|Title:||Vital Statistics: Marriage Detail, 1970 [United States]|
|Primary Investigator(s):||United States Department of Health and Human Services. National Center for Health Statistics (NCHS)|
|Abstract:||The marriage detail files include all marriages occurring in states that meet reporting criteria for inclusion in the marriage-registration area, except for California unlicensed marriages. Marriages occurring outside the marriage-registration area are not included.|
Data are obtained from certificates of marriages occurring in each registration state. Records of each state in the marriage-registration area were sampled at one of five sampling rates used in processing 1968-95 data. Data are weighted, based on the sampling fraction of the reporting state.
The files include one record for each marriage in the sample. Marriage certificate numbers are not on the tapes. NCHS does not distribute certificates, files, or indexes with identifying information for marriages.
Items included on the files are data year, age, date of marriage, date last marriage ended, education, interval from last marriage to present marriage, number of this marriage, previous marital status, race, state of birth, state of residence, type of ceremony, and record weight. Most of these items are included across the 1970-1988 interval. Years before and after that have less information. The collection of marriage/divorce detail information was suspended in January 1996.
|Universe:||Marriage data are classified by state of occurrence. From 1968 through 1970, the marriage-registration area included 39 States and the District of Columbia; two additional states were included in 1971; one additional state was included in 1979 and there was no further change until 1995 when one state dropped out of the registration area. Data are not classified for counties or cities.|
