The National Center for Health Statistics (NCHS) is pleased to offer downloadable public-use data files through the Centers for Disease Control and Prevention's (CDC)/FTP file server.  Users of this service have access to data sets, documentation, and questionnaires from NCHS surveys and data collection systems. Downloading instructions are available in "readme" files.

Public-use data files are prepared and disseminated to provide access to the full scope of the data.  This allows researchers to manipulate the data in a format appropriate for their analyses.  NCHS makes every effort to release data collected through its surveys and data systems in a timely manner.

Descriptions of NCHS data systems and activities are found in the section Surveys and Data Collection Systems.  Public-use data files that are not listed below can be obtained through other sources.  Ordering instructions and the various formats available (e.g., CD-ROM and data tape) are provided in the Electronic Products web pages.

Users of NCHS public-use data files must comply with data use restrictions to ensure that the information will be used solely for statistical analysis or reporting purposes.
