• Description:
  Background—Linking data is a powerful mechanism to provide policy-relevant information. The National Center for Health Statistics’ Data Linkage Program produces linked mortality files (LMFs) for research by linking data from the National Center for Health Statistics’ surveys, including the National Health Interview Survey (NHIS), to mortality data from the National Death Index. Assessing the accuracy of the linked data is an important step in ensuring its analytic use. This report compares the cumulative survival probabilities estimated with the 2006–2018 NHIS LMFs to those from the annual U.S. life tables.
  
  Methods—Cumulative survival probabilities for 13 annual NHIS LMF cohorts were derived using the Kaplan–Meier product limit method, and cumulative survival probabilities were computed for the U.S. population using information from annual U.S. life tables. The survival probabilities were calculated at various lengths of follow-up for each age-race-ethnicity-sex group of each NHIS cohort and for the U.S. population.
  
  Data sources—Survey data from 2006 through 2018 NHIS sample adults were linked to death certificate data from the National Death Index. The survival probabilities of each NHIS cohort were compared with the corresponding probabilities of the U.S. population using the U.S. life tables.
  
  Conclusion—Overall, the survival probabilities estimated with the NHIS LMFs were similar to those for the U.S. population. Thirty-four statistically significant differences were observed between the NHIS LMF estimates and corresponding U.S. life tables across all age groups, sex and race and ethnicity categories, and followup intervals. By race and ethnicity category, non-Hispanic Black adults had 14 statistically significant differences in survival probabilities, non-Hispanic White adults had 11 statistically significant differences, and Hispanic adults had 9 statistically significant differences. The results of this analysis can be used as a resource to support empirical findings and inference for mortality studies using LMFs.
