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 Black Rock, please let us know so that we can improve our accuracy.
<2>	Longitude & latitude values may not be the geographic center of Black Rock, rather it may be a prominent intersection or the center of population, etc. It will vary depending on the source.
<3>	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.
<4>	The area value has been supplied by the US Census Bureau and it can be different than the geographic boundaries of Black Rock. 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.
<5>	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).
