Older Men

This section overviews the raw and created industry variables available for the Older Men cohort. Open-ended questions, e.g., "What kind of business or industry is/was this?", were included within various sections of the questionnaires during each interview. Verbatim responses to this question were coded by Census personnel using three-digit codes from the 1960, and for select variables, the 1980 classification systems (Census 1960, 1980). (See Attachment 2 in Codebook Supplement). Two- and one-digit edited versions of these raw variables are available for most survey years. An extensive discussion of Census/CHRR editing and creation procedures that affect the industry variables can be found in the User Notes at the end of this section.

Data were collected during each survey year on the industry of a respondent's current or last job. The 1967-69, 1976, and 1981 interviews also gathered information on the industry of the longest intervening job held between yearly survey dates or during the past 12 months. The 1971 questionnaire included a detailed work history section that allowed collection of industry information on up to seven intervening jobs. Retrospectives in 1976, 1981, and 1990 collected industry information for the longest job held between 1971 and 1976, 1976 and 1981, and 1983 and 1990. The 1973-76, and 1981 surveys elicited information from those respondents who were unemployed at both the current and previous interviews on the industry of any job held between survey dates. During certain interview years, questions about the industry of a second or dual job, a hypothetical job or business, or a retirement job were fielded. The 1981 and 1990 surveys included questions on the longest job held by the respondent's wife between 1976 and 1981 or by the respondent's widow between 1983 and 1990. Information was collected during the 1990 interviews from the widows of deceased respondents on the industry of the last job held by the respondent.

Edited variables from the Occupation & Industry (O & I) Rewrite are present for each survey year that provide one-, two-, or three-digit versions of the raw current/last job variables. The 1960 Census codes were used exclusively up through the 1981 interview to code industry information; beginning in 1983, the current/last job variables were doublecoded with the 1960 and 1980 classification systems. Several versions of the current/last job variables, e.g., edited and unedited, collapsed and noncollapsed, are also available. See the User Notes for additional information.

1 This number reflects the total number of interviews conducted during 1990. Excluded from this table is industry information on 722 respondents for whom neither a respondent nor widow/proxy interview was conducted in 1990. Frequencies in the "Total" column do not equal the sum of the respondent and widow/proxy interview numbers due to the exclusion of 183 interviewed sample persons who do not have valid values on 'Employment Status Recode,' the variable used to determine labor force status.

2 For the 2206 respondents whose widow or proxy was interviewed during 1990, the industry code reflects the one provided by the respondent during a previous interview. Information collected during 1990 from a widow/proxy on the industry of the respondent's last job is available for only a small number of respondents; values are not included in this table.

Universe: Respondents who were working or with a job but not at work for whom information on the industry of current employer was available. Industries were coded with the 1960 Census classification system.

Survey Instruments & Documentation: Questions on industry are found in the regularly fielded "Current Labor Force Status," "Work Experience," Work History," and/or "Retrospective Work History" and the special 1966 "Attitudes Towards Work" and 1971 "Plans for the Future" sections of the Older Men questionnaires. Additional industry information was collected using the "Widow's Work Experience" and "Information on Deceased Sample Persons" sections of the 1990 widow's questionnaire. Part One and Appendix H of Attachment 2: 1960 & 1980 Census of Population Industrial & Occupational Codes provide listings by industry of the relevant one-, two-, and three-digit codes. Appendix 31 presents a partial derivation for the 1990 collapsed industry variables. Derivations for the collapsed variables from previous years can be found in the documentation for the class of worker variables. Attachments and appendixes are found in the Codebook Supplement.

User Notes

Substantive differences exist between a number of similarly titled occupation, industry, and class of worker variables present in the data files. One set of raw variables relating to the respondent's current job is derived from responses to questions found within the "CPS" section of each questionnaire. Additional versions of this set of variables are created using the two different procedures described below.

(1) An Occupation & Industry (O & I) Rewrite creates a set of seven "backfilled" or summary variables that enable researchers to identify the last occupation, industry, or class of worker status of all respondents who were interviewed in a given year whether or not they were currently working. Values utilized are those from the job in which the respondent was employed the week before the interview or "backfilled" values from the job that was current at the last time the respondent reported employment. Although the industry associated with an intervening job might technically be a respondent's most recent industry affiliation, the O & I program is not designed to pick up information from such jobs. All O & I variables are classified utilizing the 1960 Census codes. Titles for this set of O & I Rewrite variables appear below.

Occupation & Industry Variables from the O & I Rewrite

Variable Title Version Question #
Class of Worker at Current or Last Job Collapsed  
Occupation of Current or Last Job 3-digit  
Occupation of Current or Last Job Duncan Index [Always Blank--
Occupation of Current or Last Job 1-digit Created Variables]
Industry of Current or Last Job 3-digit  
Industry of Current or Last Job 2-digit  
Industry of Current or Last Job 1-digit  

O & I Rewrite variables can be differentiated from non-backfilled variables by (1) the absence of a question number in the documentation that identifies the source of the variable; or (2) an assignment of a reference number that places an O & I variable among the created variables series appearing at the end of a given survey year's variables. In order to assist researchers identify these variables, an attempt has been made to append the word "collapsed" to the end of the O & I variable titles of select cohorts. This convention has been applied as follows: (1) all O & I 'Class of Worker' variables in all four cohorts for all survey years have the word "collapsed" appended to the variable titles and (2) the O & I occupation and industry variables from the 1990 Older Men surveys are identified with the word "collapsed." O & I Rewrite variables for the Young Men can only be identified using the question/reference number assignment conventions discussed above. Users unfamiliar with NLS assignment conventions should refer to chapter 3 of this guide.

It is not clear why the O & I Rewrite variable titles are identical to those of the occupation/industry/class of worker variables. It may have been that these O & I rewrite variables were originally private variables intended only for use by in-house CHRR researchers and subsequently released to the public.

(2) An editing procedure begun by Census in the 1980s cleans items from the "CPS" section of the questionnaire in order to create the 'Employment Status Recode' variables. The ESR variables were originally generated by Census with no cleaning or editing of the items from the "Current Labor Force Status - CPS" sections of the questionnaire. In the mid-1980s, reoccuring problems with the program that created ESR forced Census to create edited "CPS" items. Both unedited and edited versions of these items are sent to CHRR and released to the public. Edited variables are identifed with either the word "EDITED" or the abbreviations "EDT" or "E" appended to the variable title. Edited versions of these variables will have fewer cases than the unedited versions. When looking at patterns over time, users may wish to use the set of unedited versions.
