  1. Title: U.S. Census Urban Areas, 2013

    Contributors:

    Summary: U.S. Census Urban Areas represents the 2010 Census urban areas in the United States. An urban area comprises a densely settled core of census tracts and/or census blocks that meet minimum population density requirements, along with adjacent territory containing non-residential urban land uses as well as territory with low population density included to link outlying densely settled territory with the densely settled core. To qualify as an urban area, the territory identified according to criteria must encompass at least 2,500 people, at least 1,500 of which reside outside institutional group quarters. The U.S. Census Bureau identifies two types of urban areas—Urbanized Areas (UA) of 50,000 or more people and Urban Clusters (UC) of at least 2,500 and less than 50,000 people. The U.S. Census Bureau delineates urban areas that represent densely developed territory, encompassing residential, commercial, and other non-residential urban land uses. In general, this territory consists of areas of high population density and urban land use resulting in a representation of the "urban footprint."

  10. Title: Census Block Groups, 2000 - San Francisco Bay Area, California

    Contributors:

    Summary: This polygon shapefile displays U.S. Census Block Groups for the San Francisco Bay Area in California as of January 1, 2000. Block Groups (BGs) are clusters of blocks within the same census tract having the same first digit of their 4-digit census block number. For example, block group 3 (BG 3) within a census tract includes all blocks numbered from 3000 to 3999. Census 2000 BGs generally contain between 600 and 3,000 people, with an optimum size of 1,500 people. Most BGs were delineated by local participants in the U.S. Census Bureau's Participant Statistical Areas Program. The U.S. Census Bureau delineated BGs only where a local or tribal government declined to participate or where the U.S. Census Bureau could not identify a potential local participant.A BG usually covers a contiguous area. Each census tract contains at least one BG and BGs are uniquely numbered within census tract. Within the standard census geographic hierarchy BGs never cross county or census tract boundaries, but may cross the boundaries of county subdivisions, places, urbanized areas, voting districts, congressional districts, and American Indian/Alaska Native areas/Hawaiian home lands. Under the Census 2000 American Indian/Alaska Native area/Hawaiian homeland census geographic hierarchy, census tracts and BGs are defined within American Indian entities and can cross state and county boundaries. These are commonly referred to as Tribal BGs.BGs have a valid range of 0 through 9. BGs beginning with a 0 generally are in coastal and Great Lakes water and territorial seas. Rather than extending a census tract boundary into the Great Lakes or out to the three mile territorial sea limit, the U.S. Census Bureau delineated some census tract boundaries along the shoreline or just offshore. The U.S. Census Bureau assigned a default census tract number of 0000 and BG of 0 to the offshore areas not included in regularly numbered census tract areas.In decennial census data tabulations, a block group may be split to present data for every unique combination of county subdivision, place, voting district, congressional district, American Indian area/Alaska Native area/ Hawaiian home land shown in the data tabulation products.

  13. Title: Census Blocks, 2000 - San Francisco Bay Area, California

    Contributors:

    Summary: The polygons in this data layer represent U.S. Census Blocks for the San Francisco Bay Area in California. These data have been clipped to the shoreline for cartographic representation. Census blocks are statistical areas bounded on all sides by visible features such as streets, roads, streams, and railroad tracks, and by invisible boundaries such as city, town, township, and county limits, and short imaginary extensions of streets and roads. Generally census blocks are small in area; for example, a block in a city bounded by streets. However, census blocks in remote areas may be large and irregular and contain hundreds of square miles. All territory in the United States, Puerto Rico, and the Island Areas have block numbers. Blocks are composed of one or more GT-polygons; that is, several GT-polygons can share the same block number. Census 2000 Block Numbers. Census 2000 tabulation blocks are numbered uniquely within each state/county/census tract with a four-digit census block number. The U.S. Census Bureau created the tabulation block numbers immediately before beginning its Census 2000 data tabulation process, thereby eliminating block suffixes. The first digit of the tabulation block number identifies the block group. For the 1990 census, the U.S. Census Bureau assigned a unique 1990 block number with a suffix of "Z" to identify crews-of-vessels population. For Census 2000, crews-of-vessels population is assigned to the land block identified by the U.S. Census Bureau as associated with the home port of the vessel. Water Blocks. The U.S. Census Bureau introduced a different method for identifying the water areas of census blocks for Census 2000. For the 1990 census, water was not uniquely identified within a census block; instead, all water area internal to a block group was given a single block number ending in "99" (for example, in block group 1, all water was identified as block 199). A suffix was added to each 1990 water block number where the block existed in more than one tabulation entity within its block group. For Census 2000, water area located completely within the boundary of a single land block has the same block number as that land block. Water area that touches more than one land block is assigned a unique block number not associated with any adjacent land block. The U.S. Census Bureau assigned water block numbers beginning with the block group number followed by "999 " and preceding in descending order. For example, in block group 3, the block numbers assigned to water areas that border multiple land blocks are 3999, 3998, 3997, and so forth. Because some land blocks include water (ponds and small lakes), no conclusions about whether or not a block is all land or all water can be made by looking at the Census 2000 block numbers. Data users must use the WATER field on Record Type S to determine if the GT-polygon is land or water. The WATER field has two values, 0 for land or 1 for water.

