    • When the Census Bureau conducts a census for a community like Hamden, 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 Hamden reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Hamden 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° 23' 50"   (or 41.4°)
    • Lon:   -72° 55' 19"   (or -72.92°)
    • 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, Hamden had 25,114 Housing Units<3> and with its population of 60,960 people, this averages 2.43 people per Housing Unit.

  • Continue Reading ...
    • The 2010 Census shows Hamden had a land area of 32.65 square miles [84.6 km²]. This translates to 753 Housing Units per square mile [291.1 housing units/km²].
    • From the Census of 2000: Hamden had 23,464 Housing Units, a population of 56,913 people and a land area of 32.78 square miles [84.9 km²]. This gives a density of 2.43 people per Housing Unit and 704 Housing Units per square mile [271.9 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 Hamden and you need to be careful when comparing values between the censuses. More information about these differences 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 Hamden, 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 Hamden. It's important to note that from one Census to the next, the shape and location of the polygon can change.

  • Continue Reading ...
    • Although we don't have specific information about the shape of the polygon for Hamden 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 Hamden, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Hamden.

    • For the 2000 Census, the location given was:
    • Lat:   41.370447°   (or 41°22'13" N)
    • Lon:   -72.921388°   (or -72°55'16" W)
    • The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 9,815 feet to the north<5> of the location that was used in the 2000 Census.

    • Lat:   41.397875°   (or 41°23'52" N)
    • Lon:   -72.921769°   (or -72°55'18" W)

Footnotes ...

<1>Every year, the US Census Bureau creates a population estimate for the preceeding year. Keep in mind that this value is an estimate and not an actual count. The most recent Census estimate is for the year 2019.
<2>Every 10 years (eg- 1990, 2000, 2010), the US Census Bureau conducts a Constitutionally-mandated count (or enumeration) of people living within the United States. This count is called a Decennial Census. The last Decennial Census was the 2010 Census, with the next one planned for 2020.
<3>A Housing Unit is a broad term for those places where people live (whether occupied or temporarily vacant), such as a house, an apartment, a mobile home, or an area that is considered as a separate living quarter. Separate living quarters (consisting of one or more rooms) are considered to be those places where people live, sleep and eat separately from others and that have access to the outside (either directly or by a shared hallway).
<4>If you're interested in how the shape of Connecticut's counties, including New Haven, have changed over time, we recommend the Atlas of Historical County Boundaries.
<5>The calculated bearing (or angle) to the 2010 Census location is 1 degrees and a distance of 9,815 feet.
<6>The calculated bearing (or angle) to the GNIS point is 147 degrees and a distance of 222.5 feet.
