This
database contains occupational wage data for 161 occupations in over 150
countries from 1983 to 2003.
The occupational wage data are derived from the ILO October Inquiry database (http://laborsta.ilo.org, Table 01) by calibrating the data into a
normalized wage rate for each occupation. The normalized wages refer to average
monthly wage rates for male workers.

You
will need a major database, statistical program, or programming language to use
these files. This dataset is too large to load completely into MS Excel 2000,
which has a maximum of 65,536 observations, though Access can be used to read
the ASCII datafile. Users without STATA may be interested in STAT/TRANSFER. This program can
translate STATA files into other formats including other statistical packages,
database packages and spreadsheets. Among statistical packages supports are
SPSS, SAS, and Systat.

Calibration Info
Different calibration procedures have been used to
normalize the data, and the suffix to the variable x indicates which
calibration method has been used:
|
x1 |
wage reported in
standard format in raw data |
|
x2wu |
wage with
country-specific calibration, uniform weighting |
|
x2wl |
wage with
country-specific calibration, lexicographic weighting |
|
x3wu |
wage with
country-specific and uniform calibration, uniform weighting |
|
x3wl |
wage with country-specific and uniform calibration,
lexicographic weighting |
|
x4wu |
wage with uniform
calibration, uniform weighting |
|
x4wl |
wage with uniform
calibration, lexicographic weighting |
It
is recommended to start any analysis conservatively with the non-standardized
data x1 and to use the standardized data x2 and x3 (with increasing levels of
data imputation) only if the basic results remain unaffected. If the basic
results are unaffected then the standardized wage with country-specific and
uniform calibration and lexicographic weighting is recommended for use because
it provides the largest sample. The standardized data x4 do not use
country-specific calibration and correspond to the standardization variant 2 in
the prior release of the data (see NBER Working Paper #8058, table A.1) and has
commonly been used in analyses so far. Hence we include this type of standard(ized) data for
comparison.
