Area ...

When the Census Bureau conducts a census for a city like Marine-on-Saint-Croix, 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 Marine-on-Saint-Croix reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Marine-on-Saint-Croix 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 Marine-on-Saint-Croix has a total area of 4.17 square miles [10.8 km²]. Of this total, 3.88 square miles [10.1 km²] is land, with the balance (7%) being water (0.29 square miles [0.8 km²]).

Washington County has a land area of 384.3 square miles [995.3 km²]. At 3.88 square miles [10.1 km²], Marine-on-Saint-Croix has 1.01% of the county's total land area.

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:   45° 11' 27"   (or 45.19°)             [Map]

Lon:   -92° 46' 42"   (or -92.78°)

Census-to-Census Observations ...

Introduction ...

When the Census Bureau takes a census count (or enumeration) for Marine-on-Saint-Croix, 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 Marine-on-Saint-Croix. 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 2000 Census shows a total area of 4.17 square miles [10.8 km²]. Of this total, 3.94 square miles [10.2 km²] is land, with the balance (5.55%) being water (0.23 square miles [0.6 km²]).

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 Marine-on-Saint-Croix, it does identify addresses that are in (or near) Marine-on-Saint-Croix. 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.

<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).
