    • When the Census Bureau conducts a census for a city like Kadoka, they draw a boundary around the area in which they are going to conduct their count - this defines the sampling area (usually 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 population, area and housing for Kadoka reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Kadoka might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.
    • 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:   43° 49' 37"   (or 43.83°)
    • Lon:   -101° 30' 18"   (or -101.51°)
    • 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).

Housing Units ...

At the time of the 2010 Census, Kadoka had 350 Housing Units<3> and with its population of 654 people, this averages 1.87 people per Housing Unit.

  • Continue Reading ...
    • The 2010 Census shows Kadoka had a land area of 2.29 square miles [5.9 km²]. This translates to 151.3 Housing Units per square mile [58.4 housing units/km²].
    • From the Census of 2000: Kadoka had 356 Housing Units, a population of 706 people and a land area of 2.31 square miles [6 km²]. This gives a density of 1.98 people per Housing Unit and 153.7 Housing Units per square mile [59.4 housing units/km²].
    • Note: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2010 and the 2000 Census, there were changes in the sampling area for Kadoka and you need to be careful when comparing numbers between the censuses. More information about these differences 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 Kadoka, 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 Kadoka. It's important to note that from one Census to the next, the shape and location of the polygon can change.

  • Continue Reading ...
    • Although we don't have specific information about the shape of the polygon for Kadoka or how it changed has over time, there is some information that can give us some hints. For example, since the shape of the sampling area is directly related to the shape of the polygon, any change to area probably indicates a new shape for the polygon.
    • If you need precision or details about the methodology of the Census, you should visit the U.S. Census Bureau for a definitive answer.

Location ...

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

  • Continue Reading ...
    • For the 2010 Census, the location was given as:
    • Lat:   43.827002°   (or 43°49'37" N)
    • Lon:   -101.505251°   (or -101°30'18" W)
    • For the 2000 Census, the location given was:
    • Lat:   43.835290°   (or 43°50'7" N)
    • Lon:   -101.512333°   (or -101°30'44" W)
    • The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 3,549 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 (#1267442) to Kadoka. This identifier also marks a GPS point on the map, and that point lies within the boundaries of Kadoka. The GNIS point has been mapped to the latitude/longitude:
    • Lat:   43.831938°   (or 43°49'54" N)
    • Lon:   -101.509310°   (or -101°30'33" W)
    • The GPS location given for the 2010 Census lies 2,092 feet to the southeast<6> of the point given by the GNIS for Kadoka. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Kadoka.

Miscellaneous Information for Kadoka ...

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 Jackson County or the city of Kadoka:

  • The GNIS Codes ...
    • The current system of identification is called the Geographic Names Information System (GNIS). The following GNIS codes relate to Kadoka:
    • GNIS ID for Kadoka: 1267442
    • GNIS ID for Jackson County: 1265794
    • GNIS ID for State of South Dakota: 1785534
  • Misc. Census Codes ...
    • Kadoka is located in Census Region #2 (the Midwest Region) and Division #4 (the West North-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 Kadoka, it does identify addresses that are in (or near) Kadoka. 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 Kadoka:57543<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 2019.
<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>If you're interested in how the shape of South Dakota's counties, including Jackson, have changed over time, we recommend the Atlas of Historical County Boundaries.
<5>The calculated bearing (or angle) to the 2010 Census location is 211 degrees and a distance of 3,549 feet.
<6>The calculated bearing (or angle) to the GNIS point is 210 degrees and a distance of 2,092 feet.
<7>When looking for a ZIP Code, whether Kadoka or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
