The Register of Geographic Codes (RGC) is a key product that contains the definitive list of UK statistical geographies. ONS maintains the definitive set of statistical geographies, coordinates the issue of new codes, and maintains the relationship between active and archived code ranges on behalf of the Government Statistical Service. The RGC should be used in conjunction with the Code History Database, available to download separately.

This zip file contains the Code History Database for the United Kingdom as at December 2018. To download the zip file click the Download button. The Code History Database (CHD) contains the GSS nine-character codes, where allocated, for current and new statistical geographies from 1 January 2009. The codes consist of a simple alphanumeric structure; the first three characters (ANN) represent the area entity (i.e. type; or category of geography) and the following six characters (NNNNNN) represent the specific area instance. The CHD provides multiple functionality including details of codes, relationships, hierarchies and archived data. The CHD can be used in conjunction with the Register of Geographic Codes (RGC) that summarises the range of area instances within each geographic entity. The GSS Coding and Naming policy for some statistical geographies was implemented on 1 January 2011. From this date, where new codes have been allocated they should be used in all exchanges of statistics and published outputs that normally include codes.

This dataset identifies selected economic characteristics by zip code tabulation areas within the United States. This dataset resulted from the American Community Survey (ACS) conducted from 2010 through 2014. The economic characteristics include employment status, commuting to work, occupation, class of worker, income and benefits, health insurance coverage, and percentage of families and people whose income in the past 12 months is below the poverty level.

The 2005 First Edition TIGER/Line files are an extract of selected geographic and cartographic information from the Census TIGER database. The geographic coverage for a single TIGER/Line file is a county or statistical equivalent entity, with the coverage area based on the latest available governmental unit boundaries. The Census TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each county-based TIGER/Line file is designed to stand alone as an independent data set or the files can be combined to cover the whole Nation. The 2005 First Edition TIGER/Line files consist of line segments representing physical features and governmental and statistical boundaries. The files contain information distributed over a series of record types for the spatial objects of a county. There are 19 record types, including the basic data record, the shape coordinate points, and geographic codes that can be used with appropriate software to prepare maps. Other geographic information contained in the files includes attributes such as feature identifiers/census feature class codes (CFCC) used to differentiate feature types, address ranges and ZIP Codes, codes for legal and statistical entities, latitude/longitude coordinates of linear and point features, landmark point features, area landmarks, and area boundaries.

Tables containing standard codes for various geographic areas. The codes are described in greater detail in the VT Geographic Area Names and Codes Standard. The table preview shows 1 of the tables--the COMMCODE table. All tables and metadata are available for download via 1 .zip file; the .zip file contains the tables in Esri File Geodatabase format, DBF, CSV, and XLS.

This is an export from the PostgreSQL DBMS (v9.4.5 Win 64b) of the 2018 Official Geographic Code made available on 26/03/2018 by INSEE (UTF8 encoding). It is necessary to create the schema ref_insee_cog in the base of arrival before restoring the data. Genealogy: The eight tables of the COG 2018 in "TXT" format have their extension changed to "CSV"; the file is edited (Notepad++), the separator is modified (point-to-point tabulation) In the ref_insee_cog schema, the table structures are created in SQL (CREATE TABLE) with the addition at the end of the table of an internal identifier of type SERIAL for each table; these tables are commented (tables and attributes). The data is loaded into the PostgreSQL database from the CSV files from the PgAdmin interface (CSV, Win1252 encoding, semicolon with header); After import the type SERIAL is dropped for the type INTEGER (DROP SEQUENCE) The constraints are set (ALTER TABLE ADD CONSTRAINT): primary key, one or more constraints of semantic uniqueness, a foreign key for some tables. Some useful additional attributes have been created (ALTER TABLE ADD COLUMN): aurh_com_ide for the common code with 5 fixed characters, aurh_libgeo for a label formatted "Name proper" in one piece, then these attributes are calculated from native values (UPDATE... CASE WHEN) The eight country_2018, region_2018, dep_2018, arr_2018, can_2018, comsimp_2018, france_2018 and historiq_2018 tables of this schema ref_insee_cog are exported at the command line (pg_dump/pg_restore). Formatting Apart from the digital primary key no formatting was applied for country_2018, reg_2018 and dep_2018. Particular care must be taken to ensure that the department code is formatted on at least 2 characters (no digital transformation) For the district (q=332) a geographical code (VARCHAR 4) has been added as well as a wording (VARCHAR 48). A foreign key was applied to the department. For the canton (q=2054) a geographical code (VARCHAR 5) and geographical description (VARCHAR 48) have been added. A foreign key was applied to the department. NB: the canton does not have the district (sic). The value of the ‘burcentral’ field has been transformed into aurh_com_ide for the central municipality.

The Postal Code Conversion File (PCCF) is a digital file, which provides a correspondence between the six character postal code and Statistics Canada's standard geographical areas for which census data and other statistics are produced. Through the link between postal codes and standard geographic areas, the PCCF permits the integration of data from various sources. The Single Link Indicator provides one best link for every postal code, as there are multiple records for many postal codes. To obtain the postal code conversion file or for questions, consult the DLI contact at your educational institution. The geographic co-ordinates attached to each postal code on the PCCF are commonly used to map the distribution of data for spatial analysis (e.g., clients, activities). The location information is a powerful tool for marketing, planning, or research purposes. In April 1983, the Geography Division released the first version of the Postal Code Conversion File, which linked postal codes to census geographic areas and included geographic coordinates. Since then, the file has been updated on a regular basis to reflect postal code changes provided by Canada Post Corporation. Every five years, the postal code linkages on the PCCF are “converted” to the latest census geographic areas. The original PCCF was linked to the 1981 Census geographic areas. Since then, the PCCF has undergone three “conversions”, following the 1986, 1991 and 1996 censuses. An automated system was developed for the 1991-1996 conversion. Also, for the first time, the 1996 Census reported postal codes were used to validate the PCCF links.

The Geographic Feature Code Catalogue contains codes and definitions for geographic features captured and mapped by various BC Government Ministries, which are responsible for their definitions. These codes (fcodes) are embedded into geographic data to mark them, as an aid to integrating data from many sources. (WHSE_CORP.CORP_FEATURES)

This data set provides the capability of assigning geographic codes (State, county, and place) to records containing ZIP Code, post office name, and State Abbreviation. The file also contains spelling variations of post office names. The file was used by the Census Bureau in conjunction with other reference files to geocode responses from the 1982 Economic Censuses. This 1983 version has been updated to include codes for metropolitan statistical areas (MSA's) defined as of Dec. 31, 1983.< p>Fifty states, the District of Columbia, and Puerto Rico.

The geographic cross-reference files have been created to allow the user to prepare additional data summaries relevant to school districts. Another use for the geographic cross-reference files is to provide the ability to equate detailed record files having school district codes with census geographic units. This capability could be used to relate administrative record summaries with census geographic data. This data collection is the most current georeference file for the years 1973-1974. While it does not include all United States geography, it can be used to link district data with data available by other census areas. Variables include state, county, minor civil division (MCD), MCD-place, census tract, block group, enumeration district (ED), population of block group, school district code, school district type, percentage of population in school district, place description, congressional district, school district name, grade range, standard metropolitan statistical area (SMSA), and government ID code.
