Census Data for Tuscaloosa ...

Population ...

The most recent Census Estimate<1> was for 2015 and it gives Tuscaloosa a population of 98,332 people.

The last Decennial Census<2> was in 2010, giving Tuscaloosa a population of 90,468 people.

The city of Tuscaloosa is located in Tuscaloosa County. The 2010 Census gave Tuscaloosa County a population of 194,656 people. This means that Tuscaloosa had 46.48% of the county's total population, making it Tuscaloosa's most populous community.

At the same time, Alabama had a population of 4,779,736 people, meaning that Tuscaloosa had 1.89% of the total population of Alabama - making it the state's 5th most populous community.

Area ...

When the Census Bureau conducts a census for a city like Tuscaloosa, 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 Tuscaloosa reflect the sampling area. Since the shape of the sampling area and the actual boundaries of&$160;Tuscaloosa 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 Tuscaloosa has a total area of 70.4 square miles [182.2 km²]. Of this total, 60.2 square miles [156 km²] is land, with the balance (14.38%) being water (10.12 square miles [26.2 km²]).

Tuscaloosa County has a land area of 1,321 square miles [3,423.3 km²]. At 60.2 square miles [156 km²], Tuscaloosa has 4.56% 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:   33° 12' 23"   (or 33.21°)

Lon:   -87° 32' 4"   (or -87.53°)

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 (90,468 people) and land area (60.2 square miles [156 km²]) values from the 2010 Census, Tuscaloosa had a population density of 1,285 people per square mile [496.5 people/km²].

In comparison, the 2000 Census shows Tuscaloosa had a population of 77,906 people and a land area of 56.2 square miles [145.7 km²]. This gives a population density of 1,168 people per square mile [451 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 Tuscaloosa. 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, Tuscaloosa had 40,842 Housing Units<3> and with its population of 90,468 people, this averages 2.22 people per Housing Unit.

The 2010 Census shows Tuscaloosa had a land area of 60.2 square miles [156 km²]. This translates to 580 Housing Units per square mile [224.1 housing units/km²].

From the Census of 2000: Tuscaloosa had 34,857 Housing Units, a population of 77,906 people and a land area of 56.2 square miles [145.7 km²]. This gives a density of 2.24 people per Housing Unit and 522 Housing Units per square mile [201.8 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 Tuscaloosa 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 Tuscaloosa, 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 Tuscaloosa. 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 5.48% larger than the 2000 Census.

The 2010 Census shows that the total area for Tuscaloosa was 70.4 square miles [182.2 km²]. Of this total, 60.2 square miles [156 km²] is land, with the balance (14.38%) being water (10.12 square miles [26.2 km²]).

The 2000 Census shows a total area of 66.7 square miles [172.8 km²]. Of this total, 56.2 square miles [145.7 km²] is land, with the balance (14.87%) being water (10.46 square miles [27.1 km²]).

Location ...

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

For the 2010 Census, the location was given as:

Lat:   33.233083°   (or 33°13'59" N)

Lon:   -87.525798°   (or -87°31'32" W)

For the 2000 Census, the location given was:

Lat:   33.206540°   (or 33°12'23" N)

Lon:   -87.534607°   (or -87°32'4" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 10,043 feet to the north<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 (#2405614) to Tuscaloosa. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Tuscaloosa. The GNIS point has been mapped to the latitude/longitude:

Lat:   33.235306°   (or 33°14'7" N)

Lon:   -87.527408°   (or -87°31'38" W)

The GSP location given for the 2010 Census lies 947 feet to the southeast<6> of the point given by the GNIS for Tuscaloosa. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Tuscaloosa.

Miscellaneous Information for Tuscaloosa ...

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 Tuscaloosa County or the city of Tuscaloosa:

The GNIS Codes ...

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

GNIS ID for Tuscaloosa: 2405614

GNIS ID for Tuscaloosa County: 161588

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: 125 (Tuscaloosa County)

Place Code: 77256 (Tuscaloosa)

State & County Code: 01/125 (Alabama / Tuscaloosa County)

State & Place Code: 01/77256 (Alabama / Tuscaloosa)

Misc. Census Codes ...

Tuscaloosa 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 city like Tuscaloosa, they do identify addresses that are in (or near) the city. It's important to remember that the boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes.

Our list of ZIP codes for Tuscaloosa : 35401, 35402, 35403, 35404, 35405, 35406, 35485, 35486 & 35487.<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.

For more information about the various Federal identification codes, please visit our Misc Page for Tuscaloosa.

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.
