Footnotes ...
| <1> | If you're interested in how the shape of Illinois' counties, including Will, have changed over time, we recommend the Atlas of Historical County Boundaries. |
| <2> | An 'estimated' location is one where we have been given GPS coordinates, but are unable to verify the accuracy of those coordinates. That said, we have some confidence that we have placed the marker near the actual location. A typical reason for being unable to verify a location is that it might be on private property or maybe historic and gone without an obvious trace. |
| <3> | The pronunciation we've provided is our attempt to give a phonetic pronunciation for Wilmington. While it might not be exactly right, hopefully it will be close. If we have it wrong or there's a better way to pronounce the name, please contact us through our Feedback Page. |
| <4> | 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 Wilmington 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 Wilmington may use one name, keep in mind that others may use something different. |
| <5> | Population counts have been provided by the U.S. Census Bureau. For more detail, please visit our Census Page for Wilmington. |
| <6> | The elevation is an estimate for the area around Wilmington - it will be higher in some places and lower in others. |
| <7> | 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 Wilmington). When looking for a ZIP Code, whether Wilmington or elsewhere, it's always best to check the website of the United States Postal Service (USPS). |
