Epidemiology
Carpal tunnel syndrome can affect anyone. It accounts for about 90% of all nerve compression syndromes. In the U.S., roughly 1 out of 20 people will suffer from the effects of carpal tunnel syndrome. Caucasians have the highest risk of CTS compared with other races such as non-white South Africans. Women suffer more from CTS than men with a ratio of 3:1 between the ages of 45–60 years. Only 10% of reported cases of CTS are younger than 30 years. Increasing age is a risk factor. CTS is also common in pregnancy.

Occupational
As of 2010, 8% of U.S. workers reported ever having carpal tunnel syndrome and 4% reported carpal tunnel syndrome in the past 12 months. Prevalence rates for carpal tunnel syndrome in the past 12 months were higher among females than among males; among workers aged 45–64 than among those aged 18–44. Overall, 67% of current carpal tunnel syndrome cases among current/recent workers were reportedly attributed to work by health professionals, indicating that the prevalence rate of work-related carpal tunnel syndrome among workers was 2%, and that there were approximately 3.1 million cases of work-related carpal tunnel syndrome among U.S. workers in 2010. Among current carpal tunnel syndrome cases attributed to specific jobs, 24% were attributed to jobs in the manufacturing industry, a proportion 2.5 times higher than the proportion of current/recent workers employed in the manufacturing industry, suggesting that jobs in this industry are associated with an increased risk of work-related carpal tunnel syndrome.
