The County to County Migration Flow Files CD-ROMs were issued January 1995.
Since then we have discovered that a few of the files contained erroneous or
incomplete data.  We have created and released corrected files.

The states and counties on the In-Migration CD-ROM for which corrected files
have been produced include:

  Table data: Palm Beach (099), Pinellas (103), Polk (105), Putnam (107), 
              St. John (109) and Sarasota County (115), FL (12); Stone (209),
              Sullivan (211), Taney (213), Texas (215) and Warren County
              (219), MO (29)

  Summary data: state of FL (12), Palm Beach (099), Pasco (101), Pinellas 
                (103), Polk (105), Putnam (107), St. John (109) and Seminole 
                County (117), FL (12); state of MO (29), Stone (209),
                Sullivan (211), Taney (213), Texas (215), Warren (219), 
                Washington (221), Wayne (223), Webster (225) and Wright 
                County (229), MO (29)

The corrected files reside on the re-issued edition of the In-Migration 
CD-ROM.  

The user notes for the In-Migration CD-ROM have also been updated to include 
instructions and sample programs for converting the binary data files to 
ASCII.  Several users have expressed an interest in a utility for converting
the data since the original CD-ROM was issued.  See the file 
\DOCUMENT\USERNOTE.ASC.

The states and counties on the Out-Migration CD-ROM for which corrected files
have been produced include:

  Summary data: state of MS (28), Harrison County (047), MS (28)

Because only two summary data files were in error on the original 
Out-Migration CD-ROM, it will not be re-issued.  These two files have been
included as a zipped file (GO_CCMFF.EXE) in the \DOCUMENT directory of the 
re-issued In-Migration CD-ROM.  This zipped file is also available for FTP 
copy from the Census Bulletin Board.  The zipped file includes software for 
viewing the two summary data files.  To obtain a copy of the corrected 
files and software from the bulletin board, connect to ftp.census.gov, log in 
as anonymous, go to the directory /pub/CD-Apps and get the file GO_CCMFF.EXE. 
Once you have copied this file from the re-issued In-Migration CD-ROM or the
bulletin board to your hard drive, run it to extract the software and files.  
Then follow the directions in the README file.
