2020 TIGER FilesTopologically Integrated Geographic Encoding and Referencing (TIGER) files are a product of the U.S. Census Bureau. These files include vector data on features such as transportation and hydrography, landmarks, Congressional Districts, and census blocks and tracts.Full technical documentation for TIGER/Line® Shapefiles can be found here.2020 Redistricting DataPublic Law (P.L.) 94-171, enacted by Congress in December 1975, requires the Census Bureau to provide states the opportunity to identify the small area geography for which they need data in order to conduct legislative redistricting. The law also requires the U.S. Census Bureau to furnish tabulations of population to each state, including for those small areas the states have identified, within one year of Census day.Since the first Census Redistricting Data Program, conducted as part of the 1980 census, the U.S. Census Bureau has included summaries for the major race groups specified by the Statistical Programs and Standards Office of the U.S. Office of Management and Budget (OMB) in Directive 15 (as issued in 1977 and revised in 1997). Originally, the tabulation groups included White, Black, American Indian/Alaska Native, and Asian/Pacific Islander, plus “some other race.” These race data were also cross-tabulated by Hispanic/Non-Hispanic origin. At the request of the state legislatures and the Department of Justice, for the 1990 Census Redistricting Data Program, voting age (18 years old and over) was added to the cross-tabulation of race and Hispanic origin. For the 2000 Census, these categories were revised to the current categories used today.To view the full technical documentation for the 2020 Census Redistricting Data, please click here.

TIGERweb allows the viewing of TIGER spatial data online and for TIGER data to be streamed to your mapping application. The web-based application allows the users to visualize our TIGER(Topologically Integrated Geographic Encoding and Referencing database) data. The application allows users to select features and view their attributes, to search for features by name or geocode, and to identify features by selecting them from a map. The TIGERweb application is a simple way to view our TIGER data without having to download the data. The web Mapping serivices provide a simple HTTP interface for requesting geo-registered map images from our geospatial database. It allows users to produce maps containg TIGERweb layers with layers from other servers.It consists of the following two applications and six services: Applications: TIGERweb TIGERweb2010 Services: Current Geography ACS 2012 ACS 2011 Census 2010 (for the TIGERweb application) Physical Features Census 2010 for the TIGERweb2010 application)

The intended dual purpose of MassGIS’ efforts in processing this data is to both create a geocoding resource that can supplement the addressing data available in its Master Address Database, and compile a comprehensive set of Census Bureau road features for map display, query, and analysis. Linear road features attributed with street names, address ranges, and other useful information have been generated from a combination of Census Bureau layers. A full list of the various Census 2020 TIGER/Line layers available for download can be found in this summary. See the datalayer metadata for full details.Map service also available.

