NHANES III Linked Mortality Public-use File

 

Data File Description

The updated NHANES III Linked Mortality Public-use File provide mortality follow-up data from the date of the NHANES III survey participation (1988-1994) through December 31, 2006. The public-use version of the NHANES III Linked Mortality File was subjected to data perturbation techniques to reduce the risk of respondent re-identification while increasing the accessibility of NCHS micro data files. Synthetic data was substituted for the actual date and underlying cause of death data for selected decedent records. Information regarding vital status was not perturbed. The restricted-use version of the NHANES III Linked Mortality File is not subjected to data perturbation techniques. NCHS has conducted a comparative analysis [PDF - 116 KB] of results obtained from the public-use and restricted-use NHANES III Linked Mortality Files.
