Footnotes ...

<1>	We use the term 'Historic' broadly and it generally means that the community no longer exists. However, it can also mean that the community might still exist, but was significantly larger or had a more 'official' existence in the past than it does now. Unfortunately our sources of data have proven to be unreliable. If you can provide us with more specific information about Sullivan Center, please let us know so that we can improve our accuracy.
<2>	The pronunciation we've provided is our attempt to give a phonetic pronunciation for Sullivan Center. 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.
<3>	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 815 code has been Overlayed with the 779 area code. New phone numbers in the Sullivan Center area will be assigned with one of these codes: 815 or 779. As a result, placing a call in the Sullivan Center area will require 10-digit dialing (where you enter both the area code and then the phone number).
<4>	The elevation is an estimate for the area around Sullivan Center - it will be higher in some places and lower in others.
<5>	Longitude & latitude values may not be the geographic center of Sullivan Center, rather it may be a prominent intersection or the center of population, etc. It will vary depending on the source.
<6>	Name of the USGS 7.5 Minute topographic map which includes Sullivan Center.
<7>	Every year, the US Census Bureau creates a population estimate for the preceeding year. Keep in mind that this value is an estimate and not an actual count. The most recent Census estimate is for the year 2019.
<8>	The area value has been supplied by the US Census Bureau and it can be different than the geographic boundaries of Sullivan Center. The value given by the Census Bureau reflects their statistical (or sampling) requirements. For example, if there is a cluster of people living just outside of the community's official boundary, the Census-defined area might be expanded to include that group.
<9>	A Housing Unit is a broad term for those places where people live (whether occupied or temporarily vacant), such as a house, an apartment, a mobile home, or an area that is considered as a separate living quarter. Separate living quarters (consisting of one or more rooms) are considered to be those places where people live, sleep and eat separately from others and that have access to the outside (either directly or by a shared hallway).
