Footnotes ...

<1>If you're interested in how the shape of Missouri's counties, including Saint Louis, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>The location has been supplied by the Geographic Names Information System - which is maintained by the U.S. Geological Survey (USGS). While these values should be definitive, we have found that accuracy can vary and you should double-check the location if accuracy is required.
<3>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 Eureka refer to themselves. It's important to note that there aren't any rules for taking a city's name and turning it into a demonym. A demonym is informal and while the majority of Eureka may use one name, keep in mind that others may use something different.
<4>Population counts have been provided by the U.S. Census Bureau. For more detail, please visit our Census Page for Eureka.
<5>The elevation is an estimate for the area around Eureka - it will be higher in some places and lower in others.
<6>ZIP Codes have been created by the United States Postal Service (USPS) as a way of grouping addresses to make delivery more efficient. The boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes. So keep in mind that any given ZIP Code is only 'loosely' associated with a city (such as Eureka). When looking for a ZIP Code, whether Eureka or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
<7>Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Eureka) to Point B.

If you need the driving distance, we recommend that you use one of the Mapping Services listed on our Map Page for Eureka. Since we usually use Google Maps for our own planning, we've provided the following link: Google Map and Driving Directions starting from Eureka

Our distance measurements begin at a specific point in Eureka. The point we use is located at these GPS coordinates - Latitude: 38.5015, Longitude: -90.6491       In this case, the coordinates for Eureka have been provided by the Geographic Names Information System (GNIS).
