Footnotes ...

<1>	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 Eureka 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 Eureka may use one name, keep in mind that others may use something different.
<2>	The elevation is an estimate for the area around Eureka - it will be higher in some places and lower in others.
<3>	The Canadian Postal Code consists of 6 characters, where the first three characters are the 'Forward Sortation Area (FSA)', with the last three characters being the 'Local Delivery Unit (LDU)'. In the case of Eureka, we provide only the FSA and not the LDU. The Canadian Postal Codes were created as a way of grouping addresses to make delivery more efficient. So keep in mind that any given Postal Code is only 'loosely' associated with a community (such as Eureka). The boundaries of the Postal Code can be changed, re-assigned, eliminated or overlapped with other Postal Codes. When looking for a Postal Code, whether Eureka or elsewhere, it's always best to check the website of the Canada Post / Postes Canada.
