  • When the Census Bureau conducts a census for a city like Bartlesville, 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 Bartlesville reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Bartlesville 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:   36° 44' 17"   (or 36.74°)
  • Lon:   -95° 56' 52"   (or -95.95°)

  • Note: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2010 Census and the 2000 Census, there were changes in the sampling area for Bartlesville and you need to be careful when comparing values between the censuses.

Census-to-Census Observations ...

Introduction ...

When the Census Bureau takes a census count (or enumeration) for Bartlesville, 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 Bartlesville. It's important to note that from one Census to the next, the shape and location of the polygon can change.

  • Although we don't have specific information about the shape of the polygon for Bartlesville 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 Bartlesville, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Bartlesville.

Miscellaneous Information for Bartlesville ...

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 Washington County or the city of Bartlesville:

• The GNIS Codes ...
  • The current system of identification is called the Geographic Names Information System (GNIS). The following GNIS codes relate to Bartlesville:
  • GNIS ID for Bartlesville: 2409792
  • GNIS ID for Washington County: 1101861
  • GNIS ID for State of Oklahoma: 1102857

• The FIPS Codes ...
  • An earlier (and largely obsolete) identification method was called the Federal Information Processing Standard (FIPS):
  • State Code: 40 (Oklahoma)
  • County Code: 147 (Washington County)
  • Place Code: 04450 (Bartlesville)
  • State & County Code: 40/147 (Oklahoma / Washington County)
  • State & Place Code: 40/04450 (Oklahoma / Bartlesville)

• Misc. Census Codes ...
  • Bartlesville 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 Bartlesville, it does identify addresses that are in (or near) Bartlesville. 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 Bartlesville:74003<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.
