Attribute_Accuracy:
Attribute_Accuracy_Report:
Relied on the integrity of the attribute information within the original data layer.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
An urbanized area (UA) consists of densely settled territory that contains 50,000 or more people. A UA may contain both place and nonplace territory. The U.S. Census Bureau delineates UAs to provide a better separation of urban and rural territory, population, and housing in the vicinity of large places. At least 35,000 people in a UA must live in an area that is not part of a military reservation.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
For Census 2000, UA delineations constitute a "zero-based" approach that requires no "grandfathering" of UA boundaries from the 1990 census. Because of the more stringent density requirements (and the less restrictive extended place criteria), some territory that was classified as urbanized for the 1990 census has been reclassified as rural. In addition, some areas that were identified as UAs for the 1990 census have been reclassified as urban clusters.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
The title of a UA may contain up to three incorporated place names, and will include the two-letter U.S. Postal Service abbreviation for each state into which the UA extends. However, if the UA does not contain an incorporated place, the UA title will include the single name of the geographic entity that occurs first from the following list: census designated place, minor civil division, or populated place recognized by the U.S. Geological Survey.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
Each UA is assigned a five-digit census code in alphabetical sequence on a nationwide basis, interspersed with the codes for urban clusters (UCs), also in alphabetical sequence. For the 1990 census, the U.S. Census Bureau assigned a four-digit UA code based on the MA codes. For Census 2000, a separate flag is included in data tabulation files to differentiate between UAs and UCs. In printed reports, this differentiation is included in the name.

Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
Certain scale datasets are not suitable for some project, analysis, or modelling purposes. Please be sure you are using the best available data.

1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:250000 scale datasets are recommended for projects that are at the regional or state level or larger.

Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our web pages at:

Process_Description:
Data was downloaded in shapefile format by the GeoPlan Center 2002 from the UA/UC Census 2000 Boundary file website at: <http://www.census.gov/geo/www/ua/ua_bdfile.html>. When received, data was in Geographic projection, Datum: NAD83, Spheroid: GRS1980, Units: Decimal degrees. The data was queried to the State of Florida, reprojected to FGDL Albers HPGN, name was changed from "geo_2000_d_dec_00000_py_z1" to "ua2000", added items: POPULATION, POPDENSITY, AREA, and DESCRIPT, and all character items were upcased. Items P0PULATION, POPDENSITY, and AREA were all added from the associated Census documentation found at <http://www.census.gov/geo/www/tiger/tigerua/ua_tgr2k.html>
Process_Date: 2002
Process_Step:
Process_Description:
GeoPlan, during the QA/QC process included the following aspects: (1) Reprojected data to FGDL Albers HPGN (See "Map Projection Parameters" below) (2) Upcased all character records (3) Changed original name from "geo_2000_d_dec_00000_py_z1" to "ua2000" (4) Added items: POPULATION, POPDENSITY, and AREA (5) DESCRIPT item was added based on the item NAME