  14. Title: 2000 Census Traffic Analysis Zones - San Francisco Bay Area, California

    Contributors:

    Summary: This polygon shapefile contains the traffic analysis zones (TAZs) for the San Francisco Bay Area in California. These data have been clipped to the shoreline for cartographic representation. TAZs are special-purpose geographic entities delineated by state and local transportation officials for tabulating traffic related data from the decennial census, especially journey-to-work and place-of-work statistics. A TAZ usually consists of one or more census blocks, block groups, or census tracts. Each TAZ is identified by a 6-character alphanumeric census code that is unique within county or statistically equivalent entity. A code of ZZZZZZ indicates a portion of a county where no TAZs were defined. This layer is part of the Bay Area Metropolitan Transportation Commission (MTC) GIS Maps and Data collection.

  15. Title: Census Landmark Polygon Features, 2000 - San Francisco Bay Area, California

    Contributors:

    Summary: This polygon shapefile displays landmark features throughout the San Francisco Bay Area in California. "Landmark" is the general name given to a cartographic (or locational) landmark, a land-use area, and a key geographic location (KGL). A cartographic landmark is identified for use by an enumerator while working in the field. A land-use area is identified in order to minimize enumeration efforts in uninhabited areas or areas where human access is restricted. A key geographic location is identified in order to more accurately geocode and enumerate a place of work or residence. The predominant feature classes represented in this layer include airports or airfields, cemeteries, fraternities or sororities, state or local parks or forests, golf courses, lookout towers, educational and religious institutions. Other possible landmark features could include military installations, multi-household or transient quarters, custodial facilities, other types of transportation facilities or terminals, employment centers, open space and other special landmark designations for post offices, police stations and firehouses. The Census Bureau includes landmarks in the Census TIGER data base for locating special features and to help enumerators during field operations. The Census Bureau added landmark features on an as-needed-basis and made no attempt to ensure that all instances of a particular feature were included. The absence of a landmark does not mean that the living quarters, e.g., hospitals and group quarters associated with the landmark were excluded from the 1990 enumeration. A census feature class code (CFCC) is used to identify the most noticeable characteristic of a feature. The CFCC is applied only once to a chain or landmark with preference given to classifications that cover features that are visible to an observer and a part of the ground transportation network. Thus, a road that also is the boundary of a town would have a CFCC describing its road characteristics, not its boundary characteristics. The CFCC, as used in the TIGER/Line files, is a three-character code. The first character is a letter describing the feature class; the second character is a number describing the major category; and the third character is a number describing the minor category. Landmark (Feature Class D) is the general name given to a cartographic (or locational) landmark, a land-use area, and a key geographic location.

    Contributors:

    Summary: This polygon shapefile represents U.S. Census Blocks for the San Francisco Bay Area of California as of the year 2000. Census blocks are statistical areas bounded on all sides by visible features such as streets, roads, streams, and railroad tracks, and by invisible boundaries such as city, town, township, and county limits, and short imaginary extensions of streets and roads.

  18. Title: UA Census Places, 2000 - North Dakota

    Contributors:

    Summary: This datalayer displays the Census Places for the state based on the ground condition of January 1, 2000. Places, for the reporting of decennial census data, include census designated places, consolidated cities, and incorporated places. Each place is assigned a five-digit Federal Information Processing Standards (FIPS) code, based on the alphabetical order of the place name within each state. If place names are duplicated within a state, and they represent distinctly different areas, a separate code is assigned to each place name alphabetically by primary county in which each place is located, or if both places are in the same county, alphabetically by their legal description (for example, ''city'' before ''village''). Statistical entities which may be represented in this datalayer include: Census Designated Place (CDP). Census designated places (CDPs) are delineated for each decennial census as the statistical counterparts of incorporated places. CDPs are delineated to provide census data for concentrations of population, housing, and commercial structures that are identifiable by name but are not within an incorporated place. CDP boundaries usually are defined in cooperation with state, local, and tribal officials. These boundaries, which usually coincide with visible features or the boundary of an adjacent incorporated place or other legal entity boundary, have no legal status, nor do these places have officials elected to serve traditional municipal functions. CDP boundaries may change from one decennial census to the next with changes in the settlement pattern; a CDP with the same name as in an earlier census does not necessarily have the same boundary. Consolidated City. An incorporated place that has combined its governmental functions with a county or subcounty entity but contains one or more other incorporated places that continue to function as local governments within the consolidated government. Incorporated Place. A type of governmental unit, incorporated under state law as a city, town (except in New England, New York, and Wisconsin), borough (except in Alaska and New York), or village, having legally prescribed limits, powers, and functions.

