					        The conversion of the March 1996 CPS to 1995 TRIM2 data files has been completed. The
resulting TRIM2 files are VSY1ONU.CPS95T2.ACTIVE.C0 on tape volume 056091 and
VSY1ONU.CPS95T2.MASTER.C0 on tape volume 003004. A copy of the master file also resides
on MSS and is named VSY1ONU.CPS95T2.MASTER.ONMSS. The only error noticed during
conversion was the inadvertent omission of a new field, FIPS state code, in columns 42-43 of the
household record.

         Due to budgetary constraints, the CPS national sample was reduced from 56,000 to 50,000
eligible housing units beginning with the 1996 survey. Consequently, weights on this file are higher
than before. Precise counts for the post-conversion 1995 TRIM2 files follow. For comparison,
counts are also provided for the 1994 files. (Post conversion numbers may differ somewhat from pre-
conversion numbers because the conversion process may combine or split families to conform to
TRIM2 requirements.)

Counts from the 1996 Technical Documentation (pre-conversion numbers) are Household: 63,339;
Family: 55,882, and Person: 130,476. The household number of 63,339 includes 13, 657 empty
households (households having no family or person records) that are deleted in the first conversion
step. The first conversion routine created one additional household when a household having more
than 7 families was split. The number of families is reduced when children in children-only families
are merged into primary families.


Variables Returned to the File

         Six household level health-related variables were returned to this year’s file after their absence
last year: HCMCARE, HCMCRNO, HCHI, HCHINO, HCHINRH, and HCHINRNO. Users are
alerted to the following statement in the Technical Documentation with regard to these codes. While
these were created from the new health insurance items, they are as consistent as possible with the
1994 and earlier recodes. Also, eight person level migration codes were returned to the file this year:
RESLYMOV, MIGMTR3, MIGMTR4, LIVMLY, MIGREG, MIGFIPS, MIGPLAC and PLACLY.
Please refer to existing documentation (the TRIM2 Codebook) for information about these variables.

   ERNELG, the earnings eligibility flag, has also been returned to the file and, thus, is no longer
coded during conversion, as it was for the past two years when it was missing from the CPS file. The
information we had last year about the current earnings sample including the entire work force and
not just persons in one of the two outgoing rotation groups has been contradicted this year. Census
has informed us that this sample has always included just the quarter in the outgoing rotation groups,
and the values for the flag variable on this year’s file indicate that only a quarter of the workforce is
included. This means that the ERNELG flag on the 1994 TRIM2 files is not reliable, since it was

coded for all members of the workforce. This flag was coded for only members in the two outgoing
rotation groups for the 1993 TRIM2 files, so it should be reliable for that year.

New Variables

         As mentioned before, Census intended to include FIPS state code on the 1996 CPS file, but it
was inadvertently omitted. However, another new code, FIPS county code, is now available. The
TRIM2 name is FIPSCC; it is taken from the household record, columns 50-52, and is made a family
variable in TRIM2. Additionally, many or all of the person level health-related variables that were
made available to us last year in a supplemental file that we merged onto the main file have been
included on this year’s file, along with new allocation flag variables. These new variables are shown
in the following tabulation. (Note that HITYPE1-6 and HICURTP1-5 represent 11 separate fields
that are intended to identify all other health coverage an individual may have.)

   Three other new variables were picked up for our TRIM2 files for the first time this year. They are
shown in the following tabulation.

    For those of you who consult the CPS Technical Documentation directly for information about file
contents, please note that the documentation is in error with regard to the fields in person record
locations 476 through 480, whose TRIM2 names are SPOUSEPI, CHILDPI, CHDNRHPI, OTHERPI,
and NONEPI. These fields are not on the file; they are filler only. They were first removed from the
file the previous year.

Topcoding Changes

  Topcodings of four earnings fields have been revised to the following values. (The previous
topcode for all fields was $99,999.)
