A table entitled "Census Block Group Demographics Summary File 1 (SF1)" was also downloaded from the ESRI site, and then merged with the shapefiles in ArcMap.
"The Census 2000 TIGER/Line shapefiles were created from the Topologically Integrated Geographic Encoding and Referencing (TIGER) database of the United States Census Bureau.
The shapefiles contain data about the following features:
Line Features—roads, railroads, hydrography, and transportation and utility lines.
Boundary Features—statistical (e.g., census tracts and blocks); government (e.g., places and counties); and administrative (e.g., congressional and school districts).
Landmark Features—point (e.g., schools and churches); area (e.g., parks and cemeteries); and key geographic locations (e.g., apartment buildings and factories).
The shapefiles do not contain:
Zip Code Tabulation Areas (ZCTAs).
Current address range information as reflected in the Master Address File (MAF).
Corrections to naming of some geographic entities, including voting districts and school districts, and attributes such as Place Description Codes (PLACEDC) and Legal/Statistical Area Description Codes (LSADC).
This updated Census information for the 2000 TIGER/Line files is available from the U.S. Census Bureau at the following web site url: <http://www.census.gov/geo/www/tiger/tiger2k/tgr2000.html> The U.S. Census Bureau also provides GENERALIZED cartographic boundary files for many of their geographies. These cartographic boundary files can be downloaded by state, in shapefile format (.shp), as well as ArcInfo export files (.e00)."

"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."
The following is excerpted from the 634 page Web document produced by the U.S. Census Bureau pertaining to Census Block Group Demographics Summary File 1 (SF1), (<http://www.census.gov/prod/cen2000/doc/sf1.pdf>):
"Summary File 1 (SF 1) contains the 100-percent data, which is the information compiled from the questions asked of all people and about every housing unit. Population items include sex, age, race, Hispanic or Latino, household relationship, and group quarters. Housing items include occupancy status, vacancy status, and tenure (owner occupied or renter occupied).
There is a total of 171 population tables (identified with a ‘‘P’’) and 56 housing tables (identified with an ‘‘H’’) shown down to the block level, and 59 population tables shown down to the census tract level (identified with a ‘‘PCT’’) for a total of 286 tables. There are 14 population tables and 4 housing tables shown down to the block level, and 4 population tables shown down to the census tract level that are repeated by major race and Hispanic or Latino groups2.
SF 1 includes population and housing characteristics for the total population, population totals for an extensive list of race (American Indian and Alaska Native tribes, Asian, and Native Hawaiian and Other Pacific Islander) and Hispanic or Latino groups, and population and housing characteristics for a limited list of race and Hispanic or Latino groups. Population and housing items may be cross tabulated. Selected aggregates and medians also are provided. A complete listing of subjects in this file is found in the section, 'Subject Locator.'"
"The feature network of lines (as represented by Record Types 1 and 2) is compete for census purposes. Spatial objects in TIGER/Line belong to the "Geometry and Topology" (GT) class of objects in the "Spatial Data Transfer Standard" (SDTS) FIPS Publication 173 and are topologically valid. Node/geometry and topology (GT)-polygon/chain relationships are collected or generated to satisfy topological edit requirements. These requirements include:
* Complete chains must begin and end at nodes.
* Complete chains must connect to each other at nodes.
* Complete chains do not extend through nodes.
* Left and right GT-polygons are defined for each complete chain element and are consistent throughout the extract process.
* the chains representing the limits of the files are free of gaps.
The Census Bureau performed automated tests to ensure logical consistency and limits of files. 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 TIGER data base. Standard geographic codes, such as FIPS codes for states, counties, municipalities, and places, 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 TIGER data base files. Most of the Codes themselves 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."
"Data completeness of the TIGER/Line files reflects the contents of the Census TIGER data base at the time the TIGER/Line files (Redistricting Census 2000 version) were created."
"The information present in these files is provided for the purposes of statistical analysis and census operations only. Coordinates in the TIGER/Line files have six implied decimal places, but the positional accuracy of these coordinates is not as great as the six decimal places suggest. The positional accuracy varies with the source materials used, but generally the information is no better than the established national map Accuracy standards for 1:100,000-scale maps from the U.S. Geological Survey (USGS); thus it is NOT suitable for high-precision measurement applications such as engineering problems, property transfers, or other uses that might require highly accurate measurements of the earth's surface. The USGS 1:100,000-scale maps met national map accuracy standards and use coordinates defined by the North American Datum, 1983. For the contiguous 48 States, the cartographic fidelity of most of the Redistricting Census 2000 TIGER/Line files, in areas outside the 1980 census Geographic Base File/Dual Independent map Encoding (GBF/DIME) file coverage and selected other large metropolitan areas, compare favorable with the USGS 1:100,000-scale maps. The Census Bureau cannot specify the accuracy of features inside of what was the 1980 GBF/DIME-File coverage or selected metropolitan areas. The Census Bureau added updates to the TIGER/Line files that enumerators annotated on maps sheets prepared from the Census TIGER data base as they attempted to traverse every street feature shown on the Census 2000 map sheets; the Census Bureau also made other corrections from updated map sheets supplied by local participants for Census Bureau programs. The locational accuracy of these updates is of unknown quality. In addition to the Federal, State, and local sources, portions of the files may contain information obtained in part from maps and other materials prepared by private companies. Despite the fact the TIGER/Line data positional accuracy is not as high as the coordinate values imply, the six-decimal place precision is useful when producing maps. The precision allows features that are next to each other on the ground to be placed in the correct position, on the map, relative to each other, without overlap."
ESRI ArcToolBox was used to merge the 92 shapefiles into one shapefile for Indiana. ESRI ArcToolBox "Define Projection Wizard" was then used to define the projection provided, which was Geographic (Decimal Degrees) NAD83. ESRI ArcToolBox "Project Wizard" was then used to reproject to UTM Zone 16, NAD83, and the output shapefile was named CENSUS_BLOCKS_TIGER00_IN.SHP. ESRI ArcMap was then used to merge the shapefile with the SF1 data table and was saved as CENSUS_BLOCKS_TIGER00_IN.SHP again.
"The TIGER/Line files contain data describing three major types of features/entities;
Line Features -
1) Roads
2) Railroads
3) Hydrography
4) Miscellaneous transportation features and selected power lines and pipe lines
5) Political and statistical boundaries
Landmark Features -
1) Point landmarks, e.g., schools and churches.
2) Area landmarks, e.g., Parks and cemeteries.
3) Key geographic locations (KGLs), e.g., shopping centers and factories.
Polygon features -
1) Geographic entity codes for areas used to tabulate the Census 2000 census statistical data and 1990 geographic areas
2) Locations of area landmarks
3) Locations of KGLs
The line features and polygon information form the majority of data in the TIGER/Line files. Some of the data/attributes describing the lines include coordinates, feature identifiers (names), CFCCs (used to identify the most noticeable characteristic of a feature), address ranges, and geographic entity codes. The TIGER/Line files contain point and area labels that describe landmark features and provide locational reference. Area landmarks consist of a feature name or label and feature type assigned to a polygon or group of polygons. Landmarks may overlap or refer to the same set of polygons. The Census TIGER data base uses collections of spatial objects (points, lines, and polygons) to model or describe real-world geography. The Census Bureau uses these spatial objects to represent features such as streets, rivers, and political boundaries and assigns attributes to these features to identify and describe specific features such as the 500 block of Market Street in Philadelphia, Pennsylvania."
