Please refer to notes on page 6-12 of the original documentation about
the health and migration data, and to User Note 7 page I-15 to put this
into context.
- The record size has changed from 744 to 756. New variables are in
formerly padded fields or at the end of the record, so old formats
will work.
- The health variables issued with the last corrected file, as well
as the new migration variables issued with this new file are now
present in the machine-readable data dictionary file included
on the CD.
- Redesign of the Health Insurance items in 1995. Although the resulting
data were recoded into categories compatible with 1994, the redesign
makes the results non-comparable because the 1995 CPS was more accurate
in identifying which dependents were covered by health insurance.
- The 5 year migration data are now available in the person record
columns 213-255 as well as 635-636. This is the only 5-year question
that the CPS has had this decade, and it can be compared with the
1990 Census findings. Remember, though, that residents of institutions
like dorms, barracks, and prisons are not included in the CPS.
- The 1-year migration data have been included in this release in
columns 744-754. Analysis of these data by the Census Bureau has shown
them to be somewhat inconsistent in quality. Stick to the 5-year question
if you want migration data.
- Weights by race are off for 1994 and 1995 As an example of
magnitude, the 1996 CPS documentation on page 5-6 shows what the race
counts are before after Census changed the edit in July of 1995: Asians
before changed edit5.5 million; after the change9.5 million.
This error echos across the other race groups as well.
- Compared with the 1994 CPS, more countries have been added to citizenship,
immigration, nativity and parents' nativity questions. In the present
release these variables are correct. There have been problems
in previous releases. With this release, there is a new variable on
country of previous residence, as opposed to country of birth.
- There is a new subdirectory, DOCUMENT, that contains machine-readable
versions of the codebook information beyond the data dictionary. Examples
of useful items in this document directory are the occupation, industry,
and country of origin codes.
