Abstract
This data represents Block Groups from the U.S. Census Bureau for Wisconsin in 2010. [The 2010 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 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.]
Purpose
This data is intended for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production, or to provide a basemap to support graphical overlays and analysis with other spatial data. [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.]
