{smcl} {* version 1.0.0 18aug2026}{...} {hi:mc_isco08_to_microclass()} {hline 2} Translate 4-digit ISCO-08 to the microclass scheme {title:Syntax} {cmd:mc.isco08_to_microclass(}{it:varname}{cmd:)} {pstd} where {it:varname} contains 4-digit ISCO-08 codes. No {help crosswalk##case:case} argument is used. {title:Description} {pstd} {helpb crosswalk} table translating 4-digit ISCO-08 codes to the microclass scheme (77 categories). {pstd} Unlike the other {cmd:mc.} tables this one is purely occupational: it does not vary by employment relation, so it has a single destination column and takes no case argument. {pstd} Keys are 4-digit ISCO-08 codes right-padded with zeros: 1000 is a major group, 1100 a sub-major group, 1110 a minor group and 1111 a unit group. A code is matched against its unit group first, then its minor, sub-major and major group. The table resolves at unit-group level, so it is not routed through {helpb _cwfcn_isco08_to_isco08_3:isco08_to_isco08_3()}. {title:Source} {pstd} Crosswalk file for the 77-category microclass scheme, documented in Smallenbroek, Hertel and Barone (n.d.); see References. {p_end} {pstd} The micro-class scheme is a separate 77-category schema built from ISCO-08 occupational titles and descriptions, following the micro-class approach of Grusky, Weeden and Sorensen (2000) and Weeden and Grusky (2005) and emulating the categories of Jonsson et al. (2009). It is documented in Smallenbroek, Hertel and Barone (n.d.). It is not the same thing as the 30-class Micro-SEC scheme, which this package calls {cmd:micro}. {pstd} Class labels: {helpb _cwfcn_labels_mc_microclass:labels_mc_microclass()} {p_end} {title:References} {phang} Smallenbroek, O., F.
