Census Data for Galena ...
The most recent Census Estimate<1> was for 2018 and it gave Galena a population of 469 people.
The last Decennial Census<2> was in 2010, which gave Galena a population of 470 people.
When the Census Bureau conducts a census for a city like Galena, 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 Galena reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Galena 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 Galena has a total area of 24.09 square miles [62.4 km²]. Of this total, 17.73 square miles [45.9 km²] is land, with the balance (26.42%) being water (6.37 square miles [16.5 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: 64° 44' 23" (or 64.7°) [Map]
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 (470 people) and land area (17.73 square miles [45.9 km²]) values from the 2010 Census, Galena had a population density of 19.51 people per square mile [7.53 people/km²].
In comparison, the 2000 Census shows Galena had a population of 675 people and a land area of 17.87 square miles [46.3 km²]. This gives a population density of 28.16 people per square mile [10.87 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 Galena. You need to be careful when making such a comparison, the differences are likely to lead to a misleading 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, Galena had 264 Housing Units<3> and with its population of 470 people, this averages 1.78 people per Housing Unit.
The 2010 Census shows Galena had a land area of 17.73 square miles [45.9 km²]. This translates to 10.96 Housing Units per square mile [4.23 housing units/km²].
From the Census of 2000: Galena had 259 Housing Units, a population of 675 people and a land area of 17.87 square miles [46.3 km²]. This gives a density of 2.61 people per Housing Unit and 10.81 Housing Units per square mile [4.17 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 Galena and you need to be careful when comparing 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 ...
When the Census Bureau takes a census count (or enumeration) for Galena, 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 Galena. 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 0.52% larger than the 2000 Census.
The 2010 Census shows that the total area for Galena was 24.09 square miles [62.4 km²]. Of this total, 17.73 square miles [45.9 km²] is land, with the balance (26.42%) being water (6.37 square miles [16.5 km²]).
The 2000 Census shows a total area of 23.97 square miles [62.1 km²]. Of this total, 17.87 square miles [46.3 km²] is land, with the balance (25.29%) being water (6.09 square miles [15.8 km²]).
While generally coinciding with the GPS location (latitude/longitude) of Galena, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Galena.
For the 2010 Census, the location was given as:
Lat: 64.739952° (or 64°44'23" N) [Map]
For the 2000 Census, the location given was:
Lat: 64.740643° (or 64°44'26" N) [Map]
The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 1,805 feet to the east<5> of the location that was used in the 2000 Census.

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.

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.
