When the Census Bureau conducts a census for a town like Farmington, 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 town.
Things like the population, area and housing for Farmington reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Farmington 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 Farmington has a total area of 0.43 square miles [1.1 km²]. Of this total, 0.41 square miles [1.1 km²] is land, with the balance (2.58%) being water (0.01 square miles [0 km²]).
Marion County has a land area of 308.7 square miles [799.6 km²]. At 0.41 square miles [1.1 km²], Farmington has 0.13% of the county's total land area.

Lat: 39° 30' 44" (or 39.51°) [Map]
