THE DISTRICT AND UNIT VIEWS:  48 STATES
Regional Focus:  Districts and Units
In this section, individual District maps will be considered more closely along with maps showing units within districts.  The maps in this section were made in support of my work on national committees, for particular purposes.  Thus, assignment of district fragments, external to the body of the district, were made to any district which totally contained that fragment.  Similarly, unassigned territories were assigned to the district containing them and were given a "logical" unit number (with that logic based on adjacency patterns).  Such grouping was done merely for visual convenience in looking at district patterns.  The first map below shows all units within districts; only the districts are labelled.  In the table below, maps for a given district fill a single row.  There are 25 rows, one for each district. The first maps in the sequence show labelled units within district boundaries, based on ACBL ZIP code files.  The last map in the sequence, at the end of each column, shows the lack of fit between ZIP Code (yellow stripes) and County (red stripes) district boundaries for each district.

This Atlas of international, national, and regional bridge maps is designed for visualizing information about the broader bridge-playing population.  Selected problems are considered using the evidence of maps.  These maps are tied in the computer to various ACBL databases and U.S. Census databases.  Thanks to Jay Baum, ACBL CEO, Rick Beye, Carol Robertson, Richard Oshlag, and Ed Evers, ACBL, for providing the materials directly to Sandra Arlinghaus, who then created the map sets using GIS software (ESRI, ArcView 3.2) that forges a dynamic link between underlying database and outline base map.  Graphic adjusments of various kinds were made in Adobe PhotoShop or Adobe Illustrator.

The linked materials display data from the ACBL national data base.  If you are looking for local materials related to finding a bridge club, please go to maps created originally by Jim Lahey, former District 12 Webmaster, and maintained by Alan W. Bau, current District 12 Webmaster (http://www.d12bridge.org/).  If instead, you are looking for materials about the broader bridge-playing population, at the regional and national levels, you are in the right place!
