Data

There are four general categories of data on which qualified researchers may perform statistical analysis inside the secure ARDC.

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

Demographic Data: Censuses and surveys of households and individuals. Most of these datasets are released as public use files, but the versions in the secure RDC are not the public use versions. These restricted RDC versions include a more complete geography (in some cases down to the block). Also, items such as income are often not top coded. Individual identifiers such as name, address, and social security numbers have been removed.

Mixed Data: Includes Longitudinal Employer-Household Dynamics (LEHD) datasets. LEHD uses unemployment insurance records to match employer data with employee data.

Health Data: ARDC provides access to restricted NCHS and AHRQ datasets for approved proposals. To obtain approval, submit a proposal to the appropriate agency.

National Center for Health Statistics (NCHS):

Agency for Healthcare Research and Quality (AHRQ):

 

Public-use Census data are not directly available at the ARDC. However, pending approval from CES, outside data sets may be brought in and matched to non-public Census microdata.