The 2020 TIGER/Line Shapefiles contain current geographic extent and boundaries of both legal and statistical entities (which have no governmental standing) for the United States, the District of Columbia, Puerto Rico, and the Island areas. This vintage includes boundaries of governmental units that match the data from the surveys that use 2020 geography (e.g., 2020 Population Estimates and the 2020 American Community Survey). In addition to geographic boundaries, the 2020 TIGER/Line Shapefiles also include geographic feature shapefiles and relationship files. Feature shapefiles represent the point, line and polygon features in the MTDB (e.g., roads and rivers). Relationship files contain additional attribute information users can join to the shapefiles. Both the feature shapefiles and relationship files reflect updates made in the database through September 2020. To see how the geographic entities, relate to one another, please see our geographic hierarchy diagrams here.Census Urbanized Areashttps://www2.census.gov/geo/tiger/TIGER2020/UACCensus Urban/Rural Census Block Shapefileshttps://www.census.gov/cgi-bin/geo/shapefiles/index.php2020 TIGER/Line and Redistricting shapefiles:https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.2020.htmlTechnical documentation:https://www2.census.gov/geo/pdfs/maps-data/data/tiger/tgrshp2020/TGRSHP2020_TechDoc.pdfTIGERweb REST Services:https://tigerweb.geo.census.gov/tigerwebmain/TIGERweb_restmapservice.htmlTIGERweb WMS Services:https://tigerweb.geo.census.gov/tigerwebmain/TIGERweb_wms.htmlThe legal entities included in these shapefiles are:American Indian Off-Reservation Trust LandsAmerican Indian Reservations – FederalAmerican Indian Reservations – StateAmerican Indian Tribal Subdivisions (within legal American Indian areas)Alaska Native Regional CorporationsCongressional Districts – 116th CongressConsolidated CitiesCounties and Equivalent Entities (except census areas in Alaska)Estates (US Virgin Islands only)Hawaiian Home LandsIncorporated PlacesMinor Civil DivisionsSchool Districts – ElementarySchool Districts – SecondarySchool Districts – UnifiedStates and Equivalent EntitiesState Legislative Districts – UpperState Legislative Districts – LowerSubminor Civil Divisions (Subbarrios in Puerto Rico)The statistical entities included in these shapefiles are:Alaska Native Village Statistical AreasAmerican Indian/Alaska Native Statistical AreasAmerican Indian Tribal Subdivisions (within Oklahoma Tribal Statistical Areas)Block Groups3-5Census AreasCensus BlocksCensus County Divisions (Census Subareas in Alaska)Unorganized Territories (statistical county subdivisions)Census Designated Places (CDPs)Census TractsCombined New England City and Town AreasCombined Statistical AreasMetropolitan and Micropolitan Statistical Areas and related statistical areasMetropolitan DivisionsNew England City and Town AreasNew England City and Town Area DivisionsOklahoma Tribal Statistical AreasPublic Use Microdata Areas (PUMAs)State Designated Tribal Statistical AreasTribal Designated Statistical AreasUrban AreasZIP Code Tabulation Areas (ZCTAs)Shapefiles - Features:Address Range-FeatureAll Lines (called Edges)All RoadsArea HydrographyArea LandmarkCoastlineLinear HydrographyMilitary InstallationPoint LandmarkPrimary RoadsPrimary and Secondary RoadsTopological Faces (polygons with all geocodes)Relationship Files:Address Range-Feature NameAddress RangesFeature NamesTopological Faces – Area LandmarkTopological Faces – Area HydrographyTopological Faces – Military Installations

This resource is a member of a series. 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. County subdivisions are the primary divisions of counties and their equivalent entities for the reporting of Census Bureau data. They include legally-recognized minor civil divisions (MCDs) and statistical census county divisions (CCDs), and unorganized territories. For the 2010 Census, the MCDs are the primary governmental and/or administrative divisions of counties in 29 States and Puerto Rico; Tennessee changed from having CCDs for Census 2000 to having MCDs for the 2010 Census. In MCD States where no MCD exists or is not defined, the Census Bureau creates statistical unorganized territories to complete coverage. The entire area of the United States, Puerto Rico, and the Island Areas are covered by county subdivisions. The boundaries of most legal MCDs are as of January 1, 2023, as reported through the Census Bureau's Boundary and Annexation Survey (BAS). The boundaries of all CCDs are those as reported as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2020 Census.

The TIGERweb application allows users to access and view geospatial features, geographic area information, and associated attributes from the U.S. Census Bureau Topologically Integrated Geographic Encoding and Referencing System (TIGER) geodatabase. The TIGERweb application is intended to meet the needs of users inside and outside the Census Bureau for access to geospatial data contained within the TIGER geodatabase without requiring the use of a GIS. The TIGERweb map layers are grouped by the following geographies: Transportation (Roads and Railroads) PUMAs, UGAs, and ZCTAs Tribal Census Tracts and Block Groups Census Tracts and Blocks Military and other Special Land Use Areas School Districts Places and County Subdivisions American Indian, Alaska Native, and Native Hawaiian Areas Legislative Areas Census Regions and Divisions Urban Areas Metropolitan and Micropolitan Statistical Areas and Related Statistical Areas Hydrography States and Counties Labels are included for the map layers. These layers contains the latest version of legally defined areas reported to the Census Bureau and reflect the governmental units in effect as of January 1, 2014 or legal or statistical boundaries that have adjusted or corrected since the 2010 Census. Physical features like hydrography, transportation and special land use areas like military reservations reflect updates as of September 2014. In addition to the January 1, 2016 vintage (ACS 2016), the TIGERweb application also contains data as of January 1, 2015 (ACS 2015), and data as of January 1, 2010 (2010 Census). This application contains four vintages of data. Current And ACS 2016 both contain data from January 1, 2016. ACS 2015 contains data from January 1, 2015 vintage The Census 2010 consists of data as of January 1, 2010.

