Important Information About Using Occupations Data
- Beginning in 1994, NLSY79 CAPI administered surveys are preloaded with the last occupation. To reduce errors and save on the amount of coding, each respondent is asked if the occupation reported last time is still correct. Only if the respondent states this information is no longer correct is the occupation recoded.
- "Employer" is the unit for which occupations are asked in the NLSY79. Be careful in making inferences about occupational mobility as miscoding is present. When occupation codes for the same employer in adjacent interview years are compared (see Work History Data for more information on linking employers across rounds), it has been found that respondents use slightly different words to describe their occupation and coders may interpret the same words in different ways in different years. Therefore, workers who change occupations, even though they stay in the same firm, may generate changes in industry codes. This problem was reduced significantly when the survey started confirming preloaded information in 1994.
- The 1979 occupation codes for Job #1 (the CPS job) are only blank placeholders, due to the structure of the job history and "CPS" sections in the initial survey year (1979). The information is contained in the CPS section, but these variables were used as placeholders in anticipation of the future structure of the Employer Supplement.
| Year(s) | Universe |
| 1979-1980 | All current jobs from which R was not laid off in CPS section; other jobs that are government-sponsored part-time or summer jobs, government sponsored jobs for those not in regular school, part of a tax credit program or any other government sponsored program in employer supplement; other jobs R is > 15 years of age & >= 20 hours/week & >= 9 weeks worked since date of last interview in employer supplements |
| 1981 | All current jobs from which R was not laid off in CPS section; other jobs that are government-sponsored part-time or summer jobs, government sponsored jobs for those not in regular school, part of a tax credit program or any other government sponsored program in employer supplement; other jobs >= 20 hours/week & >= 9 weeks worked since date of last interview in employer supplements |
| 1982-1984 | All current/most recent jobs in CPS section; other jobs that are government-sponsored part-time or summer jobs, government sponsored jobs for those not in regular school, part of a tax credit program or any other government sponsored program in employer supplement; other jobs >= 20 hours/week & >= 9 weeks worked since date of last interview in employer supplements |
| 1985 | All current/most recent jobs in CPS section; other jobs that are part of a tax credit program or any government sponsored program in employer supplement; other jobs >= 20 hours/week & >= 9 weeks worked since date of last interview in employer supplements |
| 1986 | All current/most recent jobs in CPS section; other jobs that are part of a tax credit program or any government sponsored program in employer supplement; other jobs >= 10 hours/week & >= 9 weeks worked since date of last interview in employer supplements |
| 1987 | All current/most recent jobs in CPS section; other jobs that are part of any government sponsored program in employer supplement; other jobs >= 10 hours/week & >= 9 weeks worked since date of last interview in employer supplements |
| 1988-1993 | All current/most recent jobs in CPS section; other jobs >= 10 hours/week & >= 9 weeks worked since date of last interview in employer supplements |
| 1994-2000 | All current/most recent jobs; other jobs >= 10 hours/week & >= 9 weeks worked since date of last interview. In 1994 a skip error in this instrument resulted in the occupation codes for some current/most recent jobs being missed (see errata). |
| 2002-2018 | All current/most recent jobs; other jobs >= 10 hours/week & >= 9 weeks worked since date of last interview; self-employed jobs for which the business is not a farm or ranch |
Regularly fielded sections of NLSY79 instruments have collected information on the occupation of respondents' current/last job, jobs since last interview, military job, vocational/technical or government training programs, type of job to which they aspired, and, for those unemployed and out of the labor force, the kind of occupation they were seeking or planned to seek. In addition to this respondent-specific information, data on occupations are also available for other family members, including the spouse and parents of the respondent. Finally, the 1980 school survey collected data on the types of vocational/technical training offered within a respondent's high school.
Verbatim responses to open-ended questions eliciting information on kinds of work or training are entered directly into the survey instrument by the interviewer and subsequently coded using one or more occupational coding schemes. The occupational classification systems listed in Table 1 have been used to code occupations within the NLSY79. Background information on the development of the 1980 classification system and the relationship between the 1970 and 1980 coding categories is available in the 1989 Census publication listed in this section's references.

Comparison to Other NLS Cohorts: NLSY79 young adults were asked open-ended questions on the kinds of work or training they had. For both employee and self-employed jobs, NLSY97 respondents' occupations are coded according to the three-digit census occupational classification system. Freelance jobs that do not qualify as self-employment are coded according to the type of work performed. For the Mature and Young Women, occupation has been coded using 1960, 1980, and 1990 systems in various survey years. The occupations of Older and Young Men were recorded using the 1960 codes for all years; in the final two Older Men surveys, occupation was doublecoded using the 1980 system. For more precise details about the content of each survey, consult the appropriate cohort's User's Guide using the tabs above for more information.

| Survey Instruments and Documentation | Data on occupations have been collected within various topical sections of the NLSY79 questionnaires: "Current Labor Force Status," "Regular Schooling," "Government Training," "Military," "Family Background," and so forth. The Employer Supplements collect occupational information on the type of job performed for a given employer. The separately administered 1980 School Survey was used to collect information on types of vocational and technical courses offered by those schools surveyed. Attachment 3: Industry and Occupation Codes in the NLSY79 Codebook Supplement provides the detailed codes for the Census and DOD classification systems discussed above. The NLSY High School Transcript Survey: Overview and Documentation contains a copy of the school survey that asked about vocational/technical course offerings. |
| Areas of Interest | The census codes for occupations are now consolidated under a single area of interest, "Industry and Occupation." Former areas of interest are also present as secondary areas of interest. |
