Explore the OCID Population

OCID is unique to Oregon, integrating longitudinal data from programs across five state agencies. We invite you to explore the graphs and charts below to gain an understanding of who is included in the OCID population.

OCID Population Growth

The OCID population is defined as Oregon-resident births from 2001 onwards, including infants along with their parents as identified on the birth certificate.* This means the OCID population grows over time, as more children are born into it (thereby adding their parents).
