2011 Public-Use Linked Mortality Files
Public-use Linked Mortality Files (LMF) are available for 1986-2009 NHIS, NHANES III, 1999-2010 NHANES, and LSOA II and 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 selected decedent records, synthetic data were substituted for the actual date and underlying cause of death. Information regarding vital status was not perturbed.
