The assignment of Person identifier to a uniquely identifiable individual is important for the Community Mental Health Care (CMHC) NMDS to permit the determination of the number of clients receiving services within a jurisdiction. The ability of jurisdictions to generate unique identifiers varies, as described in the data quality statement for the CMHC NMDS.
