Census 2000 1-Percent Public Use Microdata Area (PUMA1) Shapefile & Census 2000 5- or 10-Percent Public Use Microdata Area (PUMA5) Shapefile

In the past the Public Use Microdata Areas have been named based on the sample size (1-percent, 5-percent, or 10-percent) but they have been renamed Super Public Use Microdata Area or Public Use Microdata Area.  The name Public Use Microdata Area refers to the areas formerly known as the 5-percent or 10-percent Public Use Microdata Area.  The name Super Public Use Microdata Area refers to the areas formerly known as the 1-Percent Public Use Microdata Area.  This change affects the naming convention of 2 shapefiles beginning with the 2009 Public TIGER/Line Shapefiles.

The Census 2000 1-Percent Public Use Microdata Area (PUMA1) Shapefile has been renamed Census 2000 Super Public Use Microdata Area (Super PUMA) Shapefile

The Census 2000 5- or 10-Percent Public Use Microdata Area (PUMA5) Shapefile has been renamed Census 2000 Public Use Microdata Area (PUMA) Shapefile

Due to the name change of the 1-Percent Public Use Microdata Area to Super PUMA, the full name of the Super PUMA does not appear in the attribute table.  The NAMELSAD00 field, which normally contains the full name, contains only “Super PUMA”.  The PUMA number can be obtained from the PUMA1CE00 field.  To create the fully qualified name, concatenate the NAMELSAD00 field and the PUMA1CE00 field.

Topological Faces (2-Cells With All Geocodes) Relationship File is now a shapefile and has been renamed.  The new name is: Topological Faces (Polygons With All Geocodes) Shapefile
In addition, the following new fields have been added:

• American Indian/Alaska Native/Native Hawaiian FIPS Codes (AIANNHFP00 and AIANNHFP)
• Tribal Subdivision FIPS Codes (TRSUBFP00 and TRSUBFP)
• Total Area (ATOTAL)
• Internal Point Coordinates (INTPTLAT and INTPTLON)

The 111th Congressional District Shapefile has replaced the 110th Congressional District Shapefile.  There were no boundary changes between the 110th and 111th Congresses.

For the 2009 TIGER/Line Shapefile release 15 new State-based Shapefiles have been added, they are as follows:

• American Indian/Alaska Native/Native Hawaiian Area (AIANNH) State-based Shapefile (Census 2000 and Current)
• American Indian Tribal Subdivision (AITS) State-based Shapefile (Census 2000 and Current)
• Combined Statistical Area (CSA) State-based Shapefile (Current)
• Metropolitan Statistical Area/Micropolitan Statistical Area (CBSA) State-based Shapefile (Current)
• Metropolitan Division State-based Shapefile (Current)
• Combined New England City and Town Area (CNECTA) State-based Shapefile (Current)
• New England City and Town Area (NECTA) State-based Shapefile (Current)
• New England City and Town Area (NECTA) Division State-based Shapefile (Current)
• State and Equivalent State-based Shapefile (Census 2000 and Current)
• Military Installation State-based Shapefile
• 5-Digit ZIP Code Tabulation Area (ZCTA5) State-based Shapefile (2002) – not clipped (can extend beyond the state boundary)
• 3-Digit ZIP Code Tabulation Area (ZCTA3) State-based Shapefile (2002) – not clipped (can extend beyond the state boundary)

The All Lines Shapefile (Edges) includes all linear feature geography such as roads (street features), railroads, hydrography, and other linear features.  The All Lines Shapefile is available at the county level only.  There are several attribute flags within the shapefile that indicate if the feature is a road, rail, or water.  Each edge has a unique TLID (TIGER/Line identifier) value.
More detailed information regarding the All Lines Shapefile can be found in the technical documentation.

