[EL] Query - Counties and Congressional Districts

I thought I would give Justin Levitt a chance to answer this question. He’s
compiled many of states’ congressional district boundary data and links to
primary sources here:
http://redistricting.lls.edu/2010districts.php
For some cases, like Arizona, the block equivalency files may not be listed
by Justin, but are available on the state website which he links to. In some
other cases, work will be needed to convert a shapefile (or worse, an image)
to a block equivalency file.
Once one has the block equivalency files, one could easily use the county id
embedded in the unique block id to generate a list of counties, and one can
do the work of tabulating the 2010 census data that Kim suggests will not be
forthcoming from the Census Bureau.
Justin has posted most of the states, and if I were to speak for him, I
believe that he would welcome anyone who may send him missing data to
complete the valuable service he has provided.

Doug is correct in noting that the link provided is to last decade's
districts. He is also correct in noting what the Bureau reported to NCSL
earlier this week, since we were at the same meeting.
But he did not note a more disturbing piece of information that was shared
with the group, that being that funding cut backs in the Bureau have caused
them to cancel the retabulation of the 2010 census numbers for the new
districts. When they get the district geography into their master system,
they will be able to have new ACS data reported for the districts, but not
old data. Whether these cutbacks affect other data products or tables
remains to be seen.
Who knows, maybe Lillie will turn out to be correct and we'll do this. Of
course, that means I need to come off my constant state of traveling and
find the tine (and $) to do the work.

That is correct: the current Census link provides 2000 Census data and
2001-cycle district lines.
At NCSL earlier this week the Census Bureau reported that it has just
completed collecting the 2011-cycle lines, and that it will use the new
lines in its 2013 release of American Community Service data, which I
believe is scheduled for January.

That link goes to the 2000 census. Is there also a link for 2010 census?

A friend of mine is looking for a convenient data file showing for
all 50 states which counties are located, in part or in whole, in each
congressional district. If you can recommend such a source, please send the
information to me off-list. I'll pass it on to my friend. I believe this
is for research, not a political purpose. Thanks.
