Abstract:Mapping Census 2000: The Geography of U.S. Diversity is an atlas containing 75 maps and presenting county- and state-level data for Census 2000. Cynthia Brewer and Trudy Suchan rapidly produced the atlas in the Population Division of the U.S. Census Bureau using ArcInfo 8.1 prerelease software. Redistricting data, on which the atlas was based, were released in March 2001 and the full-color atlas went to press in July 2001. It is the first decennial atlas produced by the Census Bureau in 80 years. Race maps in the atlas are designed to present the new Census 2000 data that include counts of people who indicated more than one race. Choropleth classifications are constructed to facilitate comparison among maps in series for all race/ethnicity groups, both large and small. Map series share breaks that are adjusted to include meaningful breaks based on overall U.S. percentages for individual groups. Additional shared meaningful breaks, such as "no change" and "50 percent of the population" also anchor classifications. Maps of prevalent groups and diversity provide syntheses of race/ethnicity data. Maps were evaluated at numerous levels in the Census Bureau, with issues from topic selection to page layout to title wording debated by many people. The essay describes the production processes, agency standards, and cartographic principles that come together to present these new data in an atlas that is a colorful showpiece.

- Cartography and Geographic Information Science (CaGIS) is the official publication of the Cartography and Geographic Information Society. CaGIS supports research, education, and practices that improve the understanding, creation, analysis, and use of maps and geographic information. The society serves as a forum for the exchange of original concepts, techniques, approaches, and experiences by those who design, implement, and use geospatial technologies through the publication of authoritative articles and international papers. The role of the CaGIS journal is to facilitate these objectives by disseminating results and reports in these areas of interest.
Cartography and Geographic Information Science (CaGIS) is now being published by Taylor & Francis as of 2013. Please visit the Journal's website at www.tandfonline.com/tcag or contact email@example.com to subscribe and obtain online access.