TIGERweb allows the viewing of TIGER spatial data online and for TIGER data to be streamed to your mapping application. TIGERweb consists of a web mapping service and a REST service.

This CD consists of the TIGER/Line Census Files, 1990. The type of File is geographic. The 1990 Census TIGER/Line file is an extract of selected geographic and cartographic information from the Census Bureau's TIGER data base. The Census Bureau is releasing the 1990 Census TIGER/Line files to provide data users with the final 1990 census boundaries (including voting districts) and to support the 1990 Census Data Products Program. The 1990 Census TIGER/Line file provides digital data for all 1 990 census map features and boundaries, the associated 1990 census final tabulation geographic area codes (such as 1990 census block numbers), and the codes for the January 1, 1990 legal and statistical areas on both sides of each line segment of every mapped feature. This version also contains the final voting district codes and the 1990 census designated place codes. The 1990 Census TIGER/Line file contains basic information for 1990 census geographic area codes, basic map features and their names, and address ranges in the form of 12 'Record Types.' The record types are as follows: 1. Basic Data Records (Individual Feature Segment Records) 2. Shape Coordinate Points (Feature Shape Records) 3. Additional Decennial Census Geographic Area Codes 4. Index to Alternate Feature Names 5. Feature Name List 6. Additional Address Range and ZIP Code(2) Information 7. Landmark Features 8. Area Landmarks A. Additional Polygon Geographic Area Codes I.

This shows the boundaries for American Indian reservations, counties, tracts, block groups, blocks, military boundaries and political townships as of 2020. TIGER/Line shapefiles downloaded directly from the U.S. Census at 2020 TIGER/Line ShapefilesThe 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 primary legal divisions of most states are termed counties. In Louisiana, these divisions are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs, municipalities, and for the unorganized area, census areas. The latter are delineated cooperatively for statistical purposes by the State of Alaska and the Census Bureau. In four states (Maryland, Missouri, Nevada, and Virginia), there are one or more incorporated places that are independent of any county organization and thus constitute primary divisions of their states. These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation.The full Kansas geospatial catalog is administered by the Kansas Data Access & Support Center (DASC) and can be found at the following URL: https://hub.kansasgis.org/

CDFW BIOS GIS Dataset, Contact: U.S. Fish & Wildlife Service USFWS, Description: These data identify, in general, the areas where final critical habitat for California tiger salamander, Central population, occur. The purpose is to provide the user with a general idea of areas where final critical habitat for California tiger salamander, Central population, occur.

A world without tigers is hard to imagine, but red flags are being hoisted across the tiger’s range. In Indochina, widespread poaching of tigers and wildlife continues to create empty forests, and the development of the proposed transnational economic corridors in the region will further fragment Indochina’s remaining forests and create dispersal barriers. In Sumatra and Malaysia, vast oil palm and acacia plantations are predicted to result in complete conversion of some of the richest lowland rain forests on Earth, habitats that were populated by tigers only a few years ago. The increasing demand for tiger parts for folk medicines in China and Southeast Asia and for costume adornment among Tibet’s growing middle-class has intensified threats to tigers across the range.But large mammals, including tigers, have coexisted for centuries with dense human populations. The release of the 1997 Tiger Conservation Unit Analysis identified where tigers can live in the future. During the decade since, experiences from implementing field conservation projects have confirmed that the future of wildlife conservation in Asia depends on judicious land use planning—zoning—of human use areas, core wildlife habitat, buffer zones, and corridors in large conservation landscapes to restore the harmony that once existed in the wild land-village interface of rural Asia.Learn more about the analysis and resultsThe User's Guide that highlights the remaining tiger lands—the large landscapes of habitat, often anchored by protected areas that are global priorities for conservation.The Technical Assessment: Setting Priorities for the Conservation and Recovery of Wild Tigers: 2005-2015The fate of wild tigers.
