When the Census Bureau conducts a census for a town like Avon, they draw a boundary around the area in which they are going to conduct their count - this is called a sampling area (or 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 town.
Things like the population, area and housing for Avon reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Avon might be slightly different, it's best to check with the U.S. Census Bureau if you need precision.
The 2010 Census shows that the sample polygon for Avon has a total area of 2.67 square miles [6.9 km²]. Of this total, a small amount of the area is covered by water (0.02 square miles [0.1 km²]).
Houston County has a land area of 579 square miles [1,501.7 km²]. At 2.65 square miles [6.9 km²], Avon has 0.46% of the county's total land area.
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 at the center of the polygon). At the time of the 2010 Census, the sampling area was located at:
Lat: 31° 10' 47" (or 31.18°) [Map]
Lon: -85° 16' 45" (or -85.28°)

It's important to note that from one Census to the next, the shape and location of the polygon can change.
If you need precision or details about the methodology of the Census, you should visit the U.S. Census Bureau for a definitive answer.

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).|
