When the Census Bureau conducts a census for a town like Pine Ridge, 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 Pine Ridge reflect the sampling area. Since the shape of the sampling area and the actual boundaries of&$160;Pine Ridge 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 Pine Ridge has a total area of 1.3 square miles [3.4 km²].
DeKalb County has a land area of 777 square miles [2,012.7 km²]. At 1.3 square miles [3.4 km²], Pine Ridge has 0.17% 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° 26' 45" (or 34.45°)
Lon: -85° 46' 44" (or -85.78°)

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 Pine Ridge. 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.
