Census Data for County Line ...

Population ...

The most recent Census Estimate<1> was for 2017 and it gives County Line a population of 264 people.

The last Decennial Census<2> was in 2010, giving County Line a population of 258 people.

The town of County Line is located in Blount County. The 2010 Census gave Blount County a population of 57,322 people. This means that County Line had 0.45% of the county's total population, making it Blount's 12th most populous community.

At the same time, Alabama had a population of 4,779,736 people.

Area ...

When the Census Bureau conducts a census for a town like County Line, 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 County Line reflect the sampling area. Since the shape of the sampling area and the actual boundaries of County Line 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 County Line has a total area of 0.96 square miles [2.5 km²].

Blount County has a land area of 644 square miles [1,670 km²]. At 0.96 square miles [2.5 km²], County Line has 0.15% 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° 49' 15"   (or 33.82°)             [Map]

Lon:   -86° 43' 11"   (or -86.72°)

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 (258 people) and land area (0.96 square miles [2.5 km²]) values from the 2010 Census, County Line had a population density of 267.4 people per square mile [103.2 people/km²].

In comparison, the 2000 Census shows County Line had a population of 257 people and a land area of 0.95 square miles [2.5 km²]. This gives a population density of 270.5 people per square mile [104.4 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 County Line. You need to be careful when making such a comparison, the differences are likely to lead to an incorrect 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, County Line had 118 Housing Units<3> and with its population of 258 people, this averages 2.19 people per Housing Unit.

The 2010 Census shows County Line had a land area of 0.96 square miles [2.5 km²]. This translates to 122.3 Housing Units per square mile [47.21 housing units/km²].

From the Census of 2000: County Line had 106 Housing Units, a population of 257 people and a land area of 0.95 square miles [2.5 km²]. This gives a density of 2.42 people per Housing Unit and 111.6 Housing Units per square mile [43.08 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 County Line 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).

Census-to-Census Observations ...

Introduction ...

When the Census Bureau takes a census count (or enumeration) for County Line, 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 County Line. 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 1.57% larger than the 2000 Census.

The 2010 Census shows that the total area for County Line was 0.96 square miles [2.5 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 0.95 square miles [2.5 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 County Line, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for County Line.

For the 2010 Census, the location was given as:

Lat:   33.820894°   (or 33°49'15" N)             [Map]

Lon:   -86.719734°   (or -86°43'11" W)

For the 2000 Census, the location given was:

Lat:   33.819645°   (or 33°49'10" N)             [Map]

Lon:   -86.729287°   (or -86°43'45" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 2,929 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 (#116712) to County Line. This identifier also marks a GSP point on the map, and that point lies within the boundaries of County Line. The GNIS point has been mapped to the latitude/longitude:

Lat:   33.821489°   (or 33°49'17" N)             [Map]

Lon:   -86.718604°   (or -86°43'6" W)

The GSP location given for the 2010 Census lies 405.2 feet to the southwest<6> of the point given by the GNIS for County Line. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for County Line.

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 2017.

<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.

<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.
