What is the ratio of right handed to left handed people in the US?

Answer 1

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.

Answer 2

The generally accepted figure seems to be 10% of the world's population. So as a ratio, that's 9 right handed people to 1 left handed person, or 9:1.

Answer 3

Over 90% of the adult population is right-handed. The present population of the US is 300,000,000. You do the math.

Answer 4

Approximately 85-90% of people in the US are right-handed, while 10-15% are left-handed.
