{title:Description}

{p}
The {cmd:isko} package consists of a series of programs to recode ISCO-88
{it:(International Classification of Occupations)} codes into other
occupational scales. Use the {help 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
{browse "http://www.fss.uu.nl/soc/hg/ismf":http://www.fss.uu.nl/soc/hg/ismf}.

The argument for the {cmd:isko} commands must be a new variable name in which
the recoded occupational scale is to be placed. The {cmd:isko} option is used
specify the variable containing the ISCO-88 occupational codes.

{p 0 4}
{help iskoisei} transforms ISCO-88 codes into
an ISEI scale {it:(International Socio-Economic Index)};
cf. Ganzeboom, de Graaf, Treiman (1992).

{p 0 4}
{help iskotrei} transforms ISCO-88 codes into
Treiman's SIOPS scale {it:(Standard International Occupational Prestige Scale)};
cf Treiman (1977).

{p 0 4}
{help iskoegp} transforms ISCO-88 codes into
a 10 category EGP scale; cf Erikson, Goldthorpe, Portocarero (1979).
Note that {cmd:iskoegp} requires the specification of variables indicating
whether or not the respondent is self-employed and whether the respondent
is a supervisor; see {cmd:options} below. {cmd: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 {cmd:egp10}
as {it:lblname}; see help {help label}.

{p 0 4}
{help isko8868} transforms ISCO-88 codes into
ISCO-88 codes; cf ILO (1990).

{title:Options}

{p 0 4}
{cmd:isko} specifies the variable to be recoded.
This must be a 4 digit integer containing ISCO-88 occupational codes.

{p 0 4}
{cmd:sempl} specifies a variable indicating whether or not
the respondent is self-employed. A 1 indicates self-employment, all other
values are ignored. Applies only to {cmd:iskoegp}.

{p 0 4}
{cmd: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. Applies only to {cmd:iskoegp}.
