TIGER/Line Shapefile, 2016, Series Information for the 2010 Census  Block State-based Shapefile

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 invisible 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.

School Districts are single-purpose administrative units within which local officials provide public educational services for the area's residents.  The Census Bureau obtains the boundaries, names, local education agency codes, grade ranges, and school district levels for school districts from State officials for the primary purpose of providing the U.S. Department of Education with estimates of the number of children in poverty within each school district.  This information serves as the basis for the Department of Education to determine the annual allocation of Title I funding to States and school districts.  


TIGER/Line Shapefiles include separate shapefiles for elementary, secondary and unified school districts. The school district boundaries are those in effect for the 2013-2014 school year.

Block Groups (BGs) are clusters of blocks within the same census tract. Each census tract contains at least one BG, and BGs are uniquely numbered within census tracts.  BGs have a valid code range of 0 through 9. BGs have the same first digit of their 4-digit census block number from the same decennial census.  For example, tabulation blocks numbered 5001, 5002, 5005,.., 5999 within census tract 1210.02 are also within BG 5 within that census tract.  BGs coded 0 are intended to only include water area, no land area, and they are generally in territorial seas, coastal water, and Great Lakes water areas. Block groups generally contain  between 600 and 5,000 people.  A BG usually covers a contiguous area but never crosses county or census tract boundaries. They may, however, cross the boundaries of other geographic entities like county subdivisions, places, urban areas, voting districts, congressional districts, and American Indian / Alaska Native / Native Hawaiian areas. 


The BG boundaries in this release are those that were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2010 Census.

Series Information for the 2019 Public Use Microdata Areas Shapefile, 1:500,000

The 2019 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files.
                
                After each decennial census, the Census Bureau delineates Public Use Microdata Areas (PUMAs) for the tabulation and dissemination of decennial census Public Use Microdata Sample (PUMS) data, American Community Survey (ACS) PUMS data, and ACS period estimates. Nesting within states, or equivalent entities, PUMAs cover the entirety of the United States, Puerto Rico, Guam, and the U.S. Virgin Islands. PUMA delineations are subject to population, building block geography, geographic nesting, and contiguity criteria. Each PUMA is identified by a 5-character numeric census code that may contain leading zeros and a descriptive name. Pumas are avialiable at the 1:500,000

The Census Bureau includes landmarks in the MTDB for locating special features and to help enumerators during field operations.  Some of the more common landmark types include area landmarks such as airports, cemeteries, parks, mountain peaks/summits, schools, and churches and other religious institutions.  The Census Bureau has added landmark features to MTDB on an as-needed basis and made no attempt to ensure that all instances of a particular feature were included.  The presence or absence of a landmark such as a hospital or prison does not mean that the living quarters associated with that landmark were geocoded to that census tabulation block or excluded from the census enumeration.

The Topological Faces / Area Landmark Relationship File (FACESAL.dbf) contains a record for each face / area landmark relationship.  Face refers to the areal (polygon) topological primitives that make up MTDB.  A face is bounded by one or more edges; its boundary includes only the edges that separate it from other faces, not any interior edges contained within the area of the face.  The face to which a record in the Topological Faces / Area Landmark Relationship File (FACESAL.dbf) applies can be determined by linking to the Topological Faces Shapefile (FACES.shp) on the permanent topological face identifier (TFID) attribute.  The area landmark to which a record in the Topological Faces / Area Landmark Relationship File (FACESAL.dbf) applies can be determined by linking to the Area Landmark Shapefile (AREALM.shp) on the area landmark identifier (AREAID) attribute.  A face may be part of multiple area landmarks.  An area landmark may consist of multiple faces.

State Legislative Districts (SLDs) are the areas from which members are elected to State legislatures. The SLDs embody the upper (senate) and lower (house) chambers of the state legislature. Nebraska has a unicameral legislature and the District of Columbia has a single council, both of which the Census Bureau treats as upper-chamber legislative areas for the purpose of data presentation; there are no data by SLDL for either Nebraska or the District of Columbia. A unique three-character census code, identified by State participants, is assigned to each SLD within a state. In Connecticut, Illinois, Louisiana, Maine, Maryland, Massachusetts, Michigan, Ohio, and Puerto Rico, the Redistricting Data Program (RDP) participant did not define the SLDs to cover all of the state or state equivalent area. In these areas with no SLDs defined, the code "ZZZ" has been assigned, which is treated as a single SLD for purposes of data presentation. 

 
The boundaries of the 2014 State legislative districts were provided by state-level participants through the RDP and reflect the districts used to elect members in or prior to the November 2014 election.

TIGER/Line Shapefile, 2015, Series Information for the Current Place State-based Shapefile

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.

               The TIGER/Line shapefiles include both incorporated places (legal entities) and census designated places or CDPs (statistical entities).  An incorporated
               place is established to provide governmental functions for a concentration of people as opposed to a minor civil division (MCD), which generally is
               created to provide services or administer an area without regard, necessarily, to population.  Places always nest within a state, but may extend across
               county and county subdivision boundaries.  An incorporated place usually is a city, town, village, or borough, but can have other legal descriptions.
               CDPs are delineated for the decennial census as the statistical counterparts of incorporated places.  CDPs are delineated to provide data for settled
               concentrations of population that are identifiable by name, but are not legally incorporated under the laws of the state in which they are located.  The
               boundaries for CDPs often are defined in partnership with state, local, and/or tribal officials and usually coincide with visible features or the
               boundary of an adjacent incorporated place or another legal entity.  CDP boundaries often change from one decennial census to the next with changes in
               the settlement pattern and development; a CDP with the same name as in an earlier census does not necessarily have the same boundary.  The only
               population/housing size requirement for CDPs is that they must contain some housing and population.  

               The boundaries of most incorporated places in this shapefile are as of January 1, 2013, as reported through the Census Bureau's Boundary and Annexation
               Survey (BAS).  Limited updates that occurred after January 1, 2013, such as newly incorporated places, are also included.  The boundaries of all CDPs
               were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2010 Census.
