Oregon Birth Data

Updated May 7, 2026

Oregon State law requires birth certificates to be completed for all live births. These birth records are the primary data sources for health information shown on these pages.

Preliminary Birth Data

Preliminary data are undergoing quality assurance and editing procedures that can result in frequent and significant changes. Data can be used for tracking recent health events, but are not appropriate for use in statistical analyses. Final birth data is shown in the next section below.

About Birth Data

The Center for Health Statistics registers only those vital events occurring in Oregon. However, information on births occurring out-of-state to Oregon residents is also reported through an interstate exchange agreement. Data may be tabulated by residence (where the person lived) or by occurrence (where the event occurred).

Please read about Oregon Preliminary Data before using year-to-date and preliminary statistics.