The Spatial Metadata Identifier (SMID) in the All Lines shapefile identifies the source of the coordinates for the line segment when available (not every edge will have a SMID) and provides the link between the TIGER/Line Shapefile and the source and horizontal spatial accuracy information. There are a few occurrences where the SMIDs are missing from some All Lines metadata files; hence the spatial metadata elements are also missing. The Census Bureau is aware of this problem and is in the process of fixing this issue. These corrections will be reflected in subsequent releases of the TIGER/Line Shapefiles.  See the list below of areas missing SMID information in the metadata.

Windows XP users who are downloading multiple files at the same time from the 2009 TIGER/Line Shapefiles main download page who are also using the Windows extraction utility will be unable to unzip the files. The Census Bureau is looking into possible resolutions for this problem. In the interim, users can use one of the following options to work around this issue:

• Use a different extraction utility other than the default Windows utility to unzip the files (i.e. WinZip or another similar tool).
• Use the 2009 TIGER/Line Shapefiles main download page to download the files one at a time by clicking on the individual file names.
• Use the ftp site to download the files.

The feature names in the All Lines shapefile may not be consistent from one edge to the next along the extent of a road feature. The All Lines shapefile identifies the primary street name for an edge, however some primary names and alternate names have been flipped resulting in a primary feature name for one edge being identified as an alternate name on another. All feature names (featname.dbf), whether primary or alternate, can be related to the All Lines shapefile (edges.shp) by matching the TLIDs.

In the All Lines shapefile, the permanent face ID on the left of the edge (TFIDL) value or the permanent face ID on the right of the edge (TFIDR) value will be blank for edges on the outer boundary of a county and for edges on the outer boundary of the United States, Puerto Rico and the Island Areas. The TFID (either left or right side) that does not appear in the attribute table of the county file will appear in the adjacent county's attribute table. This may impact users who are creating layers and topologies from the All Lines Shapefiles.

The Hancock County, IL TIGER county road name directions appear to be switched for the entire county.  This problem was confirmed by the BOC Headquarter Geographers, Chicago Regional Office Geographers and Hancock County, IL officials.  Hancock County Road names are based on a Northing and Easting coordinate grid system.  County Roads with Northing directionals should have an East-West orientation and County Roads with Easting directionals should have a North-South orientation in Hancock County, IL.  The Hancock County Road name directionals are opposite in the MAFTIGER Database (MTDB).  Northing directionals have an incorrect North-South orientation and the Easting County Roads have an incorrect East-West orientation in Hancock County.  BOC Geography Division is aware of this problem and steps are being taken to resolve this problem.

The ZIP plus 4 code values will not appear in the 2009 TIGER/Line Shapefiles.

Both the Census 2000 5-Digit ZIP Code Tabulation Area (ZCTA5) Shapefile and the 2002 5-Digit ZIP Code Tabulation Area (ZCTA5) Shapefile will not contain values for areas without an actual ZCTA code. That is, areas with large amounts of land and no ZCTA code that were previously coded with nnnXX will not be included, and neither will areas with large amounts of water and no ZCTA code that were previously coded with nnnHH. As a result, there is no longer complete coverage of the United States and Puerto Rico by 5-digit ZCTAs, rather only those areas that have an actual ZCTA code will be included in the coverage. Also, the Topological Faces (2-cells with all Geocodes) Relationship File will not contain ZCTA5CE00 or ZCTA5CE codes where code is nnnXX or nnnHH. This means that only those faces that make up a ZCTA boundary will contain ZCTA codes.

