Surveys which use lists related with the vital statistics to sample individuals for the further information. For instance, the 1988 National Mortality Follow back Survey sampled death certificates for the year 1986 decedents 25 years or older were filed in the USA. Information was then sought from next of kin or some other person familiar with decedent, and from health care facilities used by decedent in the last year of life. Information was achieved by emailed questionnaire, or by telephone or by the personal interview. One more instance of such a survey is the 1988 National Maternal and Infant Health Survey, live birth component of which sampled birth certificates of the live births in the USA. Mothers matching to the sampled birth certificates were mailed a questionnaire. The sample designs of this kind of survey are usually quite easy, including a stratified selection of the individuals from a list frame.
