Footnotes ...

<1>If you're interested in how the shape of Oregon's counties, including Multnomah, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>A demonym is the name for a resident of a community which is usually derived from (or is related to) the name of that community. In other words, it's how the residents of Oneonta refer to themselves. It's important to note that there aren't any rules for taking a community's name and turning it into a demonym. A demonym is informal and while the majority of Oneonta may use one name, keep in mind that others may use something different.
<3>The elevation is an estimate for the area around Oneonta - it will be higher in some places and lower in others.
<4>When there's a risk of an area code running out of phone numbers, an 'Overlay Area Code' is created that has the same geographic boundaries as the existing area code. In this case, the 503 code has been Overlayed with the 971 area code. New phone numbers in the Oneonta area will be assigned with one of these codes: 503 or 971. As a result, placing a call in the Oneonta area will require 10-digit dialing (where you enter both the area code and then the phone number).