Spatial data are incorrect for a number of elementary, secondary, and unified school districts where tiny overlaps and holes in school district coverage can be found.  These problems were corrected in the Census Bureau’s source database for the 2009 American Community Survey and the Population Estimates Program.  We have not identified wide-spread issues, but it is possible there are additional counties with overlaps or holes.  The state and county names, state and county FIPS codes, and school districts where this occurs are below:

Overlaps:
Windham, CT (09015)
elementary school district (ELSD) 00720 and unified school district (UNSD) 05190

Middlesex, MA (25017)
ELSD 03330, secondary school district (SCSD) 03870, and UNSD 03510

Worcester, MA (25027)
ELSD 02910, SCSD 02580, and UNSD 10770

Gaps:
Lee, AL (01081)
between UNSDs 02070 and 02700

Hall, GA (13139)
between UNSDs 02610 and 02310

Burlington, NJ (34005)
between ELSD 10950, SCSD 08480 and UNSD 10710

Shelby, TN (47157)
between UNSDs 02940 and 03810

Topological faces with the LWFLAG values: G (Glacier), I (Intermittent Water), L (Land) and S (Marsh/Swamp) are considered land areas for the calculation of the Areawater shapefile, ALAND measurement field.  Only topological faces with the LWFLAG value of P (Perennial Water) are used to calculate water areas in the Areawater shapefile, AWATER measurement field.  Glaciers, intermittent lakes, and marsh/swamp are considered water features although the area within them is classified as land for area measurement purposes.

The NAMELSAD field in the current American Indian/Alaska Native/Native Hawaiian shapefiles lists the name of the area with AIANNH code 3280 as “Sac and Fox/Meskwaki Ranch Reservation”.  This is incorrect; it should be “Sac and Fox/Meskwaki Settlement”.

The 2009 TIGER/Line Shapefiles contain an extract from the MAF/TIGER database as of May 2009 and includes three vintages of geography. See Chapter 4 of the technical documentation for a detailed description of each file type and vintage.

Current Census Geography
Current geography is defined as the latest version of the geographic extent of legally defined geographic areas as reported, generally reflecting the boundaries of governmental units in effect as of January 1, 2009, or legal and statistical area boundaries that have been adjusted and/or corrected since Census 2000. This vintage enables users to see the most current boundaries of governmental units and they will match the data from the surveys that use 2009 geography, such as the 2009 Population Estimates. The layer names may be followed by (Current) or have no name in parentheses.

Census 2000 Geography
Census 2000 geography is the geographic extent of legally defined geographic areas or statistical areas in effect on January 1, 2000. This vintage enables users to work with Census 2000 data using boundaries as they existed in 2000. Since 2000, the Census Bureau initiated significant operations to improve the coordinate accuracy of our geographic database-the MAF/TIGER Accuracy Improvement Project or MTAIP. The MTAIP modified the base coordinates of virtually all the features in the database, thus the representation of Census 2000 geography will not match the representation depicted in the Census 2000 TIGER/Line files. The inventory and attributes of the 2000 census geography is, however, unchanged. The layer names are followed by (Census 2000) and the files have an "00" at the end of their name.

2007 Economic Census Geography
2007 Economic Census geography is defined as the version of the geographic extent of legally defined geographic areas in effect on January 1, 2007. The Economic Census is the major economic statistical program of the United States, and it provides a detailed portrait of the nation’s economy once every five years. The geographic entities used in an Economic Census can differ from those used in decennial censuses. The boundaries used for geographic entities for the 2007 Economic Census are those reported to the Census Bureau through the Boundary and Annexation Survey (BAS) to be legally in effect on January 1, 2007. The layer names are followed by (Economic Census) and the files have an "ec" at the end of their name.

Updates from participant programs directly related to the 2010 Census are not reflected in the 2009 TIGER/Line Shapefiles. We were continuing to process updates and verify changes when this version of the TIGER/Line Shapefiles were produced to support 2009 geographic programs and surveys. These updates will be part of the 2010 Census TIGER/Line Shapefiles, which will be released to the public beginning in early 2011. The 2010 Census TIGER/Line Shapefiles will include updated geographic areas such as census blocks, census tracts, school districts, and voting districts.

In Appendix A of the technical documentation, the record layout for the Topological Faces (Polygons With All Geocodes) Shapefile is missing the following field:

This field should appear between CSAFP and METDIVFP.
