References to data of demographic interest that are stored in machine-readable form. All MRDFs coded under this heading are cross-referenced to specific subject categories as appropriate. Articles concerned with the availability of MRDFs are also included.

54:30800 Conning, Arthur; Silva, Ari. Microcomputer access to geographically disaggregated population and housing census data for migration studies via the REDATAM system. [Acceso a traves de microcomputadores a datos censales de poblacion y vivienda geograficamente desagregados para estudios de migracion usando el sistema REDATAM.] Revista del CIM sobre Migraciones en America Latina/ICM Latin American Migration Journal, Vol. 6, No. 1, Apr 1988. 7-34 pp. Santiago, Chile. In Eng; Spa.
The authors describe "the interactive, user friendly, REDATAM system [that] was created to solve the problem of providing small-area population and housing census information by using a microcomputer to store the microdata (the values of each variable of each individual) of an entire census, thereby permitting any set of variables to be tabulated for any area often down to city blocks or smaller." Particular attention is paid to the system's suitability for handling migration data. "Facilities offered by the system, include geographic selection, grouping of geographic areas, self-documented databases, interactive and batch processing, calculation of derived variables, hierarchical processing, generation of sub-databases, use of weighting factors, production of files for export to other packages, storage of results and password protection." The focus is on REDATAM databases available for Latin America and the Caribbean.

54:30801 Field, Niel C. Modeling demographic change: a versatile population projection package for the microcomputer. Operational Geographer/Geographie Appliquee, No. 10, 1986. 35-9 pp. Montreal, Canada. In Eng.
The author describes a software package developed for demographic analysis on microcomputers. "It is a single-region cohort survival model based on 5-year age-sex groups and 5-year projection intervals. The program operates with user-supplied data inputs in the form of initial age-sex specific fertility rates, mortality rates and net migration values. Through a system of coefficients the user can schedule changes in the three growth factors (fertility, mortality, and net migration) in any or all of the 5-year projection intervals." Directions for program use and availability are included.

"This report is a brief overview of a workshop on microcomputer-based software for population and development planning sponsored by the Committee on Population. The workshop, held February 10-13, 1987, at the National Academy of Sciences, was an attempt to provide a forum for producers and users of population-related software to review the available programs....This report does not attempt to assess in any detailed way the underlying demographic, statistical or programming strengths and weaknesses of the various programs, nor does it document all the exchanges that took place. It does, however, present an inventory of available software packages for analyses of demographic processes and the interrelation of those processes with economic development. The packages reviewed are categorized as demographic, sectoral, training, and multipurpose models. The report also gives a sense of the range of issues that were discussed, including ways to improve future software evaluation."

54:30803 United Nations. Department of International Economic and Social Affairs (New York, New York). MortPak--the United Nations software package for mortality measurement. Batch-oriented software for the mainframe computer. No. ST/ESA/SER.R/78, 1988. vii, 264 pp. New York, New York. In Eng.
"The present volume contains the working manual for MORTPAK, a software package for demographic measurement in developing countries, with special emphasis on mortality measurement. MORTPAK includes 16 applications in the areas of life-table and stable-population construction, graduation of mortality data, indirect mortality estimation, indirect fertility estimation, and other indirect procedures for evaluating age distributions and the completeness of censuses. The package incorporates developed techniques that take advantage of the United Nations model life tables and generalized stable-population equations. The present document is one of two produced by the United Nations providing such software. It contains a batch-oriented interface which is designed for mainframe computer users but which nevertheless is easily installed on a microcomputer."
