The Child Development Supplement (CDS) was created to provide researchers with comprehensive,
nationally representative, longitudinal data of children and their families with which to study
the dynamic process of early human capital formation. More information about the study and data
are provided in the CDS User Guides.
The time diaries are one of the unique features of the CDS survey design. With the assistance of
their primary caregiver when needed, CDS children completed a set of time diaries as part of their
involvement in the overall CDS data collection effort: one diary for a randomly selected weekday
(Monday-Friday) and another for a randomly selected weekend day (Saturday or Sunday). The time
diaries provide detailed accounting of the type, number, duration, and location of activities
during sampled 24-hour days, beginning at midnight. The time diaries additionally collected
information on the social context of the activity by specifying with whom the child was doing
the activity and who else was present, but not engaging, and the names of television shows watched
by the children.
The Center for Research on Interactive Technology, Television and Children (CRITC) at the University
of Texas at Austin coded the television programs that were reported in the 1997 and 2002 CDS Time
Diaries (CDS I-II). The television coding manual describes the data structure and coding procedures
as can be found in Appendix E of the CDS-II

The data file is structured at the activity level. There is one record per media activity with a valid content code for each of the weekday / weekend diaries for each child for each wave of data collection (1997 data and 2002 data are kept in separate files). Key identifier variables that will help you link the media codes back to the main time diary activity file are as follows (these are wave specific).
There are 16 variables generated by the media coding project: (1) Format (TD97M09, TD02M09); (2) Intended Audience (TD97M10, TD02M10); (3) Character Age (TD97M11, TD02M11); (4) Genre (TD97M12, TD02M12); (5) Comedy (TD97M13, TD02M13); (6) Science Fiction, Fantasy or Supernatural/Paranormal (SF/F/SP) (TD97M14, TD02M14); (7) Curriculum (TD97M15, TD02M15); and (8) Violence (TD97M16, TD02M16) of each television program. Please consult the codebook for a description of these variables for each wave.
