Census Data for Kotlik ...

Population ...

The most recent Census Estimate<1> was for 2018 and it gave Kotlik a population of 637 people.

The last Decennial Census<2> was in 2010, which gave Kotlik a population of 577 people.

The 2010 Census gave Alaska had a population of 710,231 people, meaning that Kotlik had 0.08% of the total population of Alaska - making it the state's 48th most populous community.

Area ...

When the Census Bureau conducts a census for a city like Kotlik, they draw a boundary around the area in which they are going to conduct their count - this defines the sampling area (usually shaped as 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 Kotlik reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Kotlik might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.

The 2010 Census shows that the sampling area for Kotlik has a total area of 4.5 square miles [11.7 km²]. Of this total, 3.78 square miles [9.8 km²] is land, with the balance (16.1%) being water (0.72 square miles [1.9 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 the center of the polygon, known as the centroid). At the time of the 2010 Census, the sampling area was located at:

Lat:   63° 1' 43"   (or 63°)             [Map]

Lon:   -163° 32' 8"   (or -163.54°)

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 (577 people) and land area (3.78 square miles [9.8 km²]) values from the 2010 Census, Kotlik had a population density of 128.1 people per square mile [49.47 people/km²].

In comparison, the 2000 Census shows Kotlik had a population of 591 people and a land area of 3.82 square miles [9.9 km²]. This gives a population density of 127 people per square mile [49.05 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 Kotlik. You need to be careful when making such a comparison, the differences are likely to lead to a questionable comparison. More information about the nature of these changes can be found in the section Census-to-Census Observations ... (see below).

Housing Units ...

At the time of the 2010 Census, Kotlik had 148 Housing Units<3> and with its population of 577 people, this averages 3.9 people per Housing Unit.

The 2010 Census shows Kotlik had a land area of 3.78 square miles [9.8 km²]. This translates to 32.87 Housing Units per square mile [12.69 housing units/km²].

From the Census of 2000: Kotlik had 139 Housing Units, a population of 591 people and a land area of 3.82 square miles [9.9 km²]. This gives a density of 4.25 people per Housing Unit and 29.88 Housing Units per square mile [11.54 housing units/km²].

NOTE: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2000 and the 2010 Census, there were changes in the sampling area for Kotlik and you need to be careful when comparing 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 Kotlik, 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 Kotlik. 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 3.21% smaller than the 2000 Census.

The 2010 Census shows that the total area for Kotlik was 4.5 square miles [11.7 km²]. Of this total, 3.78 square miles [9.8 km²] is land, with the balance (16.1%) being water (0.72 square miles [1.9 km²]).

The 2000 Census shows a total area of 4.65 square miles [12 km²]. Of this total, 3.82 square miles [9.9 km²] is land, with the balance (18.5%) being water (0.83 square miles [2.2 km²]).

Location ...

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

For the 2010 Census, the location was given as:

Lat:   63.028875°   (or 63°1'43" N)             [Map]

Lon:   -163.535732°   (or -163°32'8" W)

For the 2000 Census, the location given was:

Lat:   63.035769°   (or 63°2'8" N)             [Map]

Lon:   -163.560177°   (or -163°33'36" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 4,759 feet to the southeast<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 (#2419415) to Kotlik. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Kotlik. The GNIS point has been mapped to the latitude/longitude:

Lat:   63.030657°   (or 63°1'50" N)             [Map]

Lon:   -163.557540°   (or -163°33'27" W)

The GSP location given for the 2010 Census lies 3,663 feet to the east<5> of the point given by the GNIS for Kotlik. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Kotlik.

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 2018.
<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>The calculated bearing (or angle) to the 2010 Census location is 238 degrees and a distance of 4,759 feet.
<5>The calculated bearing (or angle) to the GNIS point is 259 degrees and a distance of 3,663 feet.
