- When the Census Bureau conducts a census for a community like Bridgeport, 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 community.
- Things like population, area and housing for Bridgeport reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Bridgeport 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: 40° 6' 14" (or 40.1°)
- Lon: -75° 20' 36" (or -75.34°)
- 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).

- 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 Bridgeport and you need to be careful when comparing results between the censuses. More information about the nature of these 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 Bridgeport, 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 Bridgeport. 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 Bridgeport 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 Bridgeport, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Bridgeport.
- Continue Reading ...
- For the 2010 Census, the location was given as:
- Lat: 40.104072° (or 40°6'14" N)
- Lon: -75.343550° (or -75°20'36" W)
- For the 2000 Census, the location given was:
- Lat: 40.103875° (or 40°6'13" N)
- Lon: -75.343188° (or -75°20'35" W)
- The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 123.9 feet to the northwest<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 (#1215464) to Bridgeport. This identifier also marks a GPS point on the map, and that point lies within the boundaries of Bridgeport. The GNIS point has been mapped to the latitude/longitude:
- Lat: 40.103442° (or 40°6'12" N)
- Lon: -75.342406° (or -75°20'32" W)
- The GPS location given for the 2010 Census lies 393.1 feet to the northwest<6> of the point given by the GNIS for Bridgeport. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Bridgeport.
Miscellaneous Information for Bridgeport ...
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 Montgomery County or the community of Bridgeport:

- Place Code: 08568 (Bridgeport)
- State & County Code: 42/091 (Pennsylvania / Montgomery County)
- State & Place Code: 42/08568 (Pennsylvania / Bridgeport)

- 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 community like Bridgeport, it does identify addresses that are in (or near) Bridgeport. 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 Bridgeport:19405<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). |
