 (approx)
7,000,000,000/100 = 70,000,000
70,000,000 x 12= 840,000,000 left handers (less than the population of 2 of the world's countries- so not a lot really)
The ratio of left handed people to right handed people is 1:10 and there are around 6,692,030,277 in the world, so that means that around 6 022 827 249 right handed people.
96% of people are right handed
more people are right handed in the world...

About 5% of all right-handed people are gay, the same percentage as the rest of the population.
because of genetics
The same number of years as right-handed people can live to.
They do not. On average, right handed people live 9 years longer than them.
I'm not 100% sure about this, but I have been doing a report on asymmetries betweent the right and left hands and the differences in these asymmetries between right- and left-handers, and from the information I have come across the 1 to 9 ratio seems to be pretty well accepted. (10% left-handed / 90% right-handed). Please correct me if you have more specific or up to date info. I believe ur right about that and of that 10%, 70% are males and 30% are females which means that 90% of the world is right-handed and 10% is left, 7% of the world is left-handed males and 3% is left-handed females. I believe you may be wrong because if 10% of people are left handed then 90% of people are right handed then how many people are ambidextrious? ^The amount of ambidextrous people is assumed to be negligible in this case.

A couple of reasons- evolutionarily, it was easier for right-handed people to survive. Also, many people in older generations who were left-handed were punished for favoring that hand and learned to adapt to using their right. Lefties also die younger- no one know why though.
