10 percent
About 10 percent of the population is left-handed. The rest are right-handed, and there are also about 1 percent who are ambidextrous, which means they have no dominant hand. Not only are lefties outnumbered about 9 to 1 by righties, there are health risks that appear to be greater for left handers, too.
Is it rare to be left and right-handed?
But because lefties are comparatively rare, most children of left-handed parents are right-handed. Cultural influences, environment, and prenatal exposures may also play a role in determining handedness.
Do left handers have a higher IQ?
No differences in mean IQ scores were found between right-handers and non-right-handers as well as between right-handers and mixed-handers. No sex differences were found. Overall, the intelligence differences between handedness groups in the general population are negligible.
What percentage of left handers are male?
Writing is not as precise an indicator of handedness as it might seem, because many left-handed people write with their right hand but use their left hand for other tasks.

Why is it so rare to be left-handed?
Most of the current research suggests that left-handedness has an epigenetic marker — a combination of genetics, biology and the environment. Because the vast majority of the population is right-handed, many devices are designed for use by right-handed people, making their use by left-handed people more difficult.
Are lefties lucky?
Left-handed people are considered lucky, indeed. Although, in the past, it was considered such an anomaly that left-handed children were forced to use their right hand. But being left-handed can actually be beneficial.

How many people are left handed or right handed?
Scientist hypothesizes that between 70-95% of Earth’s population are right-handed, and the remaining 5-30% are left-handed. Only a couple of percent have an equal strength in both arms. Scientists are positive that inheritance has a huge part, weather the offspring would be right or left armed.
Which is more recessive right handed or left handed?
R = Right-handed gene/allele (Dominant) L = Left-handed gene/allele (Recessive) As probably noticed, the ratio of being right-handed to left-handed is 3:1 3+1 = 4 Thus, thus probability of having a right-handed offspring would b ¾, thereby 75% (4/3 =0,75 0,75*100=75%).
What was the percentage of left handed people in 1860?
For example, in 1860 when a left handed person was essentially seen as being in league with the devil, it is estimated that as little as 2% of the population was left handed. The current 12% figure also varies by country and gender!
