Series Information File for the 2012 Cartographic Boundary File, 2010 Census Urban Area, 1:500,000 2012 publication mapDigital The 2012 cartographic boundary shapefiles are simplified representations of selected geographic areas from the Census Bureau's MAF/TIGER geographic database. These boundary files are specifically designed for small-scale thematic mapping. When possible generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based shapefiles while others are available only as state-based files. To improve the appearance of shapes at small scales, areas are represented with fewer vertices than detailed TIGER/Line equivalents. These boundary files take up less disk space than their ungeneralized counterparts. Cartographic boundary files take less time to render on screen. These files were specifically created to support small-scale thematic mapping. completed notPlanned None planned. New cartographic boundary files will be produced on an annual release schedule. Types of geography released may vary from year to year. 2012 Cartographic Boundary Generalized Shapefile Urban Area Boundaries theme None US United States place None otherRestrictions Access Constraints: None Use Constraints: These products are free to use in a product or publication, however acknowledgement must be given to the U.S. Census Bureau as the source. The boundary information is for visual display at appropriate small scales only. Cartographic boundary files should not be used for geographic analysis including area or perimeter calculation. Files should not be used for geocoding addresses. Files should not be used for determining precise geographic area relationships. Distribution Liability: No warranty, expressed or implied is made with regard to the accuracy of these data, and no liability is assumed by the U.S. Government in general or the U.S. Census Bureau in specific as to the spatial or attribute accuracy of the data. The act of distribution shall not constitute any such warranty and no responsibility is assumed by the U.S. government in the use of these files. The boundary information is for small-scale mapping purposes only; boundary depiction and designation for small-scale mapping purposes do not constitute a determination of jurisdictional authority or rights of ownership or entitlement and they are not legal land descriptions. eng boundaries Technical Prerequisites: The cartographic boundary files contain geographic data only and do not include display or mapping software or statistical data. The files are delivered as zipped ESRI Shapefiles.

See the U.S. Census Bureau Geographic Terms and Concepts documentation for further explanation of Census geography (http://www.census.gov/geo/www/2010census/GTC_10.pdf). Below is a list of possible fields. Attribution will vary depending on the type of geography. Field names, descriptions and data types are listed in this format: FIELD_NAME Description [data value or type]. AFFGEOID AFF Summary Level Code, nation identifier; nation FIPS code [string]; AFFGEOID10 2010 Census AFF Summary Level Code, nation identifier; nation FIPS code [string]; ALAND Current land area [number]; ALAND10 2010 Census land area [number]; CD113FP 113th congressional district FIPS code [string]; CDSESSN 113th congressional session code [string]; GEOID identifier, code [string]; GEOID10 2010 Census identifier, 2010 Census code [string]; LSAD Current name and the translated legal/statistical area description code [string]; LSAD10 2010 Census name and the translated legal/statistical area description code [string]; LSY Legislative session year [string]; NAME10 2010 Census name [string]; NAMELSAD Current name and the translated legal/statistical area description [string]; NAMELSAD10 2010 Census name and the translated legal/statistical area description [string]; SLDLST Current state legislative district lower chamber code [string]; SLDUST Current state legislative district upper chamber code [string]; STATEFP Current state FIPS code [string]; UACE10 2010 Census urban area code [string]; UATYP10 2010 Census urban area type [string]. The ALAND or ALAND10 field is the calculated area derived from the ungeneralized area of each entity in square miles. This field can be used in density calculations. Users should not calculate the area of the generalized polygons for use in any analysis. Use the GEOID field to join these spatial tables to 2010 Census data tables if needed. Some nation-based files may include Puerto Rico and the Island Areas of the United States. Island areas include American Samoa, Guam, the Commonwealth of the Northern Mariana Islands (Northern Mariana Islands), and the United States Virgin Islands.

This stylesheet has been modified for Census use by separating the stylesheets into various sections. The Spatial Reference Information is not currently mapped over to ISO but will be mapped in future versions.
