RE: Revised 1999 AHS File

>>Does this imply that there is also a problem with the 2001 national AHS
microdata file?  It seems that if, say, FRSTOC was incorrectly coded in
1999 and the same household was still in the unit in 2001, there's a chance
the
program would perpetuate the 1999 error into the 2001 data. I, and many
others, look forward to any insight you can offer.<<

The 2001 file should not be affected.  We knew about the 1999 problem while
we were processing the 2001 data.  We couldn't fix the 1999 problem right
away, because the same people who were to do that were busy getting the
2001 file released.  But the fix was implemented for the 2001 processing.
