 #### MOUD types within 30-min drive (impedance-adjusted)
 MoudTyp counts how many different MOUD types (buprenorphine, methadone, naltrexone) are available within a 30-minute car drive, after applying the impedance factor (Minutes2). Because Minutes2 (impedance) = 2 × Minutes, this 30-minute threshold with impedance is roughly equivalent to a 60-minute drive under ideal conditions. This variable is built from the three binary indicators BupCntDr2, MetCntDr2, and NaltCntDr2 for each census tract, and is available only for 2025 tract-level measures.
 
+#### RAAM Access Measures
+We calculated RAAM access metrics for census tracts using tract centroids as demand locations, tract-level population as demand, provider counts per tract as supply, and national car travel-time matrices up to 90 minutes. RAAM iteratively allocates demand to nearby providers within a specified travel-time budget while accounting for both travel impedance and provider crowding, and returns an access cost for each tract. Lower RAAM values indicate better access, while higher values indicate worse access. In the current release, RAAM measures are available only for methadone and opioid treatment programs (OTP); This analysis was conducted in Python using the PySAL access package, with complete computational notebooks which can be found here - [scripts/RAAM_National_OTP.ipynb] (https://github.com/healthyregions/oeps/blob/main/scripts/RAAM_National_OTP.ipynb)
+
+A null value indicates that a RAAM score was not available for that geography in the current release. This may reflect no reachable provider within the modeled travel-time threshold, missing required inputs, or a value not produced during processing or integration.
