Note: All respondents were asked the series of questions of which this variable is a composite. There is still one -2=Inapplicable because, in order to remain consistent in the construction of composite variables, one respondent answered "refused" to each of the constiuent questions (h_emp1, h_emp2, h_empla, h_emp3).

Note: The number of military codes may vary for two reasons:
(1) there is a difference in the coding of military
occupations between the 1970 and 1990 Census, and (2)
an individual may work for the military "industry"
(government) as either a civilian or a member of the
military. These two issues create some confusion in
the assignment of the codes for"military" or
"inappropriate". All cases of this type have been
checked and should be assigned correctly.
(1) The number of military employees may vary between 1970 and
1990 codes for the exact same job. In 1970, all military
employees were assigned to government industry and given a
generic military code (ind = 917, occ = 970-973)regardless of
the exact occupational tasks they performed. In 1990, the Census
basis codes assigned military employees a government industry
(ind = 940-960), but if they held a job that also existed in the
civilian community, they were assigned a non-military occupation
code. The only individuals who received the 1990 generic
military occupation codes (903-905) were individuals who held
jobs that only existed in the military and had no comparable
civilian code.
(2) An individual could work for the military as either a member
of the military or as a civilian. If the individual indicated a
change in jobs within the same employer, one of those jobs could
be listed as a military occupation, while the other may be listed
as civilian. There are cases where the first job within an
employer spell was military and the last job within the same
spell was civilian, as well as the reverse situation.

Note: The 1990 Major Industry categories are selected
to resemble the 1970 categories, but individual
industries which may have changed category between
1970 and 1990 (for example, US Postal Service)
keep their 1990 major industry designation. No
attempt was made to reconcile these cases.

Note: See Appendix E - COR681 for detailed coding instructions.

Note: The 1990 Major Occupation categories are selected
to resemble the 1970 categories, but individual
occupations which may have changed category
between 1970 and 1990 (for example, Actors and
Directors) keep their 1990 major industry
designation. No attempt was made to reconcile
these cases. The large number of such cases makes
direct comparison between 1970 and 1990 Major
Occupation categories unadvisable. For a list of
all such individual changes, see Kubitschek 1986
(Center for Demography Working Paper 86-6).

Note: See Appendix E - COR681 for detailed coding instructions.

Note: There is an implied decimal point one place to the left of the
right most digit.

Note: Military occupations (903-905) were not assigned a code in cor680.
They have been assigned a code of -4 in this routine

Note: The 1989 Nakao-Treas prestige rating is the
percentage of respondents in the 1989 NORC General
Social Survey who ranked an occupation in category 5
or above on a 9-point scale. See Appendix E--COR 683
for details and a recommended transformation of this
variable.

Note: See Change Notice #21 for information about the 9/00 update.

Note: There is an implied decimal point one place to the left of
the right most digit.

Note: The 1990-basis occupational education score is the
percentage of persons in the 1990 Census in an occupation/
industry/class-of-worker category who completed
one year of college or more. See Appendix E--
COR 639 and COR 684 for details, and a recommended
transformation of this variable.

Note: Consistent with 1990 Census procedures, civilian occupation
codes were assigned to military personnel if they described
civilian occupational activities. Therefore, it is possible
to assign a code for those individuals on this variable.
Individuals in the military who only described military
occupations were assigned the military occupation codes and
coded inappropriate on this variable.

Note: See Change Notice #21 for information about the 9/00 update.

Note: There is an implied decimal point one place to the left of
the right most digit.

Note: The 1990-basis occupational earnings score is the
percentage of persons in the 1990 Census in an occupation/
industry/class-of-worker category who earned
at least $14.30 per hour in 1989. See Appendix
E--COR 639 and COR 684 for details, and a recommended
transformation of this variable.

Note: Consistent with 1990 Census procedures, civilian occupation
codes were assigned to military personnel if they described
civilian occupational activities. Therefore, it is possible
to assign a code for those individuals on this variable.
Individuals in the military who only described military
occupations were assigned the military occupation codes and
coded inappropriate on this variable.

Note: Full-time means 35 hours or more per week.
