TIGER/Line Shapefile, 2012, state, Montana, Current Block State-based
Dataset Identification:
Resource Abstract:
The TIGER/Line shapefiles and related database files (.dbf) 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 MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line
shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. 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. Census blocks are relatively small in area; for example, a block in a city bounded by streets. However, census
blocks in remote areas are often large and irregular and may even be many square miles in area. A common misunderstanding
is that data users think census blocks are used geographically to build all other census geographic areas, rather all other
census geographic areas are updated and then used as the primary constraints, along with roads and water features, to delineate
the tabulation blocks. As a result, all 2010 Census blocks nest within every other 2010 Census geographic area, so that Census
Bureau statistical data can be tabulated at the block level and aggregated up to the appropriate geographic areas. Census
blocks cover all territory in the United States, Puerto Rico, and the Island Areas (American Samoa, Guam, the Commonwealth
of the Northern Mariana Islands, and the U.S. Virgin Islands). 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.

ConceptualConsistency
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.
