Area ...

When the Census Bureau conducts a census for a town like Sardis City, 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 Sardis City reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Sardis City 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 Sardis City has a total area of 7.87 square miles [20.4 km²]. Of this total, a small amount of the area is covered by water (0.02 square miles [0 km²]).

Etowah County has a land area of 534 square miles [1,385.6 km²]. At 7.85 square miles [20.3 km²], Sardis City has 1.47% 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° 10' 20"   (or 34.17°)             [Map]

Lon:   -86° 7' 8"   (or -86.12°)

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 (1,704 people) and land area (7.85 square miles [20.3 km²]) values from the 2010 Census, Sardis City had a population density of 216.6 people per square mile [83.6 people/km²].

In comparison, the 2000 Census shows Sardis City had a population of 1,438 people and a land area of 7.37 square miles [19.1 km²]. This gives a population density of 194.7 people per square mile [75.2 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 Sardis City. 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, Sardis City had 703 Housing Units<3> and with its population of 1,704 people, this averages 2.42 people per Housing Unit.

The 2010 Census shows Sardis City had a land area of 7.85 square miles [20.3 km²]. This translates to 89.3 Housing Units per square mile [34.5 housing units/km²].

From the Census of 2000: Sardis City had 597 Housing Units, a population of 1,438 people and a land area of 7.37 square miles [19.1 km²]. This gives a density of 2.41 people per Housing Unit and 80.8 Housing Units per square mile [31.2 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 Sardis City and you need to be careful when comparing between the censuses. More information about 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 Sardis City, 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 Sardis City. 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 6.51% larger than the 2000 Census.

The 2010 Census shows that the total area for Sardis City was 7.87 square miles [20.4 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 7.39 square miles [19.1 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 Sardis City, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Sardis City.

For the 2010 Census, the location was given as:

Lat:   34.172413°   (or 34°10'20" N)             [Map]

Lon:   -86.119104°   (or -86°7'8" W)

For the 2000 Census, the location given was:

Lat:   34.173967°   (or 34°10'26" N)             [Map]

Lon:   -86.121319°   (or -86°7'16" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 876 feet to the southeast<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 (#2407291) to Sardis City. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Sardis City. The GNIS point has been mapped to the latitude/longitude:

Lat:   34.175353°   (or 34°10'31" N)             [Map]

Lon:   -86.114699°   (or -86°6'52" W)

The GSP location given for the 2010 Census lies 1,707 feet to the southwest<6> of the point given by the GNIS for Sardis City. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Sardis City.

The GNIS Codes ...

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

GNIS ID for Sardis City: 2407291

GNIS ID for Etowah County: 161553

GNIS ID for Alabama: 1779775

County Code: 055 (Etowah County)

Place Code: 68280 (Sardis City)

State & County Code: 01/055 (Alabama / Etowah County)

State & Place Code: 01/68280 (Alabama / Sardis City)

Misc. Census Codes ...

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

US Postal Service ZIP Codes ...

While some people have used ZIP codes to identify a community, the ZIP codes were actually created to make mail delivery more efficient by grouping addresses together. Although a ZIP Code doesn't specifically identify a town like Sardis City, they do identify addresses that are in (or near) the town. It's important to remember that the boundaries of the ZIP Code can be changed, re-assigned, eliminated 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.

<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.
