These records of the Texas Department of Mental Health and Mental Retardation (MHMR) consist of two volumes of printed monthly population census reports of residents at state mental hospitals, clinics, and schools for the mentally retarded run by MHMR. The reports begin in October in 1965 and go through April 1972. These reports were first compiled by the Department of Biometrics of MHMR, later by the Office of Data Processing, and last by the Office of Program Analysis and Statistical Research. The reports are monthly tabulations of the patient populations at state mental hospitals and schools for the mentally retarded, the number of cases at mental health clinics, and applications for admission to state schools for the mentally retarded. These reports include admissions, transfers, discharges, average daily census, and total populations of state mental hospitals at Austin, Big Spring, Rusk, San Antonio, Terrell, Wichita Falls, Kerrville, and Rio Grande and for state schools for the mentally retarded at Abilene, Austin, Denton, Lufkin, Mexia, Richmond, and the Travis school in Austin. For state mental health clinics at Dallas, Fort Worth, Rio Grande, Austin, Big Spring, Terrell, San Antonio, Wichita Falls, and Rusk the reports include totals for additions and dispositions of cases, number of patients treated and visited, total referrals, and number of new cases.

To prepare this inventory, the described materials were cursorily reviewed to delineate series, to confirm the accuracy of contents lists, to provide an estimate of dates covered, and to determine record types.
