The HHS Directory of Health and Human Services Data Resources is a compilation of information about virtually all major data collection systems sponsored by the U.S. Department of Health and Human Services (HHS). The Directory was developed under the auspices of the HHS Data Council, which serves as the department's senior internal data policy body and advises the Secretary on a variety of data policy issues. The directory updates and expands upon earlier editions. Additional data systems are included in this update, and more extensive information about each data system is provided, including links to relevant websites.
The Directory of Health and Human Services Data Resources is intended for policymakers, administrators, researchers, and the public as a reference document on data and statistical resources within HHS. This document is available on HHS's home page on the Internet at http://aspe.hhs.gov/datacncl/datadir.
The Directory of Health and Human Services Data Resources was designed to include data resources with current utility, or the potential for use by a wide variety of audiences. Databases from continuing departmental data collection projects or program administrative and evaluation activities that met the criterion of broad utility were included in the directory. Such data projects and systems included recurring surveys, public health surveillance systems, disease registries and programmatic data systems sponsored by HHS. Databases from one-time studies or data collections were also included when the data may have broad interest.
In general, data from the systems and projects described in this directory are available in published and aggregate form. In some cases, public use microdata files are available for research and statistical purposes as well, often subject to data use agreements. All records in these public use files have been anonymized. The confidentiality of identifiable information held by HHS agencies is protected by the Privacy Act. In addition, most of the major research and statistical databases described in this directory are governed by special federal confidentiality statutes, similar to the Census Statutes, that strictly forbid the disclosure of identifiable information.
The table on the following page defines in more detail the headings used for information collection for the Directory of Health and Human Services Data Resources.
