Guidelines on use

Recipients of data files are asked to follow NCHS guidelines on their use. Any published material derived from the data should acknowledge NCHS as the source and should include a disclaimer that credits any analyses, interpretations, or conclusions reached by the author (recipient of the file) to that author and not to NCHS, which is responsible only for the initial data. Users who want to publish a technical description of the data should make a reasonable effort to ensure that the description is consistent with that published by NCHS.

Guidance on how to approximate the sampling variances of the estimates compiled by NCHS and information about the magnitude of the nonsampling errors are provided with the documentation that accompanies the diskettes, or CD-ROMs. Users are urged to include appropriate sampling error statements in all data they publish. Information is also available on biases, and users should include statements on the biases known to effect the data in any reports they may publish.
