We geocoded the Bernard Madoff client list (13,562 addresses) using the CommunityViewer GIS (CV), created a shapefile, and developed a CV project to examine the client distribution. The following views show locations/patterns of the clients. This section illustrates how a basic address list can be converted into a visual/geographic depiction. We have integrated the client list point shapefile with the New York County streets shapefile developed using the CV Edge2Shape feature. Some points approximate due to incomplete addresses or PO Box only.

Census 2010 will be conducted on April 1, 2010, just a little more than a year away. The Census Bureau American Community Survey (ACS) is now integrally linked with Census 2010. The "Census 2010/ACS" DMINews section provides monthly highlights of current and pending developments regarding these programs. The focus is on data access and use and to a lesser extent data development and related operations. Proximity will continue to maintain the decennial census focused Web pages Census 2000 and Census 2010.
Census must report redistricting data to states by April 1, 2011. Complete count tabulations and sample-based estimates will become available on a flow basis possibly extending into 2013. Block group level estimates may be available by 2012. One of the most valuable products of the decennial census is the cartographic data enabling wide-ranging geospatial analyses often independent of using the decennial census demographic data.

Annual U.S. by county median household income estimates as of December 2008. 2007 population estimates with 2006 income year; next update December 2009.
Pattern analyses by Proximity using CommunityViewer GIS (CV) with CV project fileset. Use CV and the project fileset on your own Win32 computer. Zoom-in, label, change legend/query/interval settings, add other subject matter, add other geography. Assess patterns, collaborate, make inferences, document conclusions, publish map views/findings, take actions, make positive change happen. Inquire about details. Selected sample views follow.

The Community Development Decision-Making Information Guide (http://proximityone.com/commdev/guide) provides an integrated summary of selected demographic-economic characteristics and patterns for Mississippi and sub-state geography and access to corresponding data and tools for further analysis and extension. The Guide is designed to help further empower stakeholders to better understand the existing conditions and examine how demographic-economic characteristics are changing for wide-ranging application areas and geographies. Design, data, methods, and tools reviewed apply any state or region.

The Proximity state level school/place/county/school district geographic information systems (GIS) enable users to immediately start using GIS capabilities without requiring development staff and time. Rather than developing inflexible maps for regions and areas showing relationships of these interconnected geographies, use the power of GIS on your Win32 computer.
This section illustrates potentials of using the California School/Place/County/School District GIS. Add other geography and/or subject matter to the project. A few getting started, illustration views and suggestions are provided below. Refer to the CV>Help User Guide for more information.
Places. January 1, 2008 vintage. TIGER/Line shapefile precision. School Districts. 2007-08 school year (January 1, 2008) vintage. TIGER/Line shapefile precision. Schools. 2006-07 school year vintage.
Start-up View
County layer is used twice. The upper instance has a solid black county boundary with county name label. Click this layer off to remove labels. There are many ways to label, this shows one easy way. The lower county layer has a transparency setting with a muted gray wider boundary appearance.
Layer selection & Viewing. Uncheck/check the layer in legend to turn off/on this layer view. Example using K-12 Schools layer:
Uncheck places so only districts and counties appear.
Label a layer. Dbl-click School Districts layer, starting layer editor. Click the Labels tab. To make label for Elementary districts visible, click Visible checkbox, click OK to close editor.
Elementary districts now labeled. Proceed similarly to label any layer or layer interval/section.
Identify Tool -- Profile a Geographic Object -- School District Example Reopen the project File>Open c:\cv\cafiles\ca1.gpr Make the school district layer active (click it, it turns blue) Select the Identify tool (i tool on toolbar) Click once in the district shown below. The mini profile is displayed.
Find a Geographic Object -- find and show district named like "Morgan Hill" Click the binocular tool on the toolbar. The Search form appears Select LayerName=Districts, Fields=NAME1, Operation=Like and Value=Morgan Hill% In the map, the selected district flashes. If the fill pattern (layer editor) is set to solid, the selection will show as yellow.
View Data in Grid/Spreadsheet. Example using schools. Start Tools>dBrowser.
When browser form appears, Open c:\cv\cafiles\sch0607_ca.dbf Schools are displayed in a tabular manner. See operations in CV user guide
Printing Map Views. While a printing operation is available, you might find graphics capturing much faster easier and effective. We suggest using the http://www.techsmith.com Snagit tool.

| Edge2Street Update |
The Proximity Edge2Street tool converts a TIGER/Line edge shapefile to a roads/streets shapefile. These road/street segments are inclusive of all types of roads from Interstate to neighborhood streets to dirt roads. The Edge2Street tool is available both as a standalone program and as an integrated CommunityViewer GIS feature.
While the Census Bureau TIGER/Line shapefiles cover many types of geography, there is not a roads/streets shapefile structured in a manner familiar to many users. To accommodate traditional methods of address geocoding and related applications using street segments, the Edge2Street operation is used. The TIGER/Line edge shapefile (or all lines) is the starting point to develop the streets shapefile.
An extended shapefile dbf is created which contains all of the original edge shapefile dbf fields, content and structure. The roads shapefile dbf also contains important fields derived from the edges shapefile dbf, faces dbf, and addr dbf. The augmented roads shapefile dbf contains fields that will be recognized by users of the previous streets shapefiles enabling use of this streets shapefile with legacy software for geocoding and address-matching not possible using the edges shapefile.
See examples of using the Edge2Street operation and results.

This section summarize tools and resources to use these first demographic updates since Census 2000 for areas with population 20,000 to 65,000. These annually updated "three-year estimates" were released in December and are based on data collected from 2005 to 2007.
In 2010, Census plans release of estimates based on the period 2005 to 2009 and will include the smallest of geographic areas — down to the tract and block group levels.

The housing price index by metropolitan area for 4th quarter 2008 data are scheduled to be released by the Office of Federal Housing Enterprise Oversight (2/24/09) and will be accessible in the MetroDynamics (MD) database.

Fourth quarter 2008 census tract demographics are now accessible via MetroDynamics. The extended census tract profile, accessible for any of the U.S. approximate 65,000 census tracts, now includes selected Census 2000 demographics, 2008 demographics by quarter. See additional information and examples of viewing/analyzing these tract demographics with MetroDynamics.
