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.

55:40762 Garcia-Bogue Research and Development (Chicago, Illinois). POPSYN: synthesizer of population methodology software [MRDF]. [1989?]. Chicago, Illinois. In Eng.
This is a software system called POPSYN, which combines 90 demography programs into an integrated system. The programs cover topics including general statistical procedures, errors in evaluating demographic data, demographic data adjustment, mortality measurement and life table construction, direct and indirect fertility measurement, nuptiality and migration, population projections, and population models. Specifications for POPSYN include IBM PC/XT/AT/PS2 or compatibles, DOS 3.1 or higher, hard disk with 640k RAM, math co-processor (optional), and Lotus 1-2-3 (version 2.01 or later) for running programmed spreadsheet routines.

55:40763 Lidegaard, Ojvind. Oral contraception in Denmark in 1983 [MRDF]. Pub. Order No. DDA-0797. [1986?]. Danish National Hospital, Neurological Ward: Copenhagen, Denmark. Distributed by Odense University, Danish Data Archives. In Dan. with sum. in Eng.
This file contains 788 cases and approximately 145 variables per case. "788 women between 15 and 45 and representative of the Danish population were asked whether they used or had used oral contraceptives and about their opinions of a possible increased risk of thrombo-embolism among users. 24%, predominantly young women, were users; 37% were previous users while 39% had never used oral contraceptives. The use of oral contraceptives is more common among single women than among married/cohabiting women....About 50% were of the opinion that the use of oral contraceptives increases the risk of thrombo-embolism. Education, occupation or social level had no influence on the frequency of the use of oral contraceptives."

55:40764 Matthiessen, Christian W. Urban growth in Denmark: distance matrix [MRDF]. Pub. Order No. DDA-0701. [1986?]. University of Copenhagen, Institute of Geography: Copenhagen, Denmark. Distributed by Odense University, Danish Data Archives. In Dan. with sum. in Eng.
This file contains 75,625 cases, 12 variables per case, and a data matrix of 275 by 275 fields; the data are in character format. Census and survey data are provided for the years 1970-1982 for all municipalities in Denmark with more than 200 inhabitants. "Urban growth in Denmark is assessed in relation to potential population sizes and potential occupational structure. These variables have been calculated by means of a kind of 'gravity simulation' which includes distance. This 'gravity simulation' is determined by means of the parameters of the distance matrix: physical distance, migration and commuting."

55:40765 United Nations. Department of International Economic and Social Affairs. Population Division (New York, New York). ABACUS [MRDF]. 1989. New York, New York. In Eng.
"This is a computer program for population projection used by the United Nations Population Division. The program uses the cohort-component method to project population classified by sex and five-year age groups at five year intervals for up to 100 years in each run. The program provides many options, including backward projection, annual interpolation, nine families of model life tables, integration of observed and model life tables, three families of model fertility schedules, and a parametric system of model migration schedule, so that users could choose from many different formats and procedures of formulating their assumptions. Three versions are available for IBM computers and compatibles: for microcomputers with coprocessors, for microcomputers without coprocessors, and for mainframe computers. [An] accompanying manual is provided [Document No. ST/ESA/SER.R/92]."

55:40766 United Nations. Department of International Economic and Social Affairs. Population Division (New York, New York). Demographic indicators, 1988 [MRDF]. 1989. New York, New York. In Eng.
"This is a diskette containing United Nations demographic estimates and medium variant projections of 13 selected demographic indicators for all countries (with population size of 300,000 or more around 1985), regions, and major areas of the world. Data are presented quinquennially for the years 1950-2025. The selected indicators include the population size, growth rate, crude birth rate, crude death rate, total fertility rate, expectation of life at birth, and infant mortality rate. The data contained on this diskette are a subset of those found on the United Nations magnetic tape, World Population Prospects, 1988...and fully described in World Population Prospects, 1988, published by the United Nations in 1989. Accompanying technical documentation is provided."

55:40767 United Nations. Department of International Economic and Social Affairs. Population Division (New York, New York). Sex and age, 1988 [MRDF]. 1989. New York, New York. In Eng.
"This is a set of three diskettes containing United Nations estimates and medium variant projections of population classified by sex and age for all countries (with population size of 300,000 or more around 1985), regions and major areas of the world. Data are presented, quinquennially, for the years 1950-2025. The population figures contained on these diskettes are a subset of those found on the United Nations magnetic tape, World Population Prospects, 1988...and fully described in a forthcoming United Nations publication, Global Estimates and Projections of Population by Sex and Age, 1988. Accompanying technical documentation is provided."
