When the Census Bureau conducts a census for a town like Ridgeville, 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 Ridgeville reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Ridgeville 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 Ridgeville has a total area of 0.82 square miles [2.1 km²].
Etowah County has a land area of 534 square miles [1,385.6 km²]. At 0.82 square miles [2.1 km²], Ridgeville has 0.15% 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: 34° 3' 24" (or 34.06°) [Map]
Lon: -86° 6' 10" (or -86.1°)
