When the Census Bureau conducts a census for a community like Waterville, 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 community.
Things like the population, area and housing for Waterville reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Waterville 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 Waterville has a total area of 36.18 square miles [93.7 km²]. Of this total, 35.64 square miles [92.3 km²] is land, with the balance (1.51%) being water (0.55 square miles [1.4 km²]).
Pepin County has a land area of 232 square miles [600.8 km²]. At 35.64 square miles [92.3 km²], Waterville has 15.36% 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: 44° 38' 5" (or 44.63°) [Map]
Lon: -92° 2' 50" (or -92.05°)

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).|
