mc_isco08_3_to_micro() -- Translate 3-digit ISCO-08 to Micro-SEC

Syntax

mc.isco08_3_to_micro(varname case)

where varname contains 3-digit ISCO-08 minor group codes
and case selects the employment status column.

Typical usage:

mc.isco08_3_to_micro(varname case.mcempstat(sempl supvis))

Description

crosswalk table translating 3-digit ISCO-08 minor
groups to the Multilevel Socio-Economic Classes: Micro-SEC (30 classes). The table also
carries rows for sub-major (2-digit) and major (1-digit)
groups, written as 3-digit codes padded with zeros on the
right, so that partially coded observations still match.

Cases (destination columns), following the same convention as the ESeC
tables shipped with crosswalk:

1 = employment status unknown
2 = employed, without supervisory status
3 = employed, with supervisory status
4 = self-employed, no employees
5 = self-employed, 1-9 employees
6 = self-employed, 10 or more employees

Column 1 is . throughout: the Multilevel Socio-Economic Classes have no simplified
variant for unknown employment status, so observations whose employment
status is unknown come back uncoded rather than picking up another class.

Cells that the source tables leave unclassified are coded
. and produce a missing value.