  19. Title: UA Census Physical Features, 2000 - North Dakota

    Contributors:

    Summary: This datalayer represents tangible physical features throughout the state. These features are neither transportation nor hydrographic in nature but may be used to determine boundary lines. The predominant Feature Codes in this layer are: E00 (Physical feature, major and minor categories unknown); E20 (Topographic feature; major category used when the minor category could not be determined); and E21 (Ridge line, the line of highest elevation of a linear mountain). Additional features which may be identified in this, or other layers, include: Fences: Fence lines locate a visible and permanent fence between separately identified property. For example, a fence around a military reservation or prison separates the reservation from civilian land. Thus, a fence line is a property line marked by a fence. Topographic Feature:Topographical features that may be used as boundaries or as a reference for an area. The Census TIGER database contains topographic features used to define the limits of statistical entities in locations where no other visible feature can be identified. Other Topographic Feature: Mountain Peaks, Islands, (identified by name), levees, an embankment, as of earth or concrete, used to prevent a river or other body of water from overflowing.

  20. Title: UA Census County Subdivisions, 2000 - Rhode Island

    Contributors:

    Summary: This datalayer displays County Subdivisions (Minor Civil Divisions) for the state, based on legal and statistical entities established on January 1, 2000. County subdivisions are the primary divisions of counties and their statistical equivalents for the reporting of decennial census data. They include: Census County Divisions; Census Sub-areas; Minor Civil Divisions, and Unorganized Territories. The TIGER/Line files contain a 5-character numeric FIPS code field for county subdivisions. Legal Entities: Minor Civil Divisions (MCDs) MCDs are the primary governmental or administrative divisions of a county in many states. MCDs represent many different kinds of legal entities with a wide variety of governmental and/or administrative functions. MCDs are variously designated as American Indian reservations, assessment districts, boroughs, election districts, gores, grants, locations, magisterial districts, parish governing authority districts, plantations, precincts, purchases, road districts, supervisor's districts, towns, and townships. The U.S. Census Bureau recognizes MCDs in 28 states, Puerto Rico, and the Island Areas. The District of Columbia has no primary divisions, and the District of Columbia is considered equivalent to an MCD for statistical purposes. - In some states, all or some incorporated places are not part of any MCD. These places also serve as primary legal subdivisions and have a unique FIPS MCD code that is the same as the FIPS place code. The TIGER/ Line files will show the same FIPS 55 code in the county subdivision field and the place field. In other states, incorporated places are part of the MCDs in which they are located, or the pattern is mixed; some incorporated places are independent of MCDs and others are included within one or more MCDs. - The MCDs in 12 states (Connecticut, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Wisconsin) also serve as general-purpose local governments that generally can perform the same governmental functions as incorporated places. The U.S. Census Bureau presents data for these MCDs in all data products in which it provides data for places. - In New York and Maine, American Indian reservations (AIRs) exist outside the jurisdiction of any town (MCD) and thus also serve as the statistical equivalent of MCDs for purposes of data presentation. Statistical Entities: Census County Divisions (CCDs) CCDs are areas delineated by the U.S. Census Bureau, in cooperation with state officials and local officials for statistical purposes. CCDs have no legal function and are not governmental units. CCD boundaries usually follow visible features and in most cases, coincide with census tract boundaries. The name of each CCD is based on a place, county, or well-known local name that identifies its location. CCDs exist where: 1) There are no legally established minor civil divisions (MCDs). 2) The legally established MCDs do not have governmental or administrative purposes. 3) The boundaries of the MCDs change frequently. 4) The MCDs are not generally known to the public. Census Subareas Census subareas are statistical subdivisions of boroughs, city and boroughs, municipalities, and census areas, the statistical equivalent entities for counties in Alaska. The state of Alaska and the U.S. Census Bureau cooperatively delineate the census subareas to serve as the statistical equivalents of MCDs. Census subareas were first used in the 1980 census. Unorganized Territories (UTs) The U.S. Census Bureau defines unorganized territories in 10 minor civil division (MCD) states where portions of counties are not included in any legally established MCD or incorporated place. The U.S. Census Bureau recognizes such separate pieces of territory as one or more separate county subdivisions for census purposes. It assigns each unorganized territory a descriptive name, followed by the designation 'unorganized territory' and a county subdivision code. Unorganized territories were first reported in the 1960 census. The U.S. Census Bureau assigns a default county subdivision code of 00000 in some coastal and Great Lakes water where county subdivisions do not extend into the Great Lakes or out to the three-mile limit.
