  • When the Census Bureau conducts a census for a city like Middletown, 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 Middletown reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Middletown 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° 32' 58"   (or 41.55°)
  • Lon:   -72° 39' 27"   (or -72.66°)

At the time of the 2010 Census, Middletown had 21,223 Housing Units<3> and with its population of 47,648 people, this averages 2.25 people per Housing Unit.

  • The 2010 Census shows Middletown had a land area of 41.02 square miles [106.2 km²]. This translates to 500 Housing Units per square mile [193.4 housing units/km²].
  • From the Census of 2000: Middletown had 19,697 Housing Units, a population of 43,167 people and a land area of 40.9 square miles [105.9 km²]. This gives a density of 2.19 people per Housing Unit and 465.4 Housing Units per square mile [179.7 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 Middletown and you need to be careful when comparing numbers between the censuses. More information about the nature of these 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 Middletown, 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 Middletown. 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 Middletown 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 Middletown, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Middletown.

  • The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 2,125 feet to the southeast<5> of the location that was used in the 2000 Census.

Miscellaneous Information for Middletown ...

The Federal government has assigned various identifying codes to each community, county and state. At one time or another, the US Census Bureau has used one (or more) of the following identifiers when referring to either Middlesex County or the city of Middletown:

• The GNIS Codes ...
  • The current system of identification is called the Geographic Names Information System (GNIS). The following GNIS codes relate to Middletown:
  • GNIS ID for Middletown: 2378281
  • GNIS ID for Middlesex County: 212797
  • GNIS ID for State of Connecticut: 1779780

• The FIPS Codes ...
  • An earlier (and largely obsolete) identification method was called the Federal Information Processing Standard (FIPS):
  • State Code: 09 (Connecticut)
  • County Code: 007 (Middlesex County)
  • Place Code: 47290 (Middletown)
  • State & County Code: 09/007 (Connecticut / Middlesex County)
  • State & Place Code: 09/47290 (Connecticut / Middletown)

• Misc. Census Codes ...
  • Middletown is located in Census Region #1 (the Northeast Region) and Division #1 (the New England Division).

• The US Postal Service ZIP Code ...
  • While some people have used ZIP codes to identify a community, the ZIP codes were actually created to make mail delivery more efficient by grouping addresses together. Although a ZIP Code doesn't specifically identify a city like Middletown, they do identify addresses that are in (or near) the city. It's important to remember that the boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes.

• Census ZCTA Codes ...
  • The US Census Bureau created statistical entities that they call ZIP Code Tabulation Areas (ZCTAs) and these ZCTAs are frequently confused with the ZIP codes that come from the US Postal Service (USPS).
  • ZCTAs were first created for the 2000 Census and at that time, they were based upon the USPS ZIP codes. While largely covering the same areas, the boundaries of a ZCTA do not necessarily match the boundaries of a postal ZIP code with the same number. For example, while a postal ZIP code can cross a county or state line, a Census ZCTA can not. They should be treated as separate entities with no correlation between them.
