Footnotes ...
| <1> | 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 city (such as Hayward). When looking for a ZIP Code, whether Hayward or elsewhere, it's always best to check the website of the United States Postal Service (USPS). Our list of ZIP Codes for Hayward includes: 94540, 94541, 94542, 94543, 94544 & 94545. |
| <2> | The elevation is an estimate for the area around Hayward - it will be higher in some places and lower in others. |
| <3> | Every year, the US Census Bureau creates a population estimate for the preceeding year. Keep in mind that this value is an estimate and not an actual count. The most recent Census estimate is for the year 2019. |
| <4> | The area value has been supplied by the US Census Bureau and it can be different than the geographic boundaries of Hayward. The value given by the Census Bureau reflects their statistical (or sampling) requirements. For example, if there is a cluster of people living just outside of the community's official boundary, the Census-defined area might be expanded to include that group. |
| <5> | A Housing Unit is a broad term for those places where people live (whether occupied or temporarily vacant), such as a house, an apartment, a mobile home, or an area that is considered as a separate living quarter. Separate living quarters (consisting of one or more rooms) are considered to be those places where people live, sleep and eat separately from others and that have access to the outside (either directly or by a shared hallway). |
