Area ...

When the Census Bureau conducts a census for a community like Spring Valley, 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 community.

Things like the population, area and housing for Spring Valley reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Spring Valley 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 Spring Valley has a total area of 34.84 square miles [90.2 km²]. Of this total, a small amount of the area is covered by water (0.03 square miles [0.1 km²]).

Rock County has a land area of 718 square miles [1,860 km²]. At 34.82 square miles [90.2 km²], Spring Valley has 4.85% 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:   42° 37' 30"   (or 42.63°)             [Map]

Lon:   -89° 18' 32"   (or -89.31°)

Population Density ...

Using the population (746 people) and land area (34.82 square miles [90.2 km²]) values from the 2010 Census, Spring Valley had a population density of 21.41 people per square mile [8.27 people/km²].

In comparison, the 2000 Census shows Spring Valley had a population of 813 people and a land area of 35.11 square miles [90.9 km²]. This gives a population density of 23.16 people per square mile [8.94 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 Spring Valley. You need to be careful when making such a comparison, the differences are likely to lead to a misleading 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, Spring Valley had 313 Housing Units<3> and with its population of 746 people, this averages 2.38 people per Housing Unit.

The 2010 Census shows Spring Valley had a land area of 34.82 square miles [90.2 km²]. This translates to 8.98 Housing Units per square mile [3.47 housing units/km²].

From the Census of 2000: Spring Valley had 291 Housing Units, a population of 813 people and a land area of 35.11 square miles [90.9 km²]. This gives a density of 2.79 people per Housing Unit and 8.29 Housing Units per square mile [3.2 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 Spring Valley and you need to be careful when comparing results 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 Spring Valley, 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 Spring Valley. 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 0.75% smaller than the 2000 Census.

The 2010 Census shows that the total area for Spring Valley was 34.84 square miles [90.2 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 35.11 square miles [90.9 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 Spring Valley, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Spring Valley.

For the 2010 Census, the location was given as:

Lat:   42.625110°   (or 42°37'30" N)             [Map]

Lon:   -89.309075°   (or -89°18'32" W)

For the 2000 Census, the location given was:

Lat:   42.630205°   (or 42°37'48" N)             [Map]

Lon:   -89.306371°   (or -89°18'22" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 1,994 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 (#1584204) to Spring Valley. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Spring Valley. The GNIS point has been mapped to the latitude/longitude:

Lat:   42.629453°   (or 42°37'46" N)             [Map]

Lon:   -89.314005°   (or -89°18'50" W)

The GSP location given for the 2010 Census lies 2,063 feet to the southeast<6> of the point given by the GNIS for Spring Valley. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Spring Valley.

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 158 degrees and a distance of 1,994 feet.
<6>The calculated bearing (or angle) to the GNIS point is 219 degrees and a distance of 2,063 feet.
