  • Longitudinal Data Dictionary (LDD): The LDD is an extensive set of tables, one for each Record Type in CHS.  Each table contains all questions asked (at any year) on that record and lists the variable names corresponding to the question for each year the question was asked. The LDD is a Word document and can be downloaded directly or as a zipped file.
