McManus which found that the Netherlands has one of the world's highest prevalences of left-handedness at 13.23 percent. The United States isn't far behind with a rate of 13.1 percent while neighboring Canada has 12.8 percent. Elsewhere, rates of left-handedness are far lower and China is a good example.
The prevalence of left-handedness varies across the world – from 3.5 per cent in China to more than 13 per cent in the Netherlands. Australia sits with about 10 per cent of the population.
There are no left-handers in China, the world's largest country. Plenty of Chinese are born left-handed—probably about 10-12 percent of the population, based on statistics from other countries—but they aren't allowed to stay that way.
In fact, one of the more unusual hypotheses to explain the rarity of left-handedness is that a genetic mutation in our distant past caused the language centres of the human brain to shift to the left hemisphere, effectively causing right-handedness to dominate, Alasdair Wilkins explains for io9 back in 2011.
This indicates that if females had a chance of being left-handed of exactly 10 percent, males would have a 12 percent chance (the exact percentages vary a bit depending on geographical region). Given the low incidence of left-handedness in general, this 2 percent increase is quite a substantial difference.
Babe Ruth. The Babe is probably the most famous left-handed slugger of all-time.
Left-handed people are said to be good at complex reasoning, resulting in a high number of lefty Noble Prize winners, writers, artists, musicians, architects and mathematicians.
Abstract. Left-handedness occurs in about 8% of the human population. It runs in families and an adoption study suggests a genetic rather than an environmental origin; however, monozygotic twins show substantial discordance.
In Japan, about one out of every ten people is left-handed. Therefore, left-handed people are the minority in society.

Although the percentage varies worldwide, in Western countries, 85 to 90 percent of people are right-handed and 10 to 15 percent of people are left-handed. Mixed-handedness (preferring different hands for different tasks) and ambidextrousness (the ability to perform tasks equally well with either hand) are uncommon.
Research suggests that between ten and twelve percent of the world's population is left-handed. Even though being left-handed might mean struggling with right-handed scissors from time-to-time, there are plenty of reasons being a lefty is pretty cool!

Sex – slightly more boys than girls are left-handed. This suggests to some researchers that the male hormone testosterone has an influence on right and left-handedness. Fetal development – some researchers believe that handedness has more of an environmental influence than genetic.
For example, if both parents are right-handed, there is a 1 in 10 chance of having a left-handed child. If the father is left-handed, the odds are 2 in 10. If the mother is left-handed, the odds rise to 3 in 10.
Blondes are twice as likely to be left-handed than brunettes or redheads. Left-handers generally wear their wristwatch on the right arm.
Special or not, lefties are born, not made: Genetics are at least partially responsible for handedness. Up until last year, it was assumed that hand preference comes from asymmetrical genes in the brain—two hands, two brain hemispheres, one is dominant.
First Chronicles 12:2 seems to reference bowmen who were ambidextrous. When the Bible refers to left-handed people, it speaks of left-handedness as an advantage, not a weakness. While it is not as honorable as sitting at someone's right hand, sitting at the left hand is still a position of honor.
Overall, individuals with ADHD had a 27.3 percent chance of being either left-handed or mixed-handed compared to 18.1 percent in the general population. So the results suggest that the effects are smaller than for the autism spectrum, but generally go in the same direction.
Queen Elizabeth II is left-handed.
?♀️ Queen Victoria is one of the most famous historical lefties. Although she wrote with her right hand, she painted with her left, which indicates she was made to switch as a child, as was sadly common in the Victorian era."
It is found that, using three different measures, left-handers are significantly more likely to have depressive symptoms that right-handers. For example left-handers are about 5% more likely to have reported having ever experienced symptoms of depression compared to about 27% of the total sample.
