Census Data for Wasilla ...

Population ...

The most recent Census Estimate<1> was for 2016 and it gives Wasilla a population of 9,748 people.

The last Decennial Census<2> was in 2010, giving Wasilla a population of 7,831 people.

The 2010 Census gave Alaska had a population of 710,231 people, meaning that Wasilla had 1.1% of the total population of Alaska - making it the state's 6th most populous community.

Area ...

When the Census Bureau conducts a census for a city like Wasilla, 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 Wasilla reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Wasilla 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 Wasilla has a total area of 13.08 square miles [33.9 km²]. Of this total, 12.38 square miles [32.1 km²] is land, with the balance (5.31%) being water (0.69 square miles [1.8 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:   61° 34' 30"   (or 61.6°)             [Map]

Lon:   -149° 27' 24"   (or -149.46°)

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 (7,831 people) and land area (12.38 square miles [32.1 km²]) values from the 2010 Census, Wasilla had a population density of 598 people per square mile [231.2 people/km²].

In comparison, the 2000 Census shows Wasilla had a population of 5,469 people and a land area of 11.72 square miles [30.3 km²]. This gives a population density of 440.3 people per square mile [170 people/km²]

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

Housing Units ...

At the time of the 2010 Census, Wasilla had 3,277 Housing Units<3> and with its population of 7,831 people, this averages 2.39 people per Housing Unit.

The 2010 Census shows Wasilla had a land area of 12.38 square miles [32.1 km²]. This translates to 250.6 Housing Units per square mile [96.8 housing units/km²].

From the Census of 2000: Wasilla had 2,119 Housing Units, a population of 5,469 people and a land area of 11.72 square miles [30.3 km²]. This gives a density of 2.58 people per Housing Unit and 170.6 Housing Units per square mile [65.9 housing units/km²].

NOTE: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2000 Census and the 2010 Census, there were changes in the sampling area for Wasilla 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 Wasilla, 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 Wasilla. 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 ...

The sampling area (or polygon) given for the 2010 Census is 5.29% larger than the 2000 Census.

The 2010 Census shows that the total area for Wasilla was 13.08 square miles [33.9 km²]. Of this total, 12.38 square miles [32.1 km²] is land, with the balance (5.31%) being water (0.69 square miles [1.8 km²]).

The 2000 Census shows a total area of 12.42 square miles [32.2 km²]. Of this total, 11.72 square miles [30.3 km²] is land, with the balance (5.39%) being water (0.7 square miles [1.8 km²]).

Location ...

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

For the 2010 Census, the location was given as:

Lat:   61.575240°   (or 61°34'30" N)             [Map]

Lon:   -149.456840°   (or -149°27'24" W)

For the 2000 Census, the location given was:

Lat:   61.581732°   (or 61°34'54" N)             [Map]

Lon:   -149.452539°   (or -149°27'9" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 2,481 feet to the south<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 (#2418871) to Wasilla. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Wasilla. The GNIS point has been mapped to the latitude/longitude:

Lat:   61.576903°   (or 61°34'36" N)             [Map]

Lon:   -149.465620°   (or -149°27'56" W)

The GSP location given for the 2010 Census lies 1,639 feet to the east<6> of the point given by the GNIS for Wasilla. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Wasilla.

Miscellaneous Information for Wasilla ...

The GNIS Codes ...

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

GNIS ID for Wasilla: 2418871

US Postal Service ZIP Codes ...

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 Wasilla, 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.

<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>The communities in our count are those provided by the 2010 Census, so keep in mind that our population rings will only include the people living in those communities. Smaller communities usually don't participate directly in the Census and therefore they won't be included. While our count is a close approximation, it shouldn't be considered as a complete or accurate count.
