After a 2005 survey of over 200 chiropractic practices, researchers revealed the average chiropractic patient is a 44-46 year old female with back pain. Back pain accounted for 41-46% of chief complaints with other common complaints including neck pain and headaches. The average patient either sought out care on her own (self-referral) or was referred by a friend, family member, or acquaintance.
