Footnotes ...

<1>If you're interested in how the shape of California's counties, including Riverside, 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 Riverside refer to themselves. It's important to note that there aren't any rules for taking a city's name and turning it into a demonym. A demonym is informal and while the majority of Riverside 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 Riverside.
<4>The elevation is an estimate for the area around Riverside - it will be higher in some places and lower in others.
