58:40840 Bowles, Gladys K.; Tarver, James D.; Beale, Calvin L.; Lee, Everette S. Net migration of the population by age, sex, and race, 1950-1970 [MRDF]. Pub. Order No. ICPSR 8493. [1990?]. Inter-University Consortium for Political and Social Research [ICPSR]: Ann Arbor, Michigan. In Eng.
"These data files contain estimates of net migration by age, race, and sex for United States counties from 1950 to 1960 and from 1960 to 1970. These estimates were derived from census-survival ratio forward methods, adjusted to be consistent with vital statistics by county....Data on births according to sex and race are presented as well as total population according to age. Net migration estimates and net migration rates for each category also are included." Data are in two files; each is rectangular in structure and has a length of 7,604 records.

58:40841 Keeble, Gregory. Report on survey of computer usage in statistics and planning offices in the SPC region, 1990. 1992. v, 23 pp. South Pacific Commission: Noumea, New Caledonia. In Eng.
Results are presented from a 1990 survey of computer usage in statistical and planning offices in 21 South Pacific countries and territories. "Since the last survey in 1987, there has been a phenomenal growth in the numbers of computers and software used in statistical offices in the Pacific. Computerisation of statistical collections and the use of application software for statistical and demographic analysis in both planning and statistics offices will continue to expand in the foreseeable future." The growth of computer linkage through network systems is noted.

"The 1986 National Mortality Followback Survey (NMFS) is the first National Center for Health Statistics (NCHS) mortality followback study since the 1966-1968 survey of the same name....The 1986 NMFS supplements characteristics of mortality found in the routine vital statistics system by collecting information from death certificate informants or other knowledgeable relatives, and from health care facilities that were used by decedents in the last year of life. The death records provide demographic data on the decedent and information on the circumstances of death...and use of medical facilities in the preceding year. Additional issues that were addressed...were...risk factors associated with premature death, socioeconomic status and mortality, and reliability of selected items reported on the death certificate....This hierarchical data collection has two levels of records. The first level has approximately 342 variables and one record per case for each of the 18,733 decedents in this study....The second level contains data from health care facilities....Each decedent may have up to six facility records....There are 35,757 total records in the data set." Information on any data analysis restrictions can be obtained from ICPSR.
