National Center for Health Statistics announces linkage of disparate health survey files

The National Center for Health Statistics (NCHS) of the Centers for Disease Control and Prevention (CDC) is pleased to announce that NCHS has updated the linkage of the 1994-2005 National Health Interview Survey (NHIS) to benefit history data from the Social Security Administration (SSA). The updated NHIS Linked SSA Files provide SSA benefit data through December 31, 2007.The linked files combine health and socio-demographic information from NHIS surveys with benefit information from SSA's Old Age, Survivors and Disability Insurance (OASDI) and Supplemental Security Income (SSI) benefit programs, resulting in unique population-based information resources that can be used to support a wide array of epidemiological, health services, and health policy research.

Due to confidentiality requirements, access to the NHIS Linked SSA Files is available only through the NCHS Research Data Center (RDC). For more information on the updated NHIS Linked SSA files, please visit:

The NCHS RDC offers on-site and remote access capabilities. Interested researchers must submit an application to the NCHS RDC. For more information on the NCHS RDC  visit:

To assist researchers interested in accessing the restricted-use NHIS Linked SSA files, NCHS has created publicly available NHIS Linked SSA Feasibility Study data files that can be downloaded directly from the following website:

http://www.cdc.gov/nchs/data_access/data_linkage/ssa/ssa_feasibility.htm

The NHIS Linked SSA Feasibility Study data files provides information about which survey respondents have been successfully linked to SSA data and which types of benefit records will be available for each linked survey respondent.  This file should serve as a tool for researchers interested in assessing potential sample sizes and feasibility of pursuing a RDC application. It is important to note that the feasibility study
files do not contain any specific information about SSA benefits.
