Area ...

When the Census Bureau conducts a census for a town like Union Grove, they draw a boundary around the area in which they are going to conduct their count - this is called a sampling area (or 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 town.

Things like the population, area and housing for Union Grove reflect the sampling area. Since the shape of the sampling area and the actual boundaries of&$160;Union Grove might be slightly different, it's best to check with the U.S. Census Bureau if you need precision.

The 2010 Census shows that the sample polygon for Union Grove has a total area of 0.57 square miles [1.5 km²]. Of this total, 0.56 square miles [1.4 km²] is land, with the balance (1.77%) being water (0.01 square miles [0 km²]).

Marshall County has a land area of 565 square miles [1,465.5 km²]. At 0.56 square miles [1.4 km²], Union Grove has 0.1% 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 at the center of the polygon). At the time of the 2010 Census, the sampling area was located at:

Lat:   34° 24' 0"   (or 34.4°)

Lon:   -86° 26' 45"   (or -86.45°)

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 (77 people) and land area (0.56 square miles [1.4 km²]) values from the 2010 Census, Union Grove had a population density of 136 people per square mile [52.5 people/km²].

In comparison, the 2000 Census shows Union Grove had a population of 94 people and a land area of 0.57 square miles [1.5 km²]. This gives a population density of 164.4 people per square mile [63.5 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 Union Grove. 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 differences can be found in the section Census-to-Census Observations ... (see below).

Housing Units ...

At the time of the 2010 Census, Union Grove had 39 Housing Units<3> and with its population of 77 people, this averages 1.97 people per Housing Unit.

The 2010 Census shows Union Grove had a land area of 0.56 square miles [1.4 km²]. This translates to 68.9 Housing Units per square mile [26.6 housing units/km²].

From the Census of 2000: Union Grove had 41 Housing Units, a population of 94 people and a land area of 0.57 square miles [1.5 km²]. This gives a density of 2.29 people per Housing Unit and 71.7 Housing Units per square mile [27.68 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 Union Grove and you need to be careful when comparing 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 Union Grove, 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 Union Grove. 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 1.04% smaller than the 2000 Census.

The 2010 Census shows that the total area for Union Grove was 0.57 square miles [1.5 km²]. Of this total, 0.56 square miles [1.4 km²] is land, with the balance (1.77%) being water (0.01 square miles [0 km²]).

The 2000 Census shows a total area of 0.57 square miles [1.5 km²]. Of this total, 0.57 square miles [1.5 km²] is land, with the balance (0.69%) being water (0 square miles [0 km²]).

Location ...

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

For the 2010 Census, the location was given as:

Lat:   34.406172°   (or 34°24'22" N)

Lon:   -86.451667°   (or -86°27'6" W)

For the 2000 Census, the location given was:

Lat:   34.400088°   (or 34°24'0" N)

Lon:   -86.446049°   (or -86°26'45" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 2,788 feet to the northwest<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 (#2406778) to Union Grove. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Union Grove. The GNIS point has been mapped to the latitude/longitude:

Lat:   34.402560°   (or 34°24'9" N)

Lon:   -86.448322°   (or -86°26'53" W)

The GSP location given for the 2010 Census lies 1,657 feet to the northwest<6> of the point given by the GNIS for Union Grove. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Union Grove.

Miscellaneous Information for Union Grove ...

The Federal government has assigned various identifying codes to each community, county and state. At one time or another, the US Census Bureau has referenced one (or more) of the following identifiers when referring to either Marshall County or the town of Union Grove:

The GNIS Codes ...

The current system of identification is called the Geographic Names Information System (GNIS). The following GNIS codes relate to Union Grove:

GNIS ID for Union Grove: 2406778

GNIS ID for Marshall County: 161574

GNIS ID for Alabama: 1779775

The FIPS Codes ...

An earlier (and largely obsolete) identification method was called the Federal Information Processing Standard (FIPS):

State Code: 01 (Alabama)

County Code: 095 (Marshall County)

Place Code: 77784 (Union Grove)

State & County Code: 01/095 (Alabama / Marshall County)

State & Place Code: 01/77784 (Alabama / Union Grove)

Misc. Census Codes ...

Union Grove is located in Census Region #3 (the South Region) and Division #6 (the East South-Central Division).

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 town like Union Grove, it does identify addresses that are in (or near) Union Grove. It's important to remember that the boundaries of a ZIP Code can be changed, re-assigned or overlapped with other ZIP Codes.

The ZIP code for Union Grove: 35175<7>

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.

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 2015.

- Return to Citation

<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.

- Return to Citation

<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).

- Return to Citation

<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.
