Census Data for Andalusia ...

Population ...

The most recent Census Estimate<1> was for 2016 and it gives Andalusia a population of 8,968 people.

The last Decennial Census<2> was in 2010, giving Andalusia a population of 9,015 people.

The city of Andalusia is located in Covington County. The 2010 Census gave Covington County a population of 37,765 people. This means that Andalusia had 23.87% of the county's total population, making it Covington's most populous community.

At the same time, Alabama had a population of 4,779,736 people, meaning that Andalusia had 0.19% of the total population of Alabama - making it the state's 70th most populous community.

Area ...

When the Census Bureau conducts a census for a city like Andalusia, 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 city.

Things like the population, area and housing for Andalusia reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Andalusia 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 Andalusia has a total area of 19.81 square miles [51.3 km²]. Of this total, a small amount of the area is covered by water (0.16 square miles [0.4 km²]).

Covington County has a land area of 1,030 square miles [2,668.9 km²]. At 19.66 square miles [50.9 km²], Andalusia has 1.91% 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:   31° 18' 33"   (or 31.31°)             [Map]

Lon:   -86° 28' 40"   (or -86.48°)

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 (9,015 people) and land area (19.66 square miles [50.9 km²]) values from the 2010 Census, Andalusia had a population density of 455 people per square mile [175.7 people/km²].

In comparison, the 2000 Census shows Andalusia had a population of 8,794 people and a land area of 18.87 square miles [48.9 km²]. This gives a population density of 463.6 people per square mile [179 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 Andalusia. 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, Andalusia had 4,356 Housing Units<3> and with its population of 9,015 people, this averages 2.07 people per Housing Unit.

The 2010 Census shows Andalusia had a land area of 19.66 square miles [50.9 km²]. This translates to 219.9 Housing Units per square mile [84.9 housing units/km²].

From the Census of 2000: Andalusia had 4,279 Housing Units, a population of 8,794 people and a land area of 18.87 square miles [48.9 km²]. This gives a density of 2.06 people per Housing Unit and 225.6 Housing Units per square mile [87.1 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 Andalusia 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).

Covington County ...

Andalusia is located in Covington County and is the County Seat for Covington County.

The county had a population of 37,765 people at the 2010 Census. With it's population of 9,015 people, Andalusia represented 23.87% of the county's total.

Census-to-Census Observations ...

Introduction ...

When the Census Bureau takes a census count (or enumeration) for Andalusia, 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 Andalusia. 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 4.45% larger than the 2000 Census.

The 2010 Census shows that the total area for Andalusia was 19.81 square miles [51.3 km²]. Of this total, 19.66 square miles [50.9 km²] is land, with the balance (0.79%) being water (0.16 square miles [0.4 km²]).

The 2000 Census shows a total area of 18.97 square miles [49.1 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 Andalusia, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Andalusia.

For the 2010 Census, the location was given as:

Lat:   31.309436°   (or 31°18'33" N)             [Map]

Lon:   -86.478031°   (or -86°28'40" W)

For the 2000 Census, the location given was:

Lat:   31.309321°   (or 31°18'33" N)             [Map]

Lon:   -86.479468°   (or -86°28'46" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 449.6 feet to the east<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 (#2403097) to Andalusia. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Andalusia. The GNIS point has been mapped to the latitude/longitude:

Lat:   31.309621°   (or 31°18'34" N)             [Map]

Lon:   -86.479631°   (or -86°28'46" W)

The GSP location given for the 2010 Census lies 502 feet to the east<6> of the point given by the GNIS for Andalusia. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Andalusia.

Miscellaneous Information for Andalusia ...

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 Covington County or the city of Andalusia:

The GNIS Codes ...

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

GNIS ID for Andalusia: 2403097

GNIS ID for Covington County: 161545

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: 039 (Covington County)

Place Code: 01708 (Andalusia)

State & County Code: 01/039 (Alabama / Covington County)

State & Place Code: 01/01708 (Alabama / Andalusia)

Misc. Census Codes ...

Andalusia 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 city like Andalusia, it does identify addresses that are in (or near) Andalusia. 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 Andalusia: 36420<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.

<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.
