Active Force: An umbrella term used to refer to the regular Army, Navy, Marines, and Air Force branches of the Armed Forces as a group. The Reserve and Guard components are not included.

AFDC: Aid to Families with Dependent Children.

AFQT: See Armed Forces Qualification Test

AFSC: See Air Force Specialty Codes

Air Force Specialty Codes: An alphanumeric jobs/skills classification system for the Air Force and Air Force Reserves that describes the specific job a person is trained for or assigned to in those branches of the military. (See also DOD-3-Digit.)

Annuities: See Pensions

Armed Forces Qualifications Test: The AFQT determines general aptitude for enlistment in the Armed Forces. Two methodologies of calculating AFQT, developed by the U.S. Department of Defense, have been used to produce two AFQT variables in the NLSY79: R06182. (AFQT80) and R06183. (AFQT89). R06182. is the AFQT percentile score created from the procedures in use in 1980 and consists of the sum of the number of correct scores for the following sections of the ASVAB: arithmetic reasoning + word knowledge + paragraph comprehension + 1/2 (numerical operations). R06183. is the AFQT percentile score based on new procedures established in 1989 and is created in the following manner: (1) compute a verbal composite score by summing the word knowledge and paragraph comprehension raw scores; (2) convert subtest raw scores to standard scores for verbal, math knowledge, and arithmetic reasoning; (3) multiply verbal by 2; (4) sum the standard scores for verbal, math knowledge, and arithmetic reasoning; and (5) convert the summed standard score to a percentile. See the Addendum to Attachment 106 for tables used to convert raw scores to standard scores and percentiles.

Armed Services Vocational Aptitude Battery: The ASVAB is a vocational aptitude test that determines areas of competency in the following 10 areas: general science, arithmetic reasoning, word knowledge, paragraph comprehension, numerical operations, coding speed, auto and shop information, mathematics knowledge, mechanical comprehension, and electronics information. The ASVAB was administered to more than 94 percent of the NLSY79 in order to establish new norms for the population of potential enlistees. The ASVAB is used by Department of Defense (DOD) researchers to improve the ways training and duty assignments are made for those who enter the Armed Forces. It is also used by vocational guidance counselors to assess vocational interest and preparation of students. Standardized scale scores and standard errors are available for each section.

Cohort: A cohort is a group sharing similar characteristics at a particular point. The cohort selected for the NLSY79 includes 12,686 youth who were age 14-21 on December 31, 1978 (born between January 1957 and December 1964), either civilians residing in the 50 United States (11,406 sample members) or non-civilians on active duty in the U.S. Armed Forces in September 1978 and born between January 1957 and December 1961 (1,280 sample members).

Commissions: See Tips

Comprehensive Employment and Training Act: Originally enacted in 1973, CETA superseded the Manpower Development and Training Act of the 1960s. CETA was administered by the U.S. Department of Labor and was designed to provide employment and training opportunities for the economically disadvantaged, under-employed, and unemployed. Under its several titles, CETA provided a variety of services including classroom and on-the-job training, work experience, subsidized jobs with public and private sectors, basic education, and support services such as counseling. The various programs were planned and operated by state and local governments with Federal funding and oversight. CETA legislation expired in the fall of 1982 and was replaced by the Job Training Partnership Act (JTPA).

CPS: See Current Population Survey

Current Population Survey: Monthly interviews conducted by the Census Bureau with a scientifically selected sample of households in several hundred sample areas throughout the U.S. The primary purpose of the CPS is to collect up-to-date information about the number of persons in the country who are employed, unemployed, or not in the labor force in a specific survey week. The CPS is the source of the monthly official unemployment rate figures. CPS questions included in the NLSY79 surveys are the same as the CPS questions used to determine employment status and are administered as closely as possible to the method used by the Census Bureau so that findings are comparable.

Delayed Entry Program: A program that allows a person to enlist in the military and then report for active duty at a later time (as many as 365 days later.) Individuals enlisting through this program are sworn into their military branch on two occasions: once at the time that they enlist through DEP and a second time when they actually begin active duty. DEP enlistees do not always report for active duty and can be guaranteed, in writing, the type of training and the location that they want.

DEP: See Delayed Entry Program

Dictionary of Occupational Titles: This occupational directory was developed by the Department of Labor as a comprehensive classification system for occupations.

The index scores are based on education and income distribution ratings and range from 0 to 97. (See Otis Dudley Duncan. "A Socioeconomic Index for all Occupations." In: Occupations and Social Status, Reiss, Jr., A.J., et.al., New York: The Free Press of Glencoe, 1961).

Environmental Variables: County and state codes are assigned for all geographic locations according to the Federal Information Processing Standards (FIPS-5). The codes for the respondent's current residence at each interview date are then matched with the 1972, 1977, 1983, 1988, and 1994 City and County Data Books (depending on survey year) to obtain characteristics of the county such as population size, crime statistics, industrial diversification, etc. (see specific survey year). These data are available to researchers willing to insure their confidentiality.

Beginning with the 1982 interview, the industry of the respondent's current or last job was also coded using the 1980 codes.

Information Sheet: An Information Sheet, which lists pertinent informational items about the respondent that were collected during the previous interview is provided to NORC interviewers.

The automated CAPI instruments access it automatically to drive the survey.

Int: An abbreviation for interview.
