Lucky Lefty It's Good to be Left-Handed!

How Many People are Left-Handed?

Population of left handed people

Studies vary slightly, but it is thought that about 10% of people are left-handed. The exact worldwide percentage is elusive both because the definition of left-handedness is flexible and because the rate of occurance may vary between cultures. Men are slightly more likely than women to be left-handed. There are also slightly positive correlations between left-handedness and some neurlogical disorders such as autism, dyslexia, and schizophrenia.1

Given a 10% occurance of left-handedness and that there are well over 7 billion people on Earth2, there are over seven-hundred millon (700,000,000) lefties in the world!
