The multi-component survey focuses on a national representative sample of individuals aged 15 years and over who died in 1993. Forty-nine of the 50 State vital registration areas granted approval to sample their death certificates. The independent vital registration areas of the District of Columbia and New York City also gave permission to sample their death certificates. South Dakota declined to participate in the NMFS due to state law restricting the use of death certificate information. Data for the 1993 NMFS are therefore representative of individuals aged 15 years or older who were residing and died in the United States in 1993, excluding South Dakota. The files listed below comprise the 1993 National Mortality Followback Survey (NMFS) provisional data release. The provisional data files are in ASCII format. The documentation files are in WordPerfect 6.1 format and the survey instruments are in .pdf format. We also included the following files in ASCII format: a SAS input file ; a variable list with labels; sample SAS and SUDAAN programs; a list of anaylsts and their research interests; a list of publication from previous NMFSs;ICD-9 codes; and the Adobe Acrobat Reader 3.0 software.
