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. {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. {pstd} Cells that the source tables leave unclassified are coded {cmd:.} and produce a missing value. {title:Source} {pstd} Multilevel Socio-Economic Classes crosswalk files for Micro-SEC, the 30-class scheme assessed in Hertel, Barone and Smallenbroek (2025); see References. {p_end} {pstd} Note that this table is based on {browse "https://warwick.ac.uk/fac/soc/ier/research/classification/isco88":ISCO-88(COM)}, the European Union variant of the ISCO-88. If your data contains ISCO-88 codes you might first want to translate these codes to ISCO-88(COM) using {helpb _cwfcn_isco88_to_isco88com:isco88_to_isco88com()}. {pstd} Class labels: {helpb _cwfcn_labels_mc_micro:labels_mc_micro()} {p_end} {title:References} {phang} Hertel, F.
