Date of Collection:
Unit of Observation:
High school seniors in the contiguous United States.
Data Collection Notes:
(1) Percentage distributions provided in the codebook
were generated using full weights, which are not available on the
public use files. Therefore, these results cannot be replicated using
the public use files. The differences between results produced using
the full weights and those produced using the sampling weights
available on the public use files are estimated to be below 1
percent. (2) To protect the confidentiality of respondents, all
variables that could be used to identify individuals have been
collapsed or recoded on the public use files. These modifications
should not affect analytic uses of the public use files.
MTF does not release detailed geography codes in its public use files because of the disclosure risk it would cause. The MTF sample is drawn to generate representative samples of the four Census Bureau regions of the country (Northeast, Midwest, South, and West), but it does not generate representative samples of smaller geographic areas such as states, counties, or cities. For additional information about data that is withheld from the public use files please contact MTF directly at firstname.lastname@example.org.
Multistate area probability sample design involving three
selection stages: (1) geographic areas or primary sampling units
(PSUs), (2) schools (or linked groups of schools) within PSUs, and (3)
students within sampled schools. Of the 74 PSUs, 12 were selected with
certainty and 62 were selected with probability proportionate to size
based on the size of the senior class. In schools with more than 400
seniors, a random sample of seniors or classes was drawn. In schools
with less than 400 seniors, all seniors were asked to participate.
Each school was asked to participate for two years, so that each year
one-half of the sample is replaced. Schools refusing participation
were replaced with similar schools in terms of geographic location,
size, and type of school (e.g., public, private/Catholic,
Each of the six parts contains a weight variable, V5. They
were originally varied by school but were modified to protect
respondent confidentiality. Users should use the weight variable for
all analyses, the results of which will differ slightly from published
data tables that used original data.
Mode of Data Collection:
The participation rate among schools has been
between 66 and 80 percent since the inception of the study. The
overall student response rate for 1981 was 81 percent.
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:
