The town of Poca is located in Putnam County. The 2010 Census gave Putnam County a population of 55,486 people. This means that Poca had 1.76% of the county's total population, making it Putnam's 5th most populous community.

Area ...

When the Census Bureau conducts a census for a town like Poca, they draw a boundary around the area in which they are going to conduct their count - this defines the sampling area (usually shaped as 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 Poca reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Poca might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.

The 2010 Census shows that the sampling area for Poca has a total area of 0.75 square miles [2 km²]. Of this total, 0.59 square miles [1.5 km²] is land, with the balance (22.05%) being water (0.17 square miles [0.4 km²]).

Putnam County has a land area of 345.7 square miles [895.3 km²]. At 0.59 square miles [1.5 km²], Poca has 0.17% 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 the center of the polygon, known as the centroid). At the time of the 2010 Census, the sampling area was located at:

Lat:   38° 28' 18"   (or 38.47°)             [Map]

Lon:   -81° 48' 43"   (or -81.81°)

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 (974 people) and land area (0.59 square miles [1.5 km²]) values from the 2010 Census, Poca had a population density of 1,293 people per square mile [499.4 people/km²].

In comparison, the 2000 Census shows Poca had a population of 1,013 people and a land area of 0.56 square miles [1.5 km²]. This gives a population density of 1,400 people per square mile [540 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 Poca. You need to be careful when making such a comparison, the differences are likely to lead to a questionable 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, Poca had 415 Housing Units<3> and with its population of 974 people, this averages 2.35 people per Housing Unit.

The 2010 Census shows Poca had a land area of 0.59 square miles [1.5 km²]. This translates to 551 Housing Units per square mile [212.8 housing units/km²].

From the Census of 2000: Poca had 430 Housing Units, a population of 1,013 people and a land area of 0.56 square miles [1.5 km²]. This gives a density of 2.36 people per Housing Unit and 594 Housing Units per square mile [229.5 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 Poca 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 Poca, 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 Poca. 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 4.07% larger than the 2000 Census.

The 2010 Census shows that the total area for Poca was 0.75 square miles [2 km²]. Of this total, 0.59 square miles [1.5 km²] is land, with the balance (22.05%) being water (0.17 square miles [0.4 km²]).

The 2000 Census shows a total area of 0.72 square miles [1.9 km²]. Of this total, 0.56 square miles [1.5 km²] is land, with the balance (21.6%) being water (0.16 square miles [0.4 km²]).

Location ...

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

For the 2010 Census, the location was given as:

Lat:   38.471718°   (or 38°28'18" N)             [Map]

Lon:   -81.812210°   (or -81°48'43" W)

For the 2000 Census, the location given was:

Lat:   38.461343°   (or 38°27'40" N)             [Map]

Lon:   -81.815592°   (or -81°48'56" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 3,903 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 (#2391364) to Poca. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Poca. The GNIS point has been mapped to the latitude/longitude:

Lat:   38.472979°   (or 38°28'22" N)             [Map]

Lon:   -81.812477°   (or -81°48'44" W)

The GSP location given for the 2010 Census lies 466 feet to the south<6> of the point given by the GNIS for Poca. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Poca.

<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.
