Area ...

When the Census Bureau conducts a census for a town like Altoona, 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 Altoona reflect the sampling area. Since the shape of the sampling area and the actual boundaries of&$160;Altoona 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 Altoona has a total area of 4.33 square miles [11.2 km²]. Of this total, a small amount of the area is covered by water (0.01 square miles [0 km²]).

Etowah County has a land area of 534 square miles [1,385.6 km²]. At 4.32 square miles [11.2 km²], Altoona has 0.81% 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° 1' 45"   (or 34.03°)

Lon:   -86° 19' 14"   (or -86.32°)

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 (933 people) and land area (4.32 square miles [11.2 km²]) values from the 2010 Census, Altoona had a population density of 215.6 people per square mile [83.2 people/km²].

In comparison, the 2000 Census shows Altoona had a population of 984 people and a land area of 3.8 square miles [9.9 km²]. This gives a population density of 258 people per square mile [99.6 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 Altoona. You need to be careful when making such a comparison, the differences are likely to lead to a misleading 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, Altoona had 426 Housing Units<3> and with its population of 933 people, this averages 2.19 people per Housing Unit.

The 2010 Census shows Altoona had a land area of 4.32 square miles [11.2 km²]. This translates to 98.4 Housing Units per square mile [38 housing units/km²].

From the Census of 2000: Altoona had 437 Housing Units, a population of 984 people and a land area of 3.8 square miles [9.9 km²]. This gives a density of 2.25 people per Housing Unit and 114.6 Housing Units per square mile [44.23 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 Altoona and you need to be careful when comparing results 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 Altoona, 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 Altoona. 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 13.46% larger than the 2000 Census.

The 2010 Census shows that the total area for Altoona was 4.33 square miles [11.2 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 3.81 square miles [9.9 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 Altoona, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Altoona.

For the 2010 Census, the location was given as:

Lat:   34.039218°   (or 34°2'21" N)

Lon:   -86.305671°   (or -86°18'20" W)

For the 2000 Census, the location given was:

Lat:   34.029259°   (or 34°1'45" N)

Lon:   -86.320687°   (or -86°19'14" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 5,810 feet to the northeast<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 (#2405146) to Altoona. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Altoona. The GNIS point has been mapped to the latitude/longitude:

Lat:   34.033074°   (or 34°1'59" N)

Lon:   -86.313625°   (or -86°18'49" W)

The GSP location given for the 2010 Census lies 3,285 feet to the northeast<6> of the point given by the GNIS for Altoona. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Altoona.

Miscellaneous Information for Altoona ...

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 Etowah County or the town of Altoona:

The GNIS Codes ...

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

GNIS ID for Altoona: 2405146

GNIS ID for Etowah County: 161553

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: 055 (Etowah County)

Place Code: 01660 (Altoona)

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

State & Place Code: 01/01660 (Alabama / Altoona)

Misc. Census Codes ...

Altoona 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 Altoona, it does identify addresses that are in (or near) Altoona. 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 Altoona: 35952<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).

<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.
