Introduction

The 1993 National Mortality Followback Survey (NMFS) is the sixth mortality
followback survey conducted by NCHS.  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.

Overview of the File Structure

The 1993 National Mortality Followback Survey (NMFS) public use provisional
data file contains 22,957 records with a length of 2,623.  Each record contains
data for a single decedent.  The contents of the file are described in detail
in the file documentation which also contains question text, and weighted and
unweighted frequencies for each variable.   Each record is divided into four
parts.  These parts contain control and sampling information, death
certificate data, proxy respondent questionnaire data, and multiple cause of
death data.  Each part is further sub-divided into groups of related
variables.
