Frequently Asked Questions

Why are there instances of fragmented or discontiguous three-digit ZCTAs?

U.S. Census Bureau ZIP Code Tabulation Areas - FAQs
The USPS may assign several three-digit ZIP Codes to the areas around some cities. The five-digit ZIP Codes within these areas are distributed across the area and do not form specific three-digit clusters. To identify these areas see the USPS maps of three-digit ZIP Codes, located in the 2000 National Five-Digit ZIP Code and Post Office Directory USPS publication 65. The maps show certain areas with multiple three-digit ZIP Codes.

Why do some ZCTAs form discontiguous areas?

U.S. Census Bureau ZIP Code Tabulation Areas - FAQs
Discontiguous parts of ZCTAs may represent offshore islands. In other situations, they may result from using census blocks to build ZCTAs. United States Postal Service (USPS) carrier routes tend to extend out along the local street network. Addresses along a street may have one ZIP Code while addresses along the cross streets have another.

U.S. Census Bureau ZIP Code Tabulation Areas - FAQs
Geographic descriptions of ZCTAs will initially appear in the Census 2000 TIGER/Line® files in the third quarter of 2001. Tabulations containing ZCTAs appeared on the Internet and in CD-ROM products beginning with Summary File 1 (SF1) in the summer of 2001 and in Summary File 3 (SF3) released in the summer of 2002.

There are 33,178 ZCTAs nationwide (all 50 states, the District of Columbia and Puerto Rico), including generic three-digit ZCTAs. Of that total, 32,038 ZCTAs carry the full five-digit numeric ZIP Code. The remainder will have a generic code ending in either “HH” or “ XX” suffix.
Related Questions

Are there size limitations to ZCTAs?

U.S. Census Bureau ZIP Code Tabulation Areas - FAQs
Currently, there are no restrictions limiting how large or small a ZCTA can be in terms of either a minimum/maximum number of housing units or geographic area. ZCTAs reflect the areas where we find addresses with the specified ZIP Code. As a result, ZCTAs may be as small as a few city blocks or cover many square miles.
Related Questions

Are there plans to update ZCTAs in the future?

U.S. Census Bureau ZIP Code Tabulation Areas - FAQs
For the 2003 TIGER/LineŽ files, the U.S. Census Bureau produced updated national current ZCTAs reflecting USPS ZIP Code changes through October, 2002. The United States Postal Service (USPS) makes periodic changes to ZIP Codes to support more efficient mail delivery. Therefore, the original Census 2000 ZCTAs may no longer match current ZIP Codes. As a result of the updates, 581 ZCTAs were eliminated and 735 new ZCTAs were created, for a new nationwide total of 33,322 ZCTAs.

Related Questions

Why are there ZCTAs for some dedicated PO Box ZIP Codes and not for others?

U.S. Census Bureau ZIP Code Tabulation Areas - FAQs
Dedicated PO Box ZIP Codes present a special challenge for ZCTA delineation. While addresses with these ZIP Codes generally cluster around a post office, they may also be widely scattered. Additionally, there may be the option of regular/street delivery present in the areas around these post offices, resulting in a mix of valid USPS ZIP Code options for residents.
Related Questions

Do ZCTAs reflect commercial ZIP Codes?

U.S. Census Bureau ZIP Code Tabulation Areas - FAQs
The ZCTA delineation process included both residential and commercial addresses. A ZIP Code representing a commercial district may appear as a ZCTA if the ZIP Code serves the majority of the addresses for the census blocks in the area. However, individual firms or organizations with their own ZIP Codes are automatically excluded and do not become ZCTAs. There are 2,523 of these unique ZIP Codes excluded from Census 2000 ZCTA delineation.
Related Questions

What do the ZCTAs with an "XX" or "HH"suffix represent?

U.S. Census Bureau ZIP Code Tabulation Areas - FAQs
The three-digit ZCTA code and an "XX" suffix are applied to a large land area (generally larger than 25 square miles) where we had insufficient information to determine the five-digit codes. The USPS may not provide five-digit ZIP Code delivery service in this area. These are generally rural areas with little settlement; for example, parks, forest lands, and desert and mountainous areas.
Related Questions

Why do some ZCTAs ending in "HH" contain land area?

U.S. Census Bureau ZIP Code Tabulation Areas - FAQs
After Census 2000, efforts to improve the spatial accuracy of the TIGER database have and continue to add land area such as small islands or sections of shoreline to census blocks that were entirely water in Census 2000. Census 2000 tabulation census blocks once consisting entirely of water features may now contain a mix of water and small land features. As a result, "HH" ZCTA codes may no longer represent purely water areas.

How can I find coordinates (Latitude and Longitude) for ZCTAs based on centroid?

U.S. Census Bureau ZIP Code Tabulation Areas - FAQs
The downloadable ZCTA gazetteer files contain the latitude/longitude coordinates for each Census 2000 ZCTA. Coordinates for ZCTA internal points (calculated by considering the latitude/longitude of all bounding features and then creating an area-weighted average point inside the polygon) are also available in the TIGER/Line® Files.

I've heard that after many recordings and edits an MD can become fragmented, is this a problem?

Minidisc Frequently Asked Questions
My comments are with reference to modern MD machines (ca. 1996), I am unfamiliar with the behavior of the older units. I am also speaking based upon my observation of simple experiments on an MDS-503, not on any intimate knowledge of MD technical specifications. There are two potential problems with fragmentation: interruption of music due to excessive seeking, and loss of free space. Concerning interruption of music, fragmentation alone will not cause a problem.
