  • When the Census Bureau conducts a census for a community like Cromwell, 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 Cromwell reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Cromwell 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° 36' 59"   (or 41.62°)
  • Lon:   -72° 39' 41"   (or -72.66°)
  • More information on this topic and the changes between the 2000 Census and the 2010 Census can be found in the section for our Census-to-Census Observations ... (see below).

Housing Units ...

At the time of the 2010 Census, Cromwell had 6,001 Housing Units<3> and with its population of 14,005 people, this averages 2.33 people per Housing Unit.

  • The 2010 Census shows Cromwell had a land area of 12.45 square miles [32.3 km²]. This translates to 463.4 Housing Units per square mile [178.9 housing units/km²].
  • From the Census of 2000: Cromwell had 5,365 Housing Units, a population of 12,871 people and a land area of 12.39 square miles [32.1 km²]. This gives a density of 2.4 people per Housing Unit and 415.6 Housing Units per square mile [160.5 housing units/km²].
  • Note: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2010 and the 2000 Census, there were changes in the sampling area for Cromwell and you need to be careful when comparing numbers 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 Cromwell, 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 Cromwell. 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 Cromwell 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 Cromwell, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Cromwell.

  • The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 2,926 feet to the northeast<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 (#213414) to Cromwell.
