The town of Argo is located in Saint Clair County. The 2010 Census gave Saint Clair County a population of 83,593 people. This means that Argo had 4.87% of the county's total population, making it Saint Clair's 5th most populous community.

Area ...

When the Census Bureau conducts a census for a town like Argo, 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 Argo reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Argo 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 Argo has a total area of 10.83 square miles [28.1 km²]. Of this total, a small amount of the area is covered by water (0.06 square miles [0.2 km²]).

Saint Clair County has a land area of 784 square miles [2,033 km²]. At 10.77 square miles [27.9 km²], Argo has 1.37% 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° 41' 28"   (or 33.69°)             [Map]

Lon:   -86° 30' 19"   (or -86.51°)

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 (4,071 people) and land area (10.77 square miles [27.9 km²]) values from the 2010 Census, Argo had a population density of 375.9 people per square mile [145.1 people/km²].

In comparison, the 2000 Census shows Argo had a population of 1,780 people and a land area of 12.17 square miles [31.5 km²]. This gives a population density of 145.1 people per square mile [56 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 Argo. You need to be careful when making such a comparison, the differences are likely to lead to a misleading comparison. More information about these differences can be found in the section Census-to-Census Observations ... (see below).

Housing Units ...

At the time of the 2010 Census, Argo had 1,492 Housing Units<3> and with its population of 4,071 people, this averages 2.73 people per Housing Unit.

The 2010 Census shows Argo had a land area of 10.77 square miles [27.9 km²]. This translates to 137.8 Housing Units per square mile [53.2 housing units/km²].

From the Census of 2000: Argo had 726 Housing Units, a population of 1,780 people and a land area of 12.17 square miles [31.5 km²]. This gives a density of 2.45 people per Housing Unit and 59.2 Housing Units per square mile [22.85 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 Argo 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 Argo, 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 Argo. 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 11.71% smaller than the 2000 Census.

The 2010 Census shows that the total area for Argo was 10.83 square miles [28.1 km²]. Of this total, 10.77 square miles [27.9 km²] is land, with the balance (0.54%) being water (0.06 square miles [0.2 km²]).

The 2000 Census shows a total area of 12.27 square miles [31.8 km²]. Of this total, 12.17 square miles [31.5 km²] is land, with the balance (0.9%) being water (0.1 square miles [0.3 km²]).

Location ...

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

For the 2010 Census, the location was given as:

Lat:   33.691132°   (or 33°41'28" N)             [Map]

Lon:   -86.505436°   (or -86°30'19" W)

For the 2000 Census, the location given was:

Lat:   33.700210°   (or 33°42'0" N)             [Map]

Lon:   -86.512357°   (or -86°30'44" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 3,919 feet to the southeast<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 (#2405164) to Argo. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Argo. The GNIS point has been mapped to the latitude/longitude:

Lat:   33.696636°   (or 33°41'47" N)             [Map]

Lon:   -86.508562°   (or -86°30'30" W)

The GSP location given for the 2010 Census lies 2,219 feet to the southeast<6> of the point given by the GNIS for Argo. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Argo.

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 2016.

<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.
