Footnotes ...

<1>If you're interested in how the shape of Illinois' counties, including Madison, 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 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 Troy 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 Troy 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 Troy.
<5>The elevation is an estimate for the area around Troy - it will be higher in some places and lower in others.
