- When the Census Bureau conducts a census for a city like East Ridge, they draw a boundary around the area in which they are going to conduct their count - this defines the sampling area (usually a polygon). The shape of the sampling area can be quite complex and it's important to keep in mind that the boundaries of the sampling area may or may not match the recognized boundaries of the city.
- Things like population, area and housing for East Ridge reflect the sampling area. Since the shape of the sampling area and the actual boundaries of East Ridge might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.
- Not only does the sampling area define boundaries, it also has a GPS location (latitude & longitude) that indicates a point within the sampling area (usually the center of the polygon, known as the centroid). At the time of the 2010 Census, the sampling area was located at:
- Lat: 34° 59' 50" (or 35°)
- Lon: -85° 13' 42" (or -85.23°)

- Note: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2010 Census and the 2000 Census, there were changes in the sampling area for East Ridge and you need to be careful when comparing results between the censuses. More information about these differences can be found in the section called Census-to-Census Observations ... (see below).

This area (or sampling area) is a polygon and its shape can be quite complex - it may or may not match the geographical boundaries of East Ridge. It's important to note that from one Census to the next, the shape and location of the polygon can change.

|<1>||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.|
|<2>||Every 10 years (eg- 1990, 2000, 2010), the US Census Bureau conducts a Constitutionally-mandated count (or enumeration) of people living within the United States. This count is called a Decennial Census. The last Decennial Census was the 2010 Census, with the next one planned for 2020.|
|<3>||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).|
