... using geographic information system (GIS) resources to examine the changing political landscape.
See new state by state sections focused on access to and use of "enacted redistricting shapefiles."
Enacted Redistricting Shapefiles (ERS) are shapefiles that have been developed as the
result of legislation enacted by a state or other governmental entity through the redistricting process,
based on Census 2010 data, that define/show new political area boundaries.
Focus is predominantly on state by state 113th Congress (January 2013) congressional district boundaries and related state house and senate boundaries.
Visit http://proximityone.com/ers.htm,
install the software and files, and starting using the resources to view/geospatial analyze these new data.
In most cases, existing district boundaries for state house and senate districts will
remain in effect until the term of office for legislative office holders expires
at the beginning of the legislative session in January 2013.
New district lines will be used in 2012 only for the purposes
of determining the district boundaries for voters voting in the 2012 primary,
primary run-off and the general election.
Individuals elected to office in November 2012 will represent the
newly configured districts when sworn into office in January 2013.
States will progressively finalize congressional and state legislative boundaries
during the year ahead. In many cases, demographic analysis for the 113th Congressional District and
state legislative districts can start now.
In circa May 2013, the Census Bureau expects to release the 113th Congressional District boundary
shapefiles and Census 2010 data retabulated reflecting the 113th Congressional District boundaries.
Analysts and stakeholders do not need to wait for the Census Bureau sourced data.
While Census-sourced data may be required for official purposes, state-sourced boundary files
and existing census block demographics can be used well in advance of the Census-sourced updates.
Contact us (888-364-7656) for more information on developing and analyzing data for the
new 113th congressional district and state legislative boundaries,

New congressional district and state legislative district demographics ... the Census 2010 Demographic Profile Summary File (DPSF) is the second major Census 2010 dataset,
released in May 2011 following release of the P.L. 94-171 redistricting data.
The DPSF contains approximately 200 subject matter items ...
100 percent data asked of all people and about every
housing unit on topics such as sex, age, race, Hispanic origin, household relationship, household
type, group quarters population, housing occupancy, and housing tenure.
The DPSF is released as individual files for the U.S., each state, D.C. and Puerto Rico.
Released on a flow basis, data for all states are expected to be available by the end of May.
These are the first "more detailed" age-related and household characteristics data to be released from
Census 2010. The low-level tabulation geography is city/place and minor civil divisions ... there are no census
tract or school district summary data included.
Access the DPSF data using the Situation & Outlook software/database.
Integrate the Census 2010 DPSF data with ACS 2009 "richer demographics" data.

