- When the Census Bureau conducts a census for a city like Maricopa, 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 Maricopa reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Maricopa 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: 33° 2' 43" (or 33.05°)
- Lon: -112° 0' 55" (or -112.02°)

Census-to-Census Observations ...
Introduction ...
When the Census Bureau takes a census count (or enumeration) for Maricopa, 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 Maricopa. 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 Maricopa 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 Maricopa, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Maricopa.

- For the 2010 Censuses, the location was given as:
Lat: 33.045487° (or 33°2'43" N)
- The U.S. Geological Survey (USGS) and the U.S. Board on Geographic Names (BGN) have assigned a unique GNIS identifier (#2411032) to Maricopa. This identifier also marks a GPS point on the map, and that point lies within the boundaries of Maricopa. The GNIS point has been mapped to the latitude/longitude:

Miscellaneous Information for Maricopa ...
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 Pinal County or the city of Maricopa:
- The GNIS Codes ...
- The FIPS Codes ...
- An earlier (and largely obsolete) identification method was called the Federal Information Processing Standard (FIPS):
- State Code: 04 (Arizona)
- County Code: 021 (Pinal County)
- Place Code: 44410 (Maricopa)
- State & County Code: 04/021 (Arizona / Pinal County)
- State & Place Code: 04/44410 (Arizona / Maricopa)
- Misc. Census Codes ...
- Maricopa 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 city like Maricopa, it does identify addresses that are in (or near) Maricopa. 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 Maricopa:85239<5>
- 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 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. |
| <2> | 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). |
| <3> | If you're interested in how the shape of Arizona's counties, including Pinal, have changed over time, we recommend the Atlas of Historical County Boundaries. |
| <4> | The calculated bearing (or angle) to the GNIS point is 82 degrees and a distance of 7,567 feet. |
