TIGER/Line Shapefile, 2010, 2010 state, Texas, 2010 Census Block State-based Shapefile with Housing and Population Data
Dataset Identification:
Resource Abstract:
The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic
information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing
(MAF/TIGER) Database (MTDB). The purpose of this file is to provide the geography for the 2010 Census Blocks along with their
2010 housing unit count and population. Census Blocks are statistical areas bounded on all sides by visible features, such
as streets, roads, streams, and railroad tracks, and/or by nonvisible boundaries such as city, town, township, and county
limits, and short line-of-sight extensions of streets and roads. Blocks are the smallest geographic areas for which the Census
Bureau publishes data from the decennial census. A block may consist of one or more faces.

purpose:
In order for others to use the information in the Census MAF/TIGER database in a geographic information system (GIS) or for
other geographic applications, the Census Bureau releases to the public extracts of the database in the form of TIGER/Line
Shapefiles.

Use Constraints: The TIGER/Line Shapefile products are not copyrighted however TIGER/Line and Census TIGER are registered
trademarks of the U.S. Census Bureau. These products are free to use in a product or publication, however acknowledgment must
be given to the U.S. Census Bureau as the source. The boundary information in the TIGER/Line Shapefiles are for statistical
data collection and tabulation purposes only; their depiction and designation for statistical purposes does not constitute
a determination of jurisdictional authority or rights of ownership or entitlement and they are not legal land descriptions.
Coordinates in the TIGER/Line shapefiles have six implied decimal places, but the positional accuracy of these coordinates
is not as great as the six decimal places suggest.

Distribution Liability: No warranty, expressed or implied is made with regard to the accuracy of these data, and no liability
is assumed by the U.S. Government in general or the U.S. Census Bureau in specific as to the spatial or attribute accuracy
of the data. The act of distribution shall not constitute any such warranty and no responsibility is assumed by the U.S. government
in the use of these files. The boundary information in the TIGER/Line Shapefiles is for statistical data collection and tabulation

Technical Prerequisites: The TIGER/Line shapefiles contain geographic data only and do not include display mapping software
or statistical data. For information on how to use the TIGER/Line shapefile data with specific software package users shall
contact the company that produced the software.
description TIGER/Line Shapefiles are extracted from the Census MAF/TIGER database by nation, state, county, and entity. Census MAF/TIGER
data for all of the aforementioned geographic entities are then distributed among the shapefiles each containing attributes
for line, polygon, or landmark geographic data.

QuantitativeAttributeAccuracy
name Of Measure Attribute Accuracy
measure Description
Accurate against Federal Information Processing Standards (FIPS), FIPS Publication 6-4, and FIPS-55 at the 100% level for
the codes and base names. The remaining attribute information has been examined but has not been fully tested for accuracy.
Completeness Commission
Completeness Omission
evaluation Method Description
Data completeness of the TIGER/Line Shapefiles reflects the contents of the Census MAF/TIGER database at the time the TIGER/Line
Shapefiles were created.
ConceptualConsistency
name Of Measure Logical Consistency Report
measure Description
The Census Bureau performed automated tests to ensure logical consistency and limits of shapefiles. Segments making up the
outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. All polygons are tested for closure.
The Census Bureau uses its internally developed geographic update system to enhance and modify spatial and attribute data
in the Census MAF/TIGER database. Standard geographic codes, such as FIPS codes for states, counties, municipalities, county
subdivisions, places, American Indian/Alaska Native/Native Hawaiian areas, and congressional districts are used when encoding
spatial entities. The Census Bureau performed spatial data tests for logical consistency of the codes during the compilation
of the original Census MAF/TIGER database files. Most of the codes for geographic entities except states, counties, urban
areas, Core Based Statistical Areas (CBSAs), American Indian Areas (AIAs), and congressional districts were provided to the
Census Bureau by the USGS, the agency responsible for maintaining FIPS 55. Feature attribute information has been examined
but has not been fully tested for consistency. For the TIGER/Line Shapefiles, the Point and Vector Object Count for the G-polygon
SDTS Point and Vector Object Type reflects the number of records in the shapefile attribute table. For multi-polygon features,
only one attribute record exists for each multi-polygon rather than one attribute record per individual G-polygon component
of the multi-polygon feature. TIGER/Line Shapefile multi-polygons are an exception to the G-polygon object type classification.
Therefore, when multi-polygons exist in a shapefile, the object count will be less than the actual number of G-polygons.

FGDC-STD-001-1998 using the June 2011 version of the csdgm2iso19115-2_master.xslt stylesheet, which is based on NOAA's FGDC
CSDGM to ISO 19115-2 transform. This stylesheet has been modified for Census use by separating the stylesheets into various
sections. The Spatial Reference Information is not currently mapped over to ISO but will be mapped in future versions.