Use the interactive ranking table at http://proximityone.com/cen2010_pl94171.htm
to view selected summary level data, including congressional districts, for all states as the data become available (updated weekly).
01.20.11. Census 2010 Census Block Demographics
Census 2010 census block level data will start to flow during the first week of February.
These "redistricting" data will be followed by more detailed subject matter by census block during the summer 2011 (such as single year of age).
Census releases the redistricting data in the form of raw data files. These data must be integrated with mapping/GIS tools, TIGER/Line files, and other data to undertake the
redistricting process.
The Census Bureau TIGER/Line shapefiles include state by census block boundary files as well as
shapefiles with boundaries for other political and statistical areas. Using GIS tools, the census block demographics may be integrated with the TIGER/Line census block shapefiles.
Then, yet other TIGER/Line (and other) shapefiles with coverages for roads, rail, water features, and other features may be linked together with the census block and political/statistical shapefiles
within a GIS project/application.
See the Gallery map views showing Atlanta area congressional districts in the context of census blocks, interstate and Atlanta city.
As the demographic data become available these views will be updated to illustrate pattern analysis and redistricting using these data.
Redistricting is required by various state and local regulations for wide-ranging areas such as cities and school districts.
Contact us to assess redistricting for your areas. Mention redistricting.
12.10.10. Using the New ACS 2005-09 Small Area Demographics
Are you a prospective user of the Census Bureau American Community Survey
2005-09 5-year small area demographics? These new estimates (release date 12/14/10) have received a great deal of attention because they are the first small
area (block group, census tract, city, county, etc.) "richer demographics" available for all such geographic areas, wall-to-wall across America,
since Census 2000.
They are not part of Census 2010.
Congressional district demographics are included in the "2005-09 5-year estimates."
But ... the ACS 1-year estimates released in September are more accurate, relate more to 2009 rather than 2007, and have less suppression that the 5-year estimates.
Data described below (in the ranking table and related individual district profiles), make use of the September 1-year estimates.
However, most congressional district stakeholders will be interested in the "2005-09 5-year estimates" precisely because they can tell you more about the
geographic disaggregation of congressional districts. What are all of my cities [counties, school districts, etc.] like?
Note that in using the "5-year estimates" and the "1-year estimates" the data values for the same subject matter items (e.g. total population) will differ.
As a generalization, the ACS 2009 "5-year estimates" are centric to mid-2007 while the ACS 2009 "1-year estimates" are centric to mid-2009.
See the ACS main page for more details.
Join us in a webinar where we discuss issues concerning access to and use of these data.
11.25.10. 76th Congress .. 132 Million Population .. 1940
Now 70 years since FDR addressed the 76th Congress in 1940, the demographics of the United States, as well as Congress, have changed remarkably.
In the Congress of 1940, there were 526 men and five women, nearly 300 lawyers, two dozen school teachers, sixty merchants, twenty bankers and insurance agents, nine newspaper publishers,
five dentists, half-dozen preachers, owner of the largest cattle ranch in the world, an amateur magician and half-dozen or more presidential aspirants. There was one Negro.
(No Ordinary Time by Doris Kearns Goodwin.)
America's then 132 million population, and including The Greatest Generation, has changed into today's 310 million population.
The 1940 Census was the first decennial census to make use of the sample-based questionnaire and produce the "richer demographics."
See these tables to compare/contrast 1940 and 2000 demographics.

01.12.10. County Vote Likelihood Projections: 2010/2012
(toggle)
As the 2010 and 2012 November elections approach, we seek to assess factors that might make the outcomes different from those of 2008.
That is, what will the vote or percent vote by county be for each major party and candidate?
Clearly, many 'what-ifs' come into play.
The following view shows the 2008 Presidential election vote by county.
See larger view.
To learn more about what might be ahead and examine this at the county level, factors that would shape the 2012 presidential outcome
would include and 'employment situation' factor and an 'incumbent popularity' factor.
The specific candidate and many other factors go into the mix in determining the outcome.
The above map view is based upon a dataset that includes the 2008 presidential vote by candidate and other items not shown in this view.
'Likelihood models' that predict possible 2010 and 2012 outcomes will be reviewed forthcoming Patterns.
The models make use of a mix of variably weighted factors.
Indexes are computed at the county level based on a quantified value for each factor and added to (or updated in) the
dataset. Using the models, data and related tools, other GIS layers can be viewed/examined that depict alternative outcomes (votes, percent vote, etc.) by county.
What is your interest in being a part of this?
Red or blue? Before 2000 in the U.S., and possibly more generally throughout the world, blue has been associated with the more conservative party
and red with the more liberal party. More recently, news organizations have tended to reverse this pattern.
The above map shows blue associated with Republican/McCain and red associated with Democrat/Obama.

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.

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

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 2010?
• How will the population change in a district change by 2020?
• 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.

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.
Examining K-12 Schools & Enrollment by Congressional District [goto top]
How many K-12 schools are in my congressional district?
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:
Schools
359
Teachers (FTE)
7977
Students, Total
109,870
White
100,022
Black
8,496
Hispanic
717
in Free Lunch Program
41,277
in Reduced Lunch Fee Program
9,624
PK Enrollment
2,579
12th Grade Enrollment
7,230
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.
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.
