Codes and Frequencies
For sample persons aged 18 and older who were working at a paying or non-paying job last week, who had a job or business but were not at work last week, or who had ever worked, OCCUPN104 reports the person's occupation, grouped into 94 detailed occupation subgroups. Please refer to the code tab for more information on different occupational categories.
OCCUPN104 provides a detailed list of 94 occupation subgroups while OCCUPN204 only provides a simple list of 23 major occupation groups. OCCUPN104 and OCCUPN204 correspond to the 2000 Standard Occupational Classification (2000 SOC or the new SOC) subgroups and major groups, respectively, as determined by the U.S. Census Bureau and the Bureau of Labor Statistics.
There are no comparability issues for variable OCCUPN104. However, users are discouraged to compare OCCUPN104 to other detailed occupation variables because the NHIS used 1987 SOC prior to 2004, which has substantially different occupation codes.
For a consistent occupation variable, please refer to OCC1995, which uses the 1995 SOC as the coding scheme to harmonize occupation classifications from 1969-forward. For more information on work by IPUMS NHIS staff to create classifications of occupation and industry that are comparable over time, please refer to our user note on Occupation and Industry Variables.
