When the Census Bureau conducts a census for a city like Owasa, they draw a boundary around the area in which they are going to conduct their count - this defines the sampling area (usually shaped as 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 city.
Things like the population, area and housing for Owasa reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Owasa might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.

Lat: 42° 25' 54" (or 42.43°) [Map]
