When the Census Bureau conducts a census for a city like Grafton, 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 city.
Things like the population, area and housing for Grafton reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Grafton might be slightly different, it's best to check with the U.S. Census Bureau if you need precision.
The 2010 Census shows that the sample polygon for Grafton has a total area of 3.4 square miles [8.8 km²].
Walsh County has a land area of 1,281 square miles [3,320.2 km²]. At 3.4 square miles [8.8 km²], Grafton has 0.26% 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 at the center of the polygon). At the time of the 2010 Census, the sampling area was located at:
Lat: 48° 24' 52" (or 48.41°) [Map]
Lon: -97° 24' 22" (or -97.41°)

NOTE: Be aware that when comparing population density between the 2000 and the 2010 Census, there were changes in the sampling area for Grafton. You need to be careful when making such a comparison, the differences are likely to lead to an apple-to-oranges comparison. More information about these differences can be found in the section Census-to-Census Observations ... (see below).

When the Census Bureau takes a census count (or enumeration) for Grafton, they start by specifying the boundaries of the area to be counted. This area (or sampling area) is a polygon and its shape can be quite complex - it may or may not match the geographical boundaries of Grafton. It's important to note that from one Census to the next, the shape and location of the polygon can change.
If you need precision or details about the methodology of the Census, you should visit the U.S. Census Bureau for a definitive answer.
