2015 Public-Use Linked Mortality Files

Public-use Linked Mortality Files (LMF) are available for 1986-2014 NHIS.  The files include a limited set of mortality variables for adult participants only. The public-use versions of the NCHS Linked Mortality Files were subjected to data perturbation techniques to reduce the risk of participant re-identification. For select records, synthetic data were substituted for the date of death and/or underlying cause of death. Information regarding vital status was not perturbed.

Public-use 2015 Linked Mortality Files for NHANES III and 1999-2014 NHANES are forthcoming.
