Area ...

When the Census Bureau conducts a census for a city like South Houston, 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 city.

Things like the population, area and housing for South Houston reflect the sampling area. Since the shape of the sampling area and the actual boundaries of South Houston 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 South Houston has a total area of 3.05 square miles [7.9 km²].

Harris County has a land area of 1,703 square miles [4,412 km²]. At 3.05 square miles [7.9 km²], South Houston has 0.18% 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:   29° 39' 39"   (or 29.66°)             [Map]

Lon:   -95° 13' 42"   (or -95.23°)

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 (16,983 people) and land area (3.05 square miles [7.9 km²]) values from the 2010 Census, South Houston had a population density of 5,564 people per square mile [2,148 people/km²].

In comparison, the 2000 Census shows South Houston had a population of 15,833 people and a land area of 3.03 square miles [7.8 km²]. This gives a population density of 5,231 people per square mile [2,019 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 South Houston. You need to be careful when making such a comparison, the differences are likely to lead to an apple-to-oranges comparison. More information about the nature of these changes can be found in the section Census-to-Census Observations ... (see below).

Housing Units ...

At the time of the 2010 Census, South Houston had 5,258 Housing Units<3> and with its population of 16,983 people, this averages 3.23 people per Housing Unit.

The 2010 Census shows South Houston had a land area of 3.05 square miles [7.9 km²]. This translates to 1,722 Housing Units per square mile [665 housing units/km²].

From the Census of 2000: South Houston had 4,947 Housing Units, a population of 15,833 people and a land area of 3.03 square miles [7.8 km²]. This gives a density of 3.2 people per Housing Unit and 1,634 Housing Units per square mile [631 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 South Houston and you need to be careful when comparing results 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 South Houston, 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 South Houston. 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 0.84% larger than the 2000 Census.

The 2010 Census shows that the total area for South Houston was 3.05 square miles [7.9 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 3.03 square miles [7.8 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 South Houston, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for South Houston.

For the 2010 Census, the location was given as:

Lat:   29.661024°   (or 29°39'39" N)             [Map]

Lon:   -95.228361°   (or -95°13'42" W)

For the 2000 Census, the location given was:

Lat:   29.660980°   (or 29°39'39" N)             [Map]

Lon:   -95.229787°   (or -95°13'47" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 452.1 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 (#2411936) to South Houston. This identifier also marks a GSP point on the map, and that point lies within the boundaries of South Houston. The GNIS point has been mapped to the latitude/longitude:

Lat:   29.661126°   (or 29°39'40" N)             [Map]

Lon:   -95.228494°   (or -95°13'42" W)

The GSP location given for the 2010 Census lies 56.2 feet to the southeast<6> of the point given by the GNIS for South Houston. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for South Houston.

Miscellaneous Information for South Houston ...

The Federal government has assigned various identifying codes to each community, county and state. At one time or another, the US Census Bureau has used one (or more) of the following identifiers when referring to either Harris County or the city of South Houston:

The GNIS Codes ...

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

GNIS ID for South Houston: 2411936

GNIS ID for Harris County: 1383886

GNIS ID for Texas: 1779801

The FIPS Codes ...

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

State Code: 48 (Texas)

County Code: 201 (Harris County)

Place Code: 69020 (South Houston)

State & County Code: 48/201 (Texas / Harris County)

State & Place Code: 48/69020 (Texas / South Houston)

Misc. Census Codes ...

South Houston 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 city like South Houston, it does identify addresses that are in (or near) South Houston. 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 South Houston: 77587<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.

<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.
