When the Census Bureau conducts a census for a town like Hobson City, 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 Hobson City reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Hobson City might be slightly different, it's best to check with the U.S. Census Bureau if you need precision.

Lat: 33° 37' 7" (or 33.62°) [Map]
Lon: -85° 50' 46" (or -85.85°)
