Date of dataset: 6/30/2018
Source: PRISM (Probation Record Information System Management) PO-234 Report
Notes: To ensure confidentiality and to protect the identities of individuals on probation, the ages of some individuals in the dataset have been withheld, and marked “N/A”. This is done to avoid possible re-identification through the available demographic information, or stigmatization of a group when they make a substantial percent of a designated population.
Number of records with ages withheld: 24

The Alameda County Probation Department (ACPD) collects information on all juveniles referred to the department and records this in PRISM (Probation Record Information System Management). Several reports are built into the PRISM system that allow ACPD staff to extract data for specified time periods. This dataset is derived from the PRISM PO-234 report. This report provides a dataset of all youth that have an assigned Probation Officer. Cases include formal supervision, informal supervision, intake, and investigations. The report provides a one-day snapshot of individual-level data on each youth along with demographic information. To create this dataset, the report was de-identified and edited to include the most pertinent information.

Data Characteristics and Known Limitations
• To ensure confidentiality and to protect the identities of individuals on probation, the ages of some individuals in the dataset have been withheld, and marked “N/A”. This is done to avoid possible re-identification through the available demographic information, or stigmatization of a group when they make a substantial percent of a designated population. Please see the “Notes” tab in the public dataset file, which states the number of records with withheld ages in that dataset.
• PRISM is a referral system rather than a case management system, and a youth may have more than one open referral at a time. Therefore, the analyst who creates this report must apply a hierarchy to determine how to count youth with multiple open referrals, since PRISM does not perform this function. The hierarchy employed for this dataset is as follows: Warrant, Placement, Community Supervision, Intake / Investigations, Truancy.
