{hi:mc_isco08_to_macro()} {hline 2} Translate 4-digit ISCO-08 to Macro-SEC

{title:Syntax}

        {cmd:mc.isco08_to_macro(}{it:varname} {it:case}{cmd:)}

{pstd}
    where {it:varname} contains 4-digit ISCO-08 codes
    and {it:case} selects the employment status column.

{pstd}
    Typical usage:

        {cmd:mc.isco08_to_macro(}{it:varname} {cmd:case.mcempstat(}{it:sempl} {it:supvis}{cmd:)}{cmd:)}

{pstd}
    with {it:sempl} and {it:supvis} as described in
    {helpb _cwcasefcn_mcempstat:case.mcempstat()}.

{title:Description}

{pstd}
    {helpb crosswalk} table translating 4-digit ISCO-08 codes to
    the Macro-SEC - ESEC plus differentiation of SC I and II (11 classes). Note that the Multilevel Socio-Economic Classes
    are defined at the level of minor ISCO groups
    (3 digit); that is, all unit groups within a minor group
    translate into the same class.

{pstd}
    Cases (destination columns), following the same convention as the ESeC
    tables shipped with {helpb 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

{pstd}
    Column 1 is {cmd:.} 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.

{title:Source}

{pstd}
    Multilevel Socio-Economic Classes crosswalk files for Macro-SEC,
    introduced in Smallenbroek, Hertel and Barone (2022); see
    References.
    {p_end}

{pstd}
    {cmd:mc_isco08_to_macro()} is implemented as a wrapper for
    {helpb _cwfcn_isco08_to_isco08_3:isco08_to_isco08_3()} followed by
    {helpb _cwfcn_mc_isco08_3_to_macro:mc_isco08_3_to_macro()}.
    {p_end}

{pstd}
    For plain 9-class ESeC, use {helpb crosswalk}'s own
    {helpb _cwfcn_isco88_to_esec:isco88_to_esec()} /
    {helpb _cwfcn_isco08_to_esec:isco08_to_esec()} rather than a table from
    this package; see {help crosswalk_multiclass##esec:crosswalk_multiclass}
    for why, and note that they take a different case function
    ({helpb _cwcasefcn_esec88:case.esec88()} /
    {helpb _cwcasefcn_esec:case.esec()}, not
    {helpb _cwcasefcn_mcempstat:case.mcempstat()}).

{pstd}
    Class labels: {helpb _cwfcn_labels_mc_macro:labels_mc_macro()}
    {p_end}
