Industry Definition & Overview
Offices of Chiropractors (NAICS 621310) encompasses establishments of health practitioners having the degree of D.C. (Doctor of Chiropractic) primarily engaged in the independent practice of chiropractic per the U.S. Census Bureau[5]. Chiropractors perform spinal adjustments, musculoskeletal manipulation, and related therapies to treat back pain, neck pain, headaches, and joint disorders. Practices operate as solo offices, group practices, and franchise-based clinics providing outpatient care without prescription medication or surgical intervention.
Roughly 74,200 establishments employ 137,400 workers and generated $13.4 billion in revenue in the most recent Census year per the Bureau of Labor Statistics[6] and Census data. The Joint Chiropractic operates as the nation's largest franchise network with over 900 locations using a direct-pay, non-insurance model. Chiro One Wellness Centers, HealthSource, and AlignLife maintain smaller but growing franchise systems. Independent solo practitioners continue to represent the majority of the market, though franchise-based models are gaining share.
Per the SBA Table of Size Standards[7], the size standard is $12.5 million in average annual receipts. Chiropractors are licensed in all 50 states, the District of Columbia, and U.S. territories, with education requirements including a four-year Doctor of Chiropractic degree from an accredited program following at least two years of undergraduate study. All states require passage of the National Board of Chiropractic Examiners examination, and 45 states require additional state-specific testing. Scope of practice varies by state, with some jurisdictions permitting adjunctive therapies such as acupuncture and physiotherapy alongside manual spinal adjustment.
