Methodology
Every number on this page is calculated directly from public records; no figure is estimated or written by hand.
Facilities are the treatment locations listed in SAMHSA's FindTreatment.gov locator, each counted once by its listing ID. Closed listings are excluded; active and unconfirmed listings are included (unique IDs; closed excluded; active and unconfirmed included).
Density divides the number of listed facilities by the 2020 Census resident population and multiplies by 100,000.
A treatment desert is a county with zero listed facilities. Facilities are placed in counties by their coordinates against Census county boundaries; deserts are only reported when every listed facility in the state has a verified county.
The Medicaid share is the number of listed facilities that report accepting Medicaid divided by all listed facilities; facilities that do not report it count as not confirmed.
Distances are straight-line (great-circle) miles from a county's Census reference point to the nearest geocoded listed facility in any state. They are not driving distances.
These are listed facilities, not capacity or quality: counts describe listings, not beds, wait times, outcomes or proof of access to care.
