Detailed information on the 111th Congress is available from the Office of the Clerk, U.S. House of Representatives (http://clerk.house.gov/). The boundaries and codes/names are the same for the 110th and 111th Congressional Districts. 110th Congressional Districts The 110th Congress was in session January 2007 to January 2009. Only congressional district boundaries in Texas and Georgia changed relative to the 109th Congressional Districts. 109th Congressional Districts The 109th Congress was in session January 2005 to January 2007. Congressional district boundaries in Maine, Pennsylvania, and Texas changed after the 108th Congress was seated in January of 2003, and are reflected in the 109th Congressional District boundary files referenced below. 109th CD Basic Demographics File.

Integrate demographics and your data into the map project. 108th Congressional Districts The 108th Congress was in session from January 2003 to January 2005. This web page reviews the scope and use of these data resources and summarizes Proximity information resources that can be used to process, integrate these data with your own data, and interpret the data, and help with decision-making analyses. Some examples presented below are based on the 108th CDs. How and Where Have Congressional Districts Changed? 
Using the State of Missouri as an example, the above graphics show Missouri by 107th CD, 108th CD, and 107 superimposed on 108. County boundaries are shown in gray. It is evident that CD 09 has expanded to the south and southwest and contracted in the area north of St. Louis. Several other Districts have had similar changes. This pattern of changing district boundaries is typical of most states with more that one district. Using Census 2000 demographics it is possible to determine how the demographics of the overall district have changed -- resulting only from the changing geography. That is, these data show change resulting from change in geographic territory only -- not reflecting change in population growth or composition over time. Missouri Congressional District 9 had a Census 2000 total population of 694,873 based on the 106th (and 107th) CD boundary and 621,690 based on the 108th CD boundary. The following table compares the difference in educational attainment for Missouri CD 9. More detailed attributes the 108th Congressional District may be viewed via Sample Data Profiles or Complete Count Profiles.
Measuring and Planning for Change: -- Post-Census, Extended Demographics and Regional Economy Proximity develops and integrates demographic, business, economic, and geographic data to help leaders and stakeholders answer a wide range of questions. • How has the population changed in a district since Census 2000? • How will the population change in a district change by 2010? • What are the opinions and views held by the residents of a district? • How many schools are located in the district and how is enrollments changing? • What is the source and use of education funding and how is it changing? • What is the size and distribution of business establishments by industry? Knowing answers to these questions (as examples), can help leaders and stakeholders set realistic objectives for the district and devise strategies and identify policy and program changes needed to achieve related goals. Proximity can help implement this total process. Using Geospatial Analysis and Geographic Resources Maps and Visual Analysis. Integrate the Census 2000 data, secondary data updates, and your own data and visually analyze these data. The following map shows the power of using these resources.

Using the 108th CD Map Files and Your Data. View your own data on your PC using the 108th CD boundary files, to depicting the perimeters of congressional districts and thematic maps showing geodemographic relationships. Boundary files may be downloaded from the Census Bureau boundary file Web server (http://www.census.gov/geo/www/cob/bdy_files.html). These boundary files were used to develop the map graphics shown above. Contact Proximity to learn more about how to use these map files with your data. Below is an example using K-12 school data in Missouri Congressional District 8. How Many Schools are in My Congressional District? [goto top] Sometimes determining answers to simple, but important, questions can be very difficult using even publicly available data. Using a GIS, we developed the following map of Missouri Congressional District 8. The icons represent K-12 schools (school year 2000-2001). It is possible to access the school level data from the U.S. Department of Education, but the first step requires converting the data into a form that can be used to meet analytical objectives. Second, to display the school locations as icons requires the availability of the school latitude-longitude. The values are available in the DOE data for about half of the schools. For those missing these data, we added the latitude-longitude based on the centroid of the ZIP code in which the school is located. 
We "clip" the schools located in MO CD 8 and save the data to file easily determining that there are 359 schools (as reported by the Missouri Department of Education to DOE) in the District. The file is then opened using Excel and several attributes about K-12 education on Missouri CD 8 are revealed as follows:
The PK enrollment provides some measure that can be useful in determining relative need for day care facilities, and related matters, (used with other data) in the Congressional District. The 12th grade enrollment data provides some measure of the number of students who will be entering the work force and/or attending a postsecondary education institution. Using the GIS, we can also "drill down" into specific areas in the District that might be of interest. In the next map, a zoom into the previous map depicts schools that are Title I eligible in yellow. We can immediately see the distribution of schools and examine patterns. One school has been arbitrarily selected (at identify cursor) and profiled. This shows how these data used in a GIS context can pull-up specific data about a school. 
Address Matching, Geocoding, Referencing. Address match and geocode your own data using the Census 2000 108th CD TIGER/Line Files. The TIGER/Line files (geographic data only) enable you to assign latitude-longitude to addresses and much more. Released in March 2003, the 108th Congressional District (CD) Census 2000 TIGER/Line files are the latest version of the Census 2000 TIGER/Line files and use the same file format as the other Census 2000 TIGER/Line files. The address ranges appearing in the 108th CD Census 2000 TIGER/Line files are based upon the addresses in the final Master Address File (MAF) used for tabulating Census 2000. These are the same address ranges originally introduced with the Census 2000 TIGER/Line files released in October, 2001. The 108th CD Census 2000 TIGER/Line files coverage is as follows: all counties, parishes, boroughs, census areas and equivalent entities for each state, the District of Columbia, Puerto Rico and the Island Areas. In a few cases the boundaries of the 108th Congressional districts do not follow Census 2000 block boundaries. Where the boundary of a congressional district for the 108th Congress splits a Census 2000 block, the Census Bureau maps and TIGER/Line files depict the correct location of the boundary. For data tabulation purposes, that census block is fully allocated to the 108th Congressional District specified to the Census Bureau by the state. This list provides all the 108th Congressional Districts that split census blocks and shows the congressional district where the block is allocated for data tabulation. Poorest Congressional Districts. The following table lists the 20 congressional districts having the lowest median household income based on Census 2000 (income in 1999). 108th Congress Composition In terms of official representation, there are 435 Members, 4 Delegates (American Samoa, District of Columbia, Guam, Virgin Islands), and 1 Resident Commissioner (Puerto Rico) that comprise the 108th Congress. Data reported in tables presented in national analyses on this Web page include the 435 Congressional Districts, D.C., and Puerto Rico. This set of data is used as these data comprise the scope of geography included in the Census Bureau 108th Congressional District Summary File. Additional Information Proximity develops geodemographic-economic data and analytical tools and helps organizations knit together and use diverse data in a decision-making and analytical framework. We develop custom demographic/economic estimates and projections, develop geographic and geocoded address files, and assist with impact and geospatial analyses.
