  • When the Census Bureau conducts a census for a community like Bridgewater, 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 Bridgewater reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Bridgewater 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:   43° 40' 5"   (or 43.67°)
  • Lon:   -71° 41' 14"   (or -71.69°)

  • The 2010 Census shows Bridgewater had a land area of 21.23 square miles [55 km²]. This translates to 46.43 Housing Units per square mile [17.93 housing units/km²].
  • From the Census of 2000: Bridgewater had 850 Housing Units, a population of 974 people and a land area of 21.27 square miles [55.1 km²]. This gives a density of 1.15 people per Housing Unit and 39.62 Housing Units per square mile [15.3 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 Bridgewater 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 Bridgewater, 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 Bridgewater. 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 Bridgewater 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.

Location ...

While generally coinciding with the GPS location (latitude/longitude) of Bridgewater, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Bridgewater.

  • For the 2010 Census, the location was given as:
  • Lat:   43.668259°   (or 43°40'5" N)

  • Lon:   -71.720392°   (or -71°43'13" W)
  • The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 8,824 feet to the east<5> of the location that was used in the 2000 Census.
  • The U.S. Geological Survey (USGS) and the U.S. Board on Geographic Names (BGN) have assigned a unique GNIS identifier (#873551) to Bridgewater. This identifier also marks a GPS point on the map, and that point lies within the boundaries of Bridgewater. The GNIS point has been mapped to the latitude/longitude:
