CHANGE NOTICE #20 - 12/99

New Edition of Wave 3 (1993-1994) WLS Sibling data and documentation.

A new edition (DPLS edition 3) of the third wave WLS data has been released.

If you received third wave data before December 1, 1999, please read this notice.

Summary of the Wave 3 - 9/99 (released 12/1/99) update (see below for details):

The THIRD edition of the 1993/94 WLS siblings differs from previous releases in the following way:

Updates and additions were made to the industry and occupation
variables in the following modules: XEMPL, XFUTR, XMARR, and XSSIB

- 1990 industry and occupation variables were added

- Scores for occupational education were added for
1970 and 1990 industry and occupation variables

- Scores for occupational income were added for 1970
industry and occupation variables

- Scores for occupational earnings were added for
1990 industry and occupation variables

- 1970 industry and occupation variables were updated

Data from 17 siblings were added to the Wave 3 mail module.
Questionnaires for these siblings arrived late and this
is the first release containing data from these siblings.
The data from these questionnaires was added to the
mail survey module: WLS23SMU.DAT

Two of the late arriving 17 questionnaires were for
siblings from groups 0 and 1 who were surveyed by mail
only. Those mail questionnaires contained a subset of
questions that were asked on the telephone questionnaire
for all other respondents. Data for these questions was
added to XBEGV, XEDUC, XKROS, XMARR and XEMPL.

Updates have been made to correct minor errors in data and
documentation in the following modules: XBEGV, XCOGN, XEDUC, XEMPL,
XFUTR, XJOBC, XKROS, and XMARR.

Minor updates were made to improve documentation for all modules.

New release of WLSGV Extract Program includes all added variables.

Details of the Wave 3 - 9/99 updates:

Updates and additions were made to the industry and occupation variables in the following modules:

- Scores for occupational education were added for
1970 and 1990 industry and occupation variables

- Scores for occupational earnings were added for
1990 industry and occupation variables

- Scores for occupational income were added for 1970
industry and occupation variables

- 1970 Census coded industry and occupation variables were updated

Any 1970 census occupation and industry codes that were determined to
be incorrect during the coding of the 1990 codes were updated in the
12/99 releases. All associated scores were also updated.

The updated 1970 variables appear in the same columns as the original variables,
but have a "U" appended to the original variable name. If the current variable
name already had a "U" appended from a previous update, then the new variable name ends in "U2".
The original 1970 variables retained the same names as previous releases,

(Original variable-not recommended.)

See Change Notice #19 for difference between updated and original variables.

The updated variables retain the same names with the initial "0" replaced with a "U"
Housewife (code 985) is no longer a legitimate occupation code for the 1970 updated variables
Minor corrections in data have been made in this release

The following is an example of one of the updated 1970 industry/occupation series:
