  • When the Census Bureau conducts a census for a town like Brockton, 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 town.
  • Things like population, area and housing for Brockton reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Brockton 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:   48° 9' 0"   (or 48.15°)
  • Lon:   -104° 54' 50"   (or -104.91°)

Census-to-Census Observations ...

Introduction ...

When the Census Bureau takes a census count (or enumeration) for Brockton, 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 Brockton. 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 Brockton 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.

• The GNIS Codes ...
  • The current system of identification is called the Geographic Names Information System (GNIS). The following GNIS codes relate to Brockton:
  • GNIS ID for Brockton: 2411730
  • GNIS ID for Roosevelt County: 1669428
  • GNIS ID for State of Montana: 767982

• The FIPS Codes ...
  • An earlier (and largely obsolete) identification method was called the Federal Information Processing Standard (FIPS):
  • State Code: 30 (Montana)
  • County Code: 085 (Roosevelt County)
  • Place Code: 10000 (Brockton)
  • State & County Code: 30/085 (Montana / Roosevelt County)
  • State & Place Code: 30/10000 (Montana / Brockton)

• Misc. Census Codes ...
  • Brockton is located in Census Region #4 (the West Region) and Division #8 (the Mountain 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 town like Brockton, it does identify addresses that are in (or near) Brockton. 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 Brockton:59213<6>

• 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.
