When the Census Bureau conducts a census for a community like Willow, 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 community.
Things like the population, area and housing for Willow reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Willow might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.

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 the center of the polygon, known as the centroid). At the time of the 2010 Census, the sampling area was located at:
Lat: 43° 25' 0" (or 43.42°) [Map]
