In the United States, an estimated 3.3 million people use wheelchairs, including 1.8 million who are aged 65 or older. There are approximately 2 million new wheelchair users per year. Globally, an estimated 131 million people (1.85% of the total population) require a wheelchair for a wide range of reasons.
Wheelchairs provide increased mobility and independence for users and allow them to take part in normal activities, despite their reduced mobility. The power wheelchair is a more recent invention, which has a number of additional benefits for users, including the ability to travel without experiencing fatigue. Power wheelchairs also offer greater independence to people with disabilities that limit their arm strength or movement.
