Area ...

When the Census Bureau conducts a census for a city like Larsen Bay, they draw a boundary around the area in which they are going to conduct their count - this is called a sampling area (or 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 the population, area and housing for Larsen Bay reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Larsen Bay might be slightly different, it's best to check with the U.S. Census Bureau if you need precision.

The 2010 Census shows that the sample polygon for Larsen Bay has a total area of 7.6 square miles [19.7 km²]. Of this total, 5.39 square miles [14 km²] is land, with the balance (29.05%) being water (2.21 square miles [5.7 km²]).

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 at the center of the polygon). At the time of the 2010 Census, the sampling area was located at:

Lat:   57° 33' 3"   (or 57.6°)             [Map]

Lon:   -154° 0' 17"   (or -154°)

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).

Population Density ...

Using the population (87 people) and land area (5.39 square miles [14 km²]) values from the 2010 Census, Larsen Bay had a population density of 11.45 people per square mile [4.42 people/km²].

In comparison, the 2000 Census shows Larsen Bay had a population of 115 people and a land area of 5.44 square miles [14.1 km²]. This gives a population density of 15.08 people per square mile [5.82 people/km²]

NOTE: Be aware that when comparing population density between the 2000 and the 2010 Census, there were changes in the sampling area for Larsen Bay. You need to be careful when making such a comparison, the differences are likely to lead to a misleading comparison. More information about the changes can be found in the section Census-to-Census Observations ... (see below).

Housing Units ...

The 2010 Census shows Larsen Bay had a land area of 5.39 square miles [14 km²]. This translates to 9.21 Housing Units per square mile [3.56 housing units/km²].

Census-to-Census Observations ...

Introduction ...

When the Census Bureau takes a census count (or enumeration) for Larsen Bay, 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 Larsen Bay. It's important to note that from one Census to the next, the shape and location of the polygon can change. If you need precision or details about the methodology of the Census, you should visit the U.S. Census Bureau for a definitive answer.

Area ...

There is only a very minor difference in the sampling area given between the 2010 Census and the 2000 Census.

The 2010 Census shows that the total area for Larsen Bay was 7.6 square miles [19.7 km²]. Of this total, 5.39 square miles [14 km²] is land, with the balance (29.05%) being water (2.21 square miles [5.7 km²]).

The 2000 Census shows a total area of 7.63 square miles [19.8 km²]. Of this total, 5.44 square miles [14.1 km²] is land, with the balance (28.77%) being water (2.19 square miles [5.7 km²]).

Location ...

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

For the 2010 Census, the location was given as:

Lat:   57.550964°   (or 57°33'3" N)             [Map]

Lon:   -154.004902°   (or -154°0'17" W)

For the 2000 Census, the location given was:

Lat:   57.536651°   (or 57°32'11" N)             [Map]

Lon:   -153.991440°   (or -153°59'29" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 5,845 feet to the northwest<4> 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 (#2419421) to Larsen Bay. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Larsen Bay. The GNIS point has been mapped to the latitude/longitude:

Lat:   57.539731°   (or 57°32'23" N)             [Map]

Lon:   -154.008330°   (or -154°0'29" W)

The GNIS Codes ...

The current system of identification is called the Geographic Names Information System (GNIS). The following GNIS codes relate to Larsen Bay:

GNIS ID for Larsen Bay: 2419421

The US Postal Service ZIP Code ...

While some people have used a ZIP code to identify a community, the purpose of the ZIP code was to make mail delivery more efficient by grouping addresses together. Although the ZIP Code doesn't specifically identify a city like Larsen Bay, it does identify addresses that are in (or near) Larsen Bay. It's important to remember that the boundaries of a ZIP Code can be changed, re-assigned or overlapped with other ZIP Codes.

The ZIP code for Larsen Bay: 99624<6>

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.
