The public-use National Health Interview Survey linked mortality files: methods of reidentification risk avoidance and comparative analysis.

In 2004, NCHS updated the mortality follow-up for the 1986-2000 National Health Interview Survey (NHIS) years, which because of confidentiality protections was made available only through the NCHS Research Data Center.

To demonstrate the comparability between the public-use and restricted-use v
