Persons in Group Quarters were included in the 1990 and 2000 decennial census long
forms.
That is why it is important to understand the difference in “universes”:
Total persons and Persons in Households.
Total persons INCLUDES people in group quarters.
Persons in Households EXCLUDES people in group quarters.
As a reminder, questions about vehicle availability is asked of HOUSEHOLDS, therefore only
available to tabulate for households.
Means of transportation to work is asked of PERSONS.

I don't think there's any question that dorms are non-institutional GQ.

Are there any list/table of “institutional” GQs? This may help resolve this question. A
broad definition of “institution” may be interpreted differently by different people.

Subject: [CTPP] Question about Inclusion of Students in JTW Data
A question has come as to whether employed students living in dormitories are included in
the 2006-10 CTPP JTW tables.
Researching the question, I found the following on p. 66 of the 2013 ACS Subject
Definitions document, under the definition of employed persons
(
http://www2.census.gov/programs-surveys/acs/tech_docs/subject_definitions/2…):
Beginning in 2006, the population in group quarters (GQ) is included in the ACS. Some
types of GQ populations have employment status distributions that are different from the
household population. All institutionalized people are placed in the “not in labor force
category.” The inclusion of the GQ population could therefore have a noticeable impact on
the employment status distribution. This is particularly true for areas with a substantial
GQ population. For example, in areas having a large state prison population, the
employment rate would be expected to decrease because the base of the percentage, which
now includes the population in correctional institutions, is larger.
I interpret this to mean that dorm residents, as noninstitutionalized group quarters
residents, are included in CTPP statistics but want to confirm that my understanding is
correct.
My follow up question concerns the 1990 and 2000 JTW tables. Were employed dormitory
residents (ie, noninstitutionalized group quarters residents) included in those
statistics? My recollection is that is not the case but I want to confirm that is
correct.
Thanks
