This database contains occupational wage data for 164 occupations in 192 countries from 1953 to 2008. The occupational wage data are derived from the ILO October Inquiry database for 1983-2008 (http://laborsta.ilo.org) and various ILO publications for 1953-1982 (see Table 1 Freeman and Oostendorp 2000, NBER WP #8058) by calibrating the data into a normalized wage rate for each occupation. The normalized wages refer to average hourly or monthly wage rates for adult 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

 

Wage data are reported with variable names PwTwW_C, where P indicates whether it is an hourly or monthly wage, T the calibration type, W the weighting type, and C the currency type:

 

P{h,m}                          Period:

h = hourly wage

m = monthly wage

 

T{1,2,3,4}                     Type:

1 = standard data (no calibration)

2 = country-specific calibration

3 = country-specific calibration with imputation

4 = uniform calibration

 

W{l,u}                          Weighting:

l = lexicographic weighting

u = uniform weighting

 

C{current,present,us}      Currency:

current = in reported LCU

present = in present-day LCU

us = in US$

Note: It is recommended to start any analysis conservatively with the non-calibrated data (hw1wl_C and mw1wl_C) and next to use the standardized data Pw2wW_C  and Pw3wW_C (with increasing levels of data calibration / imputation). The standardized wage with country-specific calibration and imputation and lexicographic weighting (hw3wl_C and mw3wl_C) is recommended for use because it provides the largest sample, it uses country-specific calibration to the extent possible and it uses lexicographic weights favoring raw data reported in standard format. The standardized data Pw4wW_C do not use country-specific calibration and correspond to the standardization variant 2 in the initial release of the data for 1983-1998 (see NBER Working Paper #8058, table A.1). It is included for comparison.
