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. The 1993 NMFS provisional dataset is located in: ftp://ftp.cdc.gov/pub/Health_Statistics/NCHS/Datasets/NMFS The documentation files for the 1993 NMFS datasets are located in: ftp://ftp.cdc.gov/pub/Health_Statistics/NCHS/Dataset_Documentation/NMFS The survey instruments are located in: ftp://ftp.cdc.gov/pub/Health_Statistics/NCHS/Survey_Questionnaires/NMFS For ease of transmission, the 1993 NMFS provisional data file has been converted to a self-extracting compressed format. To load and expand the data file, do the following: first, copy the compressed file onto your hard drive into an appropriate subdirectory. For example the data files: NMFS93.EXE should be copied into a subdirectory called NMFS93. Then go to that directory and type NMFS93 without the EXE extension. NMFS93.EXE will extract into the file NMFS93.DAT. This file can then be used for processing by PC statistical software packages which utilize ASCII formated input, or uploaded to a mainframe computer for processing. NOTE: The 1993 NMFS is large in size, please use caution as far as disk drive capacity when extracting! 1993 NMFS Provisional Data File SIZE (BYTES) Filename Description of Component File Format Compressed Uncompressed NMFS93.DAT Data file ASCII 5 MB 57 MB The documentation files are in WordPerfect 5.1/5.2 format.
