Congressional Communities
  -- Helping Americans Make Their Voices Heard by Congress

Making your voice heard to Congress on matters that affect you ...

The U.S. 435 118th Congressional Districts (Jan 3, 2023 to Jan 3, 2025) 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 118th CD 08
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 118. 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. ProximityOne has been engaged by Congressional Communities to assist with development of CCs and CC data and to provide software, data, support and advisory services. ProximityOne and Congressional Commmunities are separate organizations.

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 using the ProximityOne CV XE GIS software and state GIS projects. 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.

Where is my Congressional Community? .. goto top
You can use the VDA Web GIS to locate/view a CC based on an address.
Follow these steps:
Start VDA Web GIS -- https://vdagis.com
.. no fee and learn more about VDA Web GIS getting started
Next, select the MetroDynamics Project
After VDA map interface displays, proceed as follows:
Select the "Cong Community Code" layer in the upper left dropdown (making the "active" layer)
Enter an address in edit box above the map window then click the Find Address button.
.. for this example, use Reagan National Airport" (no quotes)
.. the map window refreshes with a zoom to that location and shows a marker at that address.
Click the marker to show the CC associated with that location.
.. the CC area shows in the Map Window (cross-hatched) and a CC Profile displays in the lower left panel.


See in the profile that this is CC 5108005 (State 51 and 118th CD 08 and CC 005)
.. also sse the Census 2020 population for this CC is 56,095.
.. the Census 2020 percent majority-minority population is 47.5.
Click the HMTL button, lower left below profile for a Web-based page view

To view all CCs and their codes, click on the two layers: Cong Community Code and Cong Community

Examining All CCs in a CD .. goto top
The following graphic shows another way to examine how the CCs in a CD relate to each other. This tabular view shows all CCs in VA 118th CD 08 as rows with demographics arrayed across columns. CC 5108005 is highlighted.

To develop the above view, proceed from above.
Click the Table/Query button at far right below the Map Window.
.. the view refreshes showing the data grid/table below the Map Window.
To view the CCs in VA CD 118, enter the query <ccn20 like '5108%'> (no pointy brackets) and click the query button.
.. the grid refreshes showing the 18 CC rows for this CD
To view the CC 5108005, click on that row, it turns blue, then click the button "Click geography row to display".
.. the Map Window view zooms to that CC.

More About Congressional Communities
Many CDs cover large areas, are elongated and extend over long distances and include areas very different from one another. Residents of congressional districts need a way to more effectively communicate their needs and participate in policy development. Providing a better voice from CD component areas can improve through Congressional Communities.

Congressional Communities (CCs) are geographic subdivisions of Congressional Districts (CDs). Developed and coordinated by the non-profit Congressional Communities organization, CCs offer a local identity -- characteristics more of that locale than the CD overall. Congressional Communities are intended to better enable Americans to make their voices heard by Congress.
