Footnotes

<1>	Population counts have been provided by the U.S. Census Bureau. - Return to Citation
<2>	Our distances are calculated as a straight-line (or point-to-point) distance between Rockford and the indicated community. The distance should be treated as an estimate and not as the driving distance. - Return to Citation
<3>	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). - Return to Citation
<4>	The area value has been supplied by the US Census Bureau and it can be different than the geographic boundaries of Rockford. 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 of people. - Return to Citation
<5>	The communities in our count are those provided by the 2000 Census, so keep in mind that our population rings will only include the people living in those communities. Smaller communities usually don't participate directly in the Census and therefore they won't be included. While our count is a close approximation, it shouldn't be considered as a complete or accurate count. - Return to Citation
