Census Data for Simpson ...

Population ...

The most recent Census Estimate<1> was for 2018 and it gave Simpson a population of 582 people.

The last Decennial Census<2> was in 2010, which gave Simpson a population of 638 people.

The village of Simpson is located in Vernon Parish. The 2010 Census gave Vernon Parish a population of 52,334 people. This means that Simpson had 1.22% of the parish's total population, making it Vernon's 5th most populous community.

At the same time, Louisiana had a population of 4,533,372 people, meaning that Simpson had 0.01% of the total population of Louisiana - making it the state's 212nd most populous community.

Area ...

When the Census Bureau conducts a census for a village like Simpson, 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 village.

Things like the population, area and housing for Simpson reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Simpson 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 Simpson has a total area of 6.21 square miles [16.1 km²]. Of this total, a small amount of the area is covered by water (0.04 square miles [0.1 km²]).

Vernon Parish has a land area of 1,327 square miles [3,439.3 km²]. At 6.17 square miles [16 km²], Simpson has 0.46% of the parish'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:   31° 15' 22"   (or 31.26°)             [Map]

Lon:   -93° 1' 6"   (or -93.02°)

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 (638 people) and land area (6.17 square miles [16 km²]) values from the 2010 Census, Simpson had a population density of 102.8 people per square mile [39.68 people/km²].

In comparison, the 2000 Census shows Simpson had a population of 583 people and a land area of 6.21 square miles [16.1 km²]. This gives a population density of 93.7 people per square mile [36.18 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 Simpson. 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, Simpson had 288 Housing Units<3> and with its population of 638 people, this averages 2.22 people per Housing Unit.

The 2010 Census shows Simpson had a land area of 6.17 square miles [16 km²]. This translates to 46.39 Housing Units per square mile [17.91 housing units/km²].

From the Census of 2000: Simpson had 267 Housing Units, a population of 583 people and a land area of 6.21 square miles [16.1 km²]. This gives a density of 2.18 people per Housing Unit and 42.91 Housing Units per square mile [16.57 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 Simpson and you need to be careful when comparing values between the censuses. More information about 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 Simpson, 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 Simpson. 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 Simpson was 6.21 square miles [16.1 km²]. Of this total, 6.17 square miles [16 km²] is land, with the balance (0.69%) being water (0.04 square miles [0.1 km²]).

The 2000 Census shows a total area of 6.22 square miles [16.1 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 Simpson, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Simpson.

For the 2010 Census, the location was given as:

Lat:   31.256344°   (or 31°15'22" N)             [Map]

Lon:   -93.018431°   (or -93°1'6" W)

For the 2000 Census, the location given was:

Lat:   31.256010°   (or 31°15'21" N)             [Map]

Lon:   -93.018519°   (or -93°1'6" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 124.8 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 (#2407547) to Simpson. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Simpson. The GNIS point has been mapped to the latitude/longitude:

Lat:   31.258301°   (or 31°15'29" N)             [Map]

Lon:   -93.019362°   (or -93°1'9" W)

The GSP location given for the 2010 Census lies 770 feet to the southeast<6> of the point given by the GNIS for Simpson. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Simpson.

Miscellaneous Information for Simpson ...

The Federal government has assigned various identifying codes to each community, county, parish and state. At one time or another, the US Census Bureau has used one (or more) of the following identifiers when referring to either Vernon Parish or the village of Simpson:

The GNIS Codes ...

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

GNIS ID for Simpson: 2407547

GNIS ID for Vernon Parish: 559548

GNIS ID for Louisiana: 1629543

The FIPS Codes ...

An earlier (and largely obsolete) identification method was called the Federal Information Processing Standard (FIPS):

State Code: 22 (Louisiana)

County Code: 115 (Vernon Parish)

Place Code: 70595 (Simpson)

State & County Code: 22/115 (Louisiana / Vernon Parish)

State & Place Code: 22/70595 (Louisiana / Simpson)

Misc. Census Codes ...

Simpson is located in Census Region #3 (the South Region) and Division #7 (the West 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 village like Simpson, it does identify addresses that are in (or near) Simpson. 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 Simpson: 71474<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.

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 2018.

- 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.

<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.
