This manual provides documentation and guidance for users of the public release data files (adult file and course file) for Adult Education (AE) component of the 1991 National Household Education Survey (NHES:91). The NHES:91 was a random-digit dial telephone survey developed by the National Center for Education Statistics (NCES) and conducted by Westat, Inc. Data for the full-scale study were collected between late January and early May of 1991. The collection of data directly from non-institutional samples of individuals is a new initiative for the NCES and holds the promise of greatly enhancing the scope of issues covered by the NCES by providing information on many current issues in education. There were two general components of the NHES:91. The first of these was the Early Childhood Education component, concerned with the experiences of 3- to 8-year-old children. The second component pertained to the participation in adult education of persons aged 16 years and older. The introductory chapter, of the manual provides overviews of these components as well as information about the purpose of the study, the sample design, and data collection and data processing procedures. Following the introduction (chapter 1) the other chapters are: (2) "Description of Data Collection Instruments"; (3) "Sample Design and Implementation"; (4) "Data Collection Methods and Response Rates"; (5) "Data Preparation"; (6) "Guide to the Data Files and Codebooks"; and (7) "Data Anomalies." Six tables and four figures supplement the text. Six appendixes, comprising the greater part of the document, provide the NHES:91 questionnaire, adult file and course file variable lists, SAS and SPSS-X control cards, guidelines for using SAS and SPSS-X, SAS codes for composite variables, and adult file and course file codebooks.
