Footnotes ...
| <1> | If you're interested in how the shape of Colorado's counties, including Park, have changed over time, we recommend the Atlas of Historical County Boundaries. |
| <2> | 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 Jefferson refer to themselves. It's important to note that there aren't any rules for taking a community's name and turning it into a demonym. A demonym is informal and while the majority of Jefferson may use one name, keep in mind that others may use something different. |
| <3> | The elevation is an estimate for the area around Jefferson - it will be higher in some places and lower in others. |
| <4> | ZIP Codes have been created by the United States Postal Service (USPS) as a way of grouping addresses to make delivery more efficient. The boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes. So keep in mind that any given ZIP Code is only 'loosely' associated with a community (such as Jefferson). When looking for a ZIP Code, whether Jefferson or elsewhere, it's always best to check the website of the United States Postal Service (USPS). |
