Footnotes ...

<1>If you're interested in how the shape of Virginia's counties, including Fairfax, 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 Mount Vernon 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 Mount Vernon may use one name, keep in mind that others may use something different.
<3>The elevation is an estimate for the area around Mount Vernon - 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 703 code has been Overlayed with the 571 area code. New phone numbers in the Mount Vernon area will be assigned with one of these codes: 703 or 571. As a result, placing a call in the Mount Vernon area will require 10-digit dialing (where you enter both the area code and then the phone number).
