Census Data for Dillingham ...
The most recent Census Estimate<1> was for 2017 and it gave Dillingham a population of 2,360 people.
The last Decennial Census<2> was in 2010, which gave Dillingham a population of 2,329 people.
When the Census Bureau conducts a census for a city like Dillingham, 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 Dillingham reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Dillingham 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 Dillingham has a total area of 36.35 square miles [94.1 km²]. Of this total, 33.57 square miles [86.9 km²] is land, with the balance (7.64%) being water (2.78 square miles [7.2 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: 59° 3' 17" (or 59.1°) [Map]

Population Density ...
Using the population (2,329 people) and land area (33.57 square miles [86.9 km²]) values from the 2010 Census, Dillingham had a population density of 64.1 people per square mile [24.74 people/km²].
In comparison, the 2000 Census shows Dillingham had a population of 2,466 people and a land area of 33.62 square miles [87.1 km²]. This gives a population density of 69 people per square mile [26.64 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 Dillingham. 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 changes can be found in the section Census-to-Census Observations ... (see below).
Housing Units ...
At the time of the 2010 Census, Dillingham had 1,047 Housing Units<3> and with its population of 2,329 people, this averages 2.22 people per Housing Unit.
The 2010 Census shows Dillingham had a land area of 33.57 square miles [86.9 km²]. This translates to 28.8 Housing Units per square mile [11.12 housing units/km²].
From the Census of 2000: Dillingham had 1,000 Housing Units, a population of 2,466 people and a land area of 33.62 square miles [87.1 km²]. This gives a density of 2.47 people per Housing Unit and 27.98 Housing Units per square mile [10.8 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 Dillingham and you need to be careful when comparing values 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).

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 Dillingham. 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.
The sampling area (or polygon) given for the 2010 Census is 1.71% larger than the 2000 Census.

It's important to remember that the boundaries of a ZIP Code can be changed, re-assigned 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.
