Dataset Overview

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 8 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 population does not include children who were born outside of the state and not served by the programs and services provided by OCID data partners. 

The table below provides examples of the program enrollment included OCID.  In 2022, nearly 833,000 children resided in Oregon. The school-aged population (5-17 years) was nearly 633,000, of which, approximately 87% or 553,000 students attended public schools. For public education, all or almost all of 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, Oregon Department of Human Services, Oregon Youth Authority, and Integrated Client Services.

The duration of each agreement is four years, with annual or semiannual data refreshes depending on the source. Current agreements last through 2028, and allow for continued analysis of the data for five additional years.

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)
