Description
The isko package consists of a series of programs to recode ISCO-88 (International Classification of Occupations) codes into other occupational scales. Use the isco package to recode ISCO-68 occupational codes. These programs are Stata versions of the SPSS recode files by Harry B.G. Ganzeboom and Donald J. Treiman, which are available at http://www.fss.uu.nl/soc/hg/ismf.
iskoegp transforms ISCO-88 codes into a 10 category EGP scale; cf Erikson, Goldthorpe, Portocarero (1979). The argument for the iskoegp commands must be a new variable name in which the recoded occupational scale is to be placed. Note that iskoegp requires the specification of variables indicating whether or not the respondent is self-employed and whether the respondent is a supervisor; see options below.
iskoegp recodes into the following categories: 1 "higher controllers", 2 "lo controllers", 3 "routine nonmanual", 4 "sempl with emp", 5 "sempl without empl", 7 "manual supervisor", 8 "skilled manual", 9 "semi-unskilld manual", 10 "farm labor", 11 "selfempl farm". The recoded variable is labeled using egp10 as lblname; see help label.
Options
isko specifies the variable to be recoded. This must be a 4 digit integer containing ISCO-88 occupational codes.
sempl specifies a variable indicating whether or not the respondent is self-employed. A 1 indicates self-employment, all other values are ignored.
supvis specifies a variable indicating the number of employees the respondent supervises. The values 1 and 10 are significant for placement in certain EGP categories.
