what percent of the population is left handed

According to multiple sources, about 10% of the worlds population is left-handed. This percentage has remained relatively consistent over time, with early estimates ranging from 1% to nearly 30% . However, the most reliable answer to date comes from the largest survey ever conducted in 1994, which was done in 32 countries and found that 9.5% of people worldwide reported using their left hand to write, with some variation from country to country. It is worth noting that handedness is often defined by ones writing hand, as it is fairly common for people to prefer to do a particular task with a particular hand.
