When the Census Bureau conducts a census for a city like Orem, 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 Orem reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Orem might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.
The 2010 Census shows that the sampling area for Orem has a total area of 18.29 square miles [47.4 km²].
Utah County has a land area of 2,003 square miles [5,188.9 km²]. At 18.29 square miles [47.4 km²], Orem has 0.91% 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 the center of the polygon, known as the centroid). At the time of the 2010 Census, the sampling area was located at:
Lat: 40° 17' 55" (or 40.3°) [Map]
