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.
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.
Australia sits with about 10 per cent of the population. In many parts of the world there's still some bias against left-handers – the left hand can be considered dirty (it's usually the one that gets the job of ah, wiping, whereas the right hand is for eating, shaking hands, that sort of thing).
The prevalence of left-handedness has been consistently reported to be lower in Asia compared to Europe and North America [11, 20, 21]. This difference could be explained by both population-specific genetic and cultural factors.
The countries that use right-to-left writing systems are predominantly Arab and Asian and they all have left-handedness rates below 6 per cent. In Muslim countries, the advantage of smudge-free handwriting is outweighed by the fact that the left hand is considered unclean.
In Japan, about one out of every ten people is left-handed. Therefore, left-handed people are the minority in society. There are also people who can only use one side of their body due to physical disabilities.

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.
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.
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. According to research published in the American Journal of Psychology, lefties appear to be better at divergent thinking.
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.
In many Muslim parts of the world, in parts of Africa as well as in India, the left hand is considered the dirty hand and it's considered offensive to offer that hand to anyone, even to help. The discrimination against lefties goes back thousands of years in many cultures, including those of the West.
Ethnic differences in handedness are related to geographi- cal differences, with left-handedness generally being more common in White, Asian and Hispanic populations – a differ- ence seen both in the UK, and historically in the United States, where the difference between ethnic groups has grown smaller during the ...
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.
Our confidence intervals at a 95% confidence level show that the average IQ for a left handed person is between 117.73 and 127.19 and for a right handed person it is between 109.9 and 123.5.

Recessive traits often happen in pairs so commonly people with the gene for red hair also possess the trait for left-handedness.
While some reasons for the differences in thinking and functioning may be genetic and anatomical, left-handedness is behavioral as well. Things left-handers do differently are often influenced by the societal implications of having a dominant hand that differs from the general public.
The answer is - absolutely! Left-handed scissors have reversed blades so that the top blade is always on the left. This makes it easier to see your cutting line and will ensure your hand pushes the blades together correctly.
Only 1 percent of people in China are left-handed, while the global average is 10-12 percent. In 2/3 of the world it's still unlucky to be born a leftie, says a researcher who has taken a new look at attitudes about left-handed people worldwide.
While 5.8% in South Korea are left-handed, China has less than 1%.
Fewer than 3 per cent of people in China report being left-handed, despite the global average being closer to 10 per cent. Researchers think the difference is probably due to a continuing cultural stigma against left-handedness, which is less of an issue elsewhere, rather than genetics.
