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) System. The MAF/TIGER System 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 TIGERweb REST Services allows users to integrate the Census Bureau's Topologically Integrated Geographic Encoding and Referencing database (TIGER) data into their own GIS or custom web-based applications.For a more detailed description of the areas listed or terms below, refer to TIGER/Line documentation or the Geographic Areas Reference Manual, (GARM).This REST service contains Combined New England City and Town Area (CNECTA), Combined Statistical Area (CSA), Metropolitan Division, Core Based Statistical Areas (CBSA), and New England City and Town Area (NECTA) boundaries.Combined New England City and Town Areas (CNECTAs) consist of two or more adjacent NECTAs that have significant employment interchanges. The NECTAs that combine to create a CNECTA retain separate identities within the larger combined statistical areas.

Combined Statistical Areas (CSAs) consist of two or more adjacent CBSAs that have significant employment interchanges. The CBSAs that combine to create a CSA retain separate identities within the larger CSAs.

Metropolitan Divisions are smaller groupings of counties or equivalent entities within a metropolitan statistical area that contains a single core with 2.5 million inhabitants.

Core Based Statistical Area Codes (CBSA) are the metropolitan statistical areas, micropolitan statistical areas, NECTAs, metropolitan divisions, and NECTA divisions use a 5-character code. Each metropolitan statistical area must have one urbanized area of 50,000 or more inhabitants. Each micropolitan statistical area must have one urban cluster of 10,000 to 49,999 inhabitants.

New England City and Town Area (NECTA) Divisions are smaller groupings of cities and towns within a NECTA that contains a single core with 2.5 million inhabitants. A NECTA Division consists of a main city or town that represents an employment center, as well as adjacent cities and towns associated with the main city or town through commuting ties. Each NECTA Division must contain a total population of 100,000 or more.

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.

      Metropolitan and Micropolitan Statistical Areas are together termed Core Based Statistical Areas (CBSAs) and are defined by the Office of Management and
      Budget (OMB) and consist of the county or counties or equivalent entities associated with at least one urban core (urbanized area or urban cluster) of at
      least 10,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties
      with the counties containing the core. Categories of CBSAs are: Metropolitan Statistical Areas, based on urbanized areas of 50,000 or more population;
      and Micropolitan Statistical Areas, based on urban clusters of at least 10,000 population but less than 50,000 population. 

      The CBSAs boundaries are those defined by OMB based on the 2010 Census and published in 2013.

Telecommunications database targeted specifically toward disseminating all valid NPA/NXX combinations in the North American Numbering Plan. It covers all active North American NPA/NXX assignments. Included in the database are NPA (area code), NXX (exchange), country, state, county, latitude, longitude, LATA, time zone, day light saving, population, FIPS, MSA, PMSA, CBSA, ZIP code, Operating Company Number, use type, rate center, COMMON LANGUAGE identifier, and V&H.

This service offers Esri's Retail MarketPlace database for the United States which measures retail market supply and demand. The data is modeled from the Census of Retail Trade by the US Census Bureau, Infogroup business data, and statistics from the US Bureau of Labor Statistics.

All attributes are available at all geography levels: country, state, county, tract, block group, ZIP code, place, county subdivision, congressional district, core-based statistical area (CBSA), and designated market area (DMA).

Over 2,300 attributes measuring likely demand for a wide variety of products and services in retail categories including food and drink, automotive, electronics, appliances, health, and personal care. The database provides a direct comparison between retail sales and consumer spending by industry and measures the gap between supply and demand.

The School District Geographic Relationship Files (GRF) were designed to provide a complete set of geographic associations between school districts and other types of geographic areas including counties, Core Based Statistical Areas (CBSA), Consolidated Statistical Areas (CSA), New England City and Town Areas (NECTA), Zip Code Tabulation Areas (ZCTA), Urban Areas, Congressional Districts (CD), places, Census tracts, and Census block groups. The GRFs are based on the Census Bureau’s TIGER/Line database, and the tables provide a separate record for each part of a district that is uniquely associated with one of the other geographic areas.

Esri's Crime Indexes data incorporates information from the AGS national CrimeRisk database that is based on an extensive analysis of several years of crime incidents reported by most US law enforcement jurisdictions. The Crime Indexes database includes standardized indexes for a range of serious crimes against both persons and property. The data vintage is 2019. All attributes are available at the following geography levels: State, County, Tract, Block Group, ZIP Code, Place, CBSA and DMA. Attributes include total crime index, personal crime index, and other indexes for serious crimes.
