Hand Difference Statistics
The term ‘hand difference’ includes a wide range of diversities in hands and/or arms. It can include upper limb differences that people are born with (congenital), and upper limb differences that are acquired throughout life.
The causes of congenital hand differences are multifactorial, meaning that they can be caused by many different environmental and biological interactions. Most hand differences happen simply by chance. According to statistics in Australia, around 600 babies are born with a hand difference each year.
