Area ...

When the Census Bureau conducts a census for a village like Star Prairie, 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 village.

Things like the population, area and housing for Star Prairie reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Star Prairie 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 Star Prairie has a total area of 2.16 square miles [5.6 km²].

Saint Croix County has a land area of 722 square miles [1,870.8 km²]. At 2.16 square miles [5.6 km²], Star Prairie has 0.3% 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' 51"   (or 45.2°)             [Map]

Lon:   -92° 31' 55"   (or -92.53°)

Population Density ...

Using the population (561 people) and land area (2.16 square miles [5.6 km²]) values from the 2010 Census, Star Prairie had a population density of 259.7 people per square mile [100.3 people/km²].

In comparison, the 2000 Census shows Star Prairie had a population of 574 people and a land area of 2.1 square miles [5.4 km²]. This gives a population density of 273.3 people per square mile [105.5 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 Star Prairie. You need to be careful when making such a comparison, the differences are likely to lead to a questionable comparison. More information about the changes can be found in the section Census-to-Census Observations ... (see below).

Housing Units ...

At the time of the 2010 Census, Star Prairie had 248 Housing Units<3> and with its population of 561 people, this averages 2.26 people per Housing Unit.

The 2010 Census shows Star Prairie had a land area of 2.16 square miles [5.6 km²]. This translates to 114.8 Housing Units per square mile [44.33 housing units/km²].

From the Census of 2000: Star Prairie had 215 Housing Units, a population of 574 people and a land area of 2.1 square miles [5.4 km²]. This gives a density of 2.67 people per Housing Unit and 102.4 Housing Units per square mile [39.53 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 Star Prairie 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 Star Prairie, 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 Star Prairie. 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 2.85% larger than the 2000 Census.

The 2010 Census shows that the total area for Star Prairie was 2.16 square miles [5.6 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 2.1 square miles [5.4 km²]. Of this total, only a minor amount of the area is covered by water.

Location ...

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

For the 2010 Census, the location was given as:

Lat:   45.197511°   (or 45°11'51" N)             [Map]

Lon:   -92.532078°   (or -92°31'55" W)

For the 2000 Census, the location given was:

Lat:   45.198274°   (or 45°11'53" N)             [Map]

Lon:   -92.531987°   (or -92°31'55" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 279.2 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 (#1584214) to Star Prairie. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Star Prairie. The GNIS point has been mapped to the latitude/longitude:

Lat:   45.198298°   (or 45°11'53" N)             [Map]

Lon:   -92.531865°   (or -92°31'54" W)

The GSP location given for the 2010 Census lies 292.1 feet to the south<6> of the point given by the GNIS for Star Prairie. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Star Prairie.

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 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.
<5>The calculated bearing (or angle) to the 2010 Census location is 175 degrees and a distance of 279.2 feet.
<6>The calculated bearing (or angle) to the GNIS point is 169 degrees and a distance of 292.1 feet.
