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 Addison, please let us know so that we can improve our accuracy.
<2>	If you're interested in how the shape of Iowa's counties, including Humboldt, have changed over time, we recommend the Atlas of Historical County Boundaries.
