The last Decennial Census<2> was in 2010, giving Hanford a population of 53,967 people.

The city of Hanford is located in Kings County. The 2010 Census gave Kings County a population of 152,982 people. This means that Hanford had 35.28% of the county's total population, making it Kings' most populous community.

Area ...

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

Things like the population, area and housing for Hanford reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Hanford 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 Hanford has a total area of 16.59 square miles [43 km²].

Kings County has a land area of 1,389 square miles [3,598.6 km²]. At 16.59 square miles [43 km²], Hanford has 1.19% 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:   36° 19' 34"   (or 36.33°)             [Map]

Lon:   -119° 39' 14"   (or -119.65°)

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 (53,967 people) and land area (16.59 square miles [43 km²]) values from the 2010 Census, Hanford had a population density of 3,253 people per square mile [1,256 people/km²].

In comparison, the 2000 Census shows Hanford had a population of 41,686 people and a land area of 13.09 square miles [33.9 km²]. This gives a population density of 3,184 people per square mile [1,229 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 Hanford. You need to be careful when making such a comparison, the differences are likely to lead to a questionable 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, Hanford had 18,493 Housing Units<3> and with its population of 53,967 people, this averages 2.92 people per Housing Unit.

The 2010 Census shows Hanford had a land area of 16.59 square miles [43 km²]. This translates to 1,114 Housing Units per square mile [430.4 housing units/km²].

From the Census of 2000: Hanford had 14,721 Housing Units, a population of 41,686 people and a land area of 13.09 square miles [33.9 km²]. This gives a density of 2.83 people per Housing Unit and 1,124 Housing Units per square mile [434.2 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 Hanford and you need to be careful when comparing 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 Hanford, 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 Hanford. 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 26.72% larger than the 2000 Census.

The 2010 Census shows that the total area for Hanford was 16.59 square miles [43 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 13.09 square miles [33.9 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 Hanford, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Hanford.

For the 2010 Census, the location was given as:

Lat:   36.326135°   (or 36°19'34" N)             [Map]

Lon:   -119.654010°   (or -119°39'14" W)

For the 2000 Census, the location given was:

Lat:   36.333273°   (or 36°19'59" N)             [Map]

Lon:   -119.646889°   (or -119°38'48" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 3,338 feet to the southwest<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 (#2410696) to Hanford. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Hanford. The GNIS point has been mapped to the latitude/longitude:

Lat:   36.326951°   (or 36°19'37" N)             [Map]

Lon:   -119.650930°   (or -119°39'3" W)

The GSP location given for the 2010 Census lies 952 feet to the west<6> of the point given by the GNIS for Hanford. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Hanford.

Miscellaneous Information for Hanford ...

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

The GNIS Codes ...

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

GNIS ID for Hanford: 2410696

GNIS ID for Kings County: 277280

GNIS ID for California: 1779778

The FIPS Codes ...

State Code: 06 (California)

County Code: 031 (Kings County)

Place Code: 31960 (Hanford)

State & County Code: 06/031 (California / Kings County)

State & Place Code: 06/31960 (California / Hanford)

Misc. Census Codes ...

Hanford is located in Census Region #4 (the West Region) and Division #9 (the Pacific Division).

US Postal Service ZIP Codes ...

While some people have used ZIP codes to identify a community, the ZIP codes were actually created to make mail delivery more efficient by grouping addresses together. Although a ZIP Code doesn't specifically identify a city like Hanford, they do identify addresses that are in (or near) the city. It's important to remember that the boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes.

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.

<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.
