About the Visual Data Analytics Geographic Information System The Visual Data Analytics (VDA) Geographic Information System (GIS) was used to develop the above maps. You can use VDA GIS to develop variations of the maps; different intervals, colors, zooms, etc. There is nothing to install. VDAGIS tools and data have been developed and are updated/supported by Warren Glimpse/ProximityOne/Alexandria, VA USA and Takashi Hamilton/Tsukasa/Osaka, Japan. See more about VDA GIS.

Congressional Community Boundaries
About Congressional DistrictsWe develop Congressional Community boundaries (shapefiles) based on census blocks. A set of 17-18 CC boundaries exaclty matches the corresponding congressional disitrict. These boundaries are knitted together with other geography as shown in the above iVDA GIS project. The boundaries can be used with other boundaries, such as census tracts are related subject matter, to view a very with array of patterns. We are now developing boundaries for the 120th Congressional Districts. Census 2020 and ACS 2024 Itemset1 Datasets for CCs and CDs The Congressional Community data used in the VDA GIS project shown above are aggregated data using census block Census 2020 Demographic Profle 1 data for CC boundaries. There are 160 items for each CC. These data are developed as a DBF data file and have many other uses in addition to mapping the data. Separate from the Census 2020 data, we develop updated data using the ACS data based on census tracts. These data are ACS 2024 Itemset1 data comprised from a selection of roughly 250 selected from the ACS 2024 Demographic Profiles for census tracts. The tract data are aggregated to CCs. Those tract split by the CC boundary are allocated to one CC verus another using Census block level data. We are now developing new boundaries and subject matter data that will be used with the CD 120 vintage geographyc and ACS 2025 data that will be released later in 2026. VDA GIS Projects Featuring CC Boundaries with Integrated Subject Matter The iVDA GIS project above illustrates how Congressional Community boundary with integrated Census 2020 data can be used. Comparative Demographic Analyses of CC 51-08-005 with CD 51-08 CCs nest within CDs, exhausting the CD land/water area. These reports provide a comparative analysis of demographic characteristics of a CC relative to its CD based on Census 2020. Using the Demographic Analysis (DA) compare your CC with other CCs of CD. These are both HTML documents designed to optionally print to 8.5" x 11" dimensions. The tabular looks more like a spreadsheet while the narrative report provides a comparation more in a flowing narrative and adds contextual detail. • Tabular Report • Narratve Report For example, the narrative report tells us that the dependency ratio in 2020 was 28.27 for CC VA 08005 compared to 50.38 for CD118 VA 08 -- both compared 63.6 for the U.S. overall. Read the narrative report to see why this can be important to our CC. Comparative Demographic Analyses of CC 51-08-005 with CD 51-08 -- using annual ACS data The Demographic Analysis 2 provides an ability to compare a CC to a CD using annual American Community Survey data (ACS 2024). DA2 also provides extensive graphics. • Narrative Report CC 5108005 (501) ... CD VA 08 (500) ACS 5-year Population Pyramids for CC 51-08-005 and CD 51-08 The ChartGraphics tool is used to develop a population pyramid for CCs, CDs and other geography. ChartGraphics is a tool for visualizing population distribution by gender and age for an area. We have developed Census 2000 CC files and ACS 2024 CD files for use with ChartGraphics. We are now developing an all U.S. CC ACS 2024 and a U.S. county ACS 2024 file for ChartGraphics. Users may develop their own files. • Population Pyramid for CC 5108005 Census 2020 • Population Pyramid for CD 5108 20024 The U.S. 435 119th Congressional Districts (Jan 3, 2025 to Jan 3, 2027) have an average population of approximately 763,000 population, larger than three states. See related 118th CD demographics interactive table. The size and diversity of CDs can make it difficult to communicate effectively with Congress. Congressional Communities are subdivisions of Congressional Districts, can help Americans better have their voice heard by Congress. Patterns of Economic Prosperity by Congressional Community .. Washington, DC metro area; a focus on Virginia 119th CD 08 .. this is about where we are. The graphic below shows Congressional Communities (CCs) with black bold boundaries and labeled with CC code. Congressional Districts are shown with bold brown boundary and white boxed CD code label. Marker shows code for VA CD 08 and is located in CC 5108017. There are 18 CCs that comprise CD 119. Patterns of economic prosperity (median household income) by tract are shown by colors/intervals in the inset legend.  Congressional Communities .. goto top The Congressional Communities program is an initiative of the nonprofit Congressional Communities organization. As a resident, constituent, of a congressional district, how do you make your voice heard on key issues affecting you, your household and your local living environment in Congress? Congressional Communities, subdivisions of Congressional Districts, can help Americans better have their voice heard by Congress. Congressional communities are developed by assembling 2020 census blocks and block groups by the Congressional Communities team. Congressional districts are sub-divided into CCs, sets of contiguous blocks/block groups, that are typically around 40,000 population based on a range of socioeconomic, geopolitical features, geographic and other factors. A set of Census 2020 and American Community Survey demographics are developed for each CC. These demographics help CC stakeholders better understand characteristics and needs of their CCs and other CCs. The sum of the total population (and other demographic attributes) for all CCs nesting in a CD equals the CD total population. The CD demographics are the aggregates of the associated CCs, yet the CCs have their own unique characteristics. Unlike census tracts, averaging 4,000 population, CCs nest within CDs and better reflect neighborhood-plus characteristics. Unlike cities, CCs include rural and suburban areas and sub-divide larger cities. The Pentagon City Congressional Community .. goto top We have used the VDA Web GIS to locate/view our CC.
