  • When the Census Bureau conducts a census for a community like Hopkinton, 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 community.
  • Things like population, area and housing for Hopkinton reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Hopkinton 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° 28' 44"   (or 41.48°)
  • Lon:   -71° 45' 28"   (or -71.76°)

  • The 2010 Census shows Hopkinton had a land area of 42.95 square miles [111.2 km²]. This translates to 78.1 Housing Units per square mile [30.17 housing units/km²].
  • From the Census of 2000: Hopkinton had 3,112 Housing Units, a population of 7,836 people and a land area of 42.99 square miles [111.3 km²]. This gives a density of 2.52 people per Housing Unit and 70.5 Housing Units per square mile [27.23 housing units/km²].
  • Note: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2010 Census and the 2000 Census, there were changes in the sampling area for Hopkinton and you need to be careful when comparing values between the censuses. More information about the changes can be found in the section called Census-to-Census Observations ... (see below).

Census-to-Census Observations ...

Introduction ...

When the Census Bureau takes a census count (or enumeration) for Hopkinton, 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 Hopkinton. 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 Hopkinton 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.
  • If you need precision or details about the methodology of the Census, you should visit the U.S. Census Bureau for a definitive answer.
