The Oregon Child Integrated Dataset (OCID) is a powerful resource for examining the well-being of Oregon’s children.
- OCID is integrated, matching data from 5 state agencies and associated programs to allow insights into the experiences and outcomes for Oregon’s children and birth parents when available. (See sidebar)
- OCID is longitudinal, including program and service data beginning in 2001 and growing each year with annual contributions from its data partners.
- OCID is flexible, allowing two complementary approaches to population-level research and analysis: (1) longitudinal research on data matched to children born in Oregon and their birth parents; and (2) cross-program research using integrated data for all Oregon children served by programs and services.
OCID Population
OCID is uniquely structured to explore the dynamic and diverse experiences of Oregon children from birth through high school graduation age. The OCID population includes:
- All children beginning in 2001 with an Oregon birth record; and,
- Children not born in Oregon but served by OCID-participating state agencies and programs.
The table below provides examples of the program enrollment included in OCID. In calendar year 2022, nearly 833,000 children under the age of 18 resided in Oregon. The school-aged population (5-17 years) was nearly 640,000, of which, approximately 86% or 553,000 students attended public schools. All or almost all of public school, Medicaid/CHIP, and foster care enrollment is included in OCID.

OCID Data Integration
The OCID data integration process begins with state agencies/programs submitting participant data to Integrated Client Services (ICS), a shared Oregon DHS/OHA resource. ICS matches individuals across datasets based on personal identifiers (e.g. name, date of birth, and zip code) and creates a unique study identifier for each person. The study identifier is added to each dataset, and personal identifiers are stripped before the program data are delivered to the Center for Evidence-based Policy.
Data Use Agreements
The Oregon Child Integrated Dataset (OCID) was established through standardized data use agreement (DUA) terms and language to ensure consistency and stability across agency agreements for multiple years. Currently, OCID receives data from the following agencies: Oregon Health Authority, Oregon Department of Education, Department of Early Learning and Care, Oregon Department of Human Services, and Oregon Youth Authority.
The duration of each agreement is five years, with annual or semiannual data refreshes depending on the source.
OCID does not contain identifiable protected information, and the project’s research protocol falls under the regulatory oversight of the Oregon Health & Science University (OHSU) Institutional Review Board. To protect the identities of individuals in the OCID population, and in adherence to data use agreements covering release of the data, results are suppressed if they do not meet minimum reporting thresholds. Criteria for public reporting include:
- Numerator > 10 (or equal to 0, if the denominator is also 0)
- Denominator > 50 (or equal to 0, in which case “NULL” is displayed)
