The most recent Census Estimate<1> was for 2016 and it gives Clio a population of 1,470 people.

The last Decennial Census<2> was in 2010, giving Clio a population of 1,399 people.

The city of Clio is located in Barbour County. The 2010 Census gave Barbour County a population of 27,457 people. This means that Clio had 5.1% of the county's total population, making it Barbour's 3rd most populous community.

At the same time, Alabama had a population of 4,779,736 people, meaning that Clio had 0.03% of the total population of Alabama - making it the state's 221st most populous community.

Area ...

When the Census Bureau conducts a census for a city like Clio, 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 Clio reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Clio 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 Clio has a total area of 10.08 square miles [26.1 km²]. Of this total, a small amount of the area is covered by water (0 square miles [0 km²]).

Barbour County has a land area of 884 square miles [2,291.8 km²]. At 10.07 square miles [26.1 km²], Clio has 1.14% 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° 42' 30"   (or 31.71°)             [Map]

Lon:   -85° 36' 39"   (or -85.61°)

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 (1,399 people) and land area (10.07 square miles [26.1 km²]) values from the 2010 Census, Clio had a population density of 138.9 people per square mile [53.6 people/km²].

In comparison, the 2000 Census shows Clio had a population of 2,206 people and a land area of 10.06 square miles [26 km²]. This gives a population density of 219.2 people per square mile [84.6 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 Clio. You need to be careful when making such a comparison, the differences are likely to lead to a questionable 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, Clio had 634 Housing Units<3> and with its population of 1,399 people, this averages 2.21 people per Housing Unit.

The 2010 Census shows Clio had a land area of 10.07 square miles [26.1 km²]. This translates to 62.9 Housing Units per square mile [24.3 housing units/km²].

From the Census of 2000: Clio had 527 Housing Units, a population of 2,206 people and a land area of 10.06 square miles [26 km²]. This gives a density of 4.19 people per Housing Unit and 52.4 Housing Units per square mile [20.22 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 Clio and you need to be careful when comparing 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 Clio, 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 Clio. 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 ...

There is only a very minor difference in the sampling area given between the 2010 Census and the 2000 Census.

The 2010 Census shows that the total area for Clio was 10.08 square miles [26.1 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 10.06 square miles [26.1 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 Clio, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Clio.

For the 2010 Census, the location was given as:

Lat:   31.708516°   (or 31°42'30" N)             [Map]

Lon:   -85.611039°   (or -85°36'39" W)

For the 2000 Census, the location given was:

Lat:   31.709922°   (or 31°42'35" N)             [Map]

Lon:   -85.606708°   (or -85°36'24" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 1,437 feet to the west<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 (#2404082) to Clio. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Clio. The GNIS point has been mapped to the latitude/longitude:

Lat:   31.708553°   (or 31°42'30" N)             [Map]

Lon:   -85.610910°   (or -85°36'39" W)

The GSP location given for the 2010 Census lies 42.22 feet to the west<6> of the point given by the GNIS for Clio. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Clio.

Miscellaneous Information for Clio ...

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 Barbour County or the city of Clio:

The GNIS Codes ...

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

GNIS ID for Clio: 2404082

GNIS ID for Barbour County: 161528

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: 005 (Barbour County)

Place Code: 15640 (Clio)

State & County Code: 01/005 (Alabama / Barbour County)

State & Place Code: 01/15640 (Alabama / Clio)

Misc. Census Codes ...

Clio 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 Clio, it does identify addresses that are in (or near) Clio. 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 Clio: 36017<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.

<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.
