NOTE: Census tract and ZIP code-level maps are only as accurate as the address information provided on the birth certificate. At least 95 percent of births recorded in Oregon contain sufficiently accurate address information to be geocoded at the level of residential address or street. For border counties, where residents regularly give birth in neighboring states, the accuracy of residential address information is dependent on that state's data collection procedures.
