The Rocky Mountain Research Data Center (RMRDC) provides access to microdata from federal statistical agencies for approved research projects (see proposal guidelines). These data come primarily from the U.S. Census Bureau and not a regular part of the Census Bureau data dissemination program. A detailed listing of available restricted data sets is provided at the CES Data link which includes links to documentation and survey sponsors. Further information on the contents of the data sets listed can be found at the Census web page ( Researchers need to consult with an RDC Administrator on availability of particular data sets before writing research proposals.

Four groups of data sets are available:

Demographic Data: Censuses and surveys of households and individuals. These data are not public use files. They include complete geography (in many cases down to the block). Items such as income are not top-coded. Individual identifiers such as name, address, and social security numbers are not included.

Economic Data: Censuses and surveys of business establishments and firms. With very few exceptions, no public use files exist for these surveys.

Linked Business and Household Data: Uses modern statistical and computing techniques to combine federal and state administrative data on employers and employees with core Census Bureau censuses and surveys while protecting the confidentiality of people and firms that provide the data.

Health Data: The RMRDC enables access to restricted data from the National Center for Health Statistics (NCHS) and the Agency for Healthcare Research and Quality (AHRQ). A detailed description of the NCHS restricted data is provided here: NCHS Restricted Data; how to gain access through the RDC can be found at Descriptions of the differences between NCHS RDC confidential data and public use versions of the data are given in this linked chart. A summary of NCHS surveys and data systems can be found here. A detailed description of AHRQ's MEPS-IC file and how to gain access through the RDC can be found on AHRQ's RDC web page. An informative health related research discussion paper can be found here: Health Related Research Using Confidential U.S. Census Bureau Data.

Other Restricted Data: See the list of other federal statistical agencies partnering to provide data to the RDC network.
