Footnotes ...
| <1> | If you're interested in how the shape of Wisconsin's counties, including Vernon, 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 Ontario refer to themselves. It's important to note that there aren't any rules for taking a village's name and turning it into a demonym. A demonym is informal and while the majority of Ontario may use one name, keep in mind that others may use something different. |
| <3> | Population counts have been provided by the U.S. Census Bureau. For more detail, please visit our Census Page for Ontario. |
| <4> | The elevation is an estimate for the area around Ontario - it will be higher in some places and lower in others. |
| <5> | 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 608 code has been Overlayed with the 353 area code. New phone numbers in the Ontario area will be assigned with one of these codes: 608 or 353. As a result, placing a call in the Ontario area will require 10-digit dialing (where you enter both the area code and then the phone number). |
| <6> | The location has been supplied by the Geographic Names Information System - which is maintained by the U.S. Geological Survey (USGS). While these values should be definitive, we found that accuracy can vary and you should double-check the location if accuracy is required. |
