- When the Census Bureau conducts a census for a city like Cortland, they draw a boundary around the area in which they are going to conduct their count - this defines the sampling area (usually 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 population, area and housing for Cortland reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Cortland 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: 41° 19' 54" (or 41.33°)
- Lon: -80° 43' 9" (or -80.72°)

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 Cortland. It's important to note that from one Census to the next, the shape and location of the polygon can change.

- Although we don't have specific information about the shape of the polygon for Cortland or how it changed has over time, there is some information that can give us some hints. For example, since the shape of the sampling area is directly related to the shape of the polygon, any change to area probably indicates a new shape for the polygon.
