The Methods and Materials of Demography


Book Description

Like the original two-volume work, this work attempts to present a systematic and comprehensive exposition, with illustrations, of the methods used by technicians and research workers in dealing with demographic data. The book is concerned with how data on population are gathered, classified, and treated to produce tabulations and various summarizing measures that reveal the significant aspects of the composition and dynamics of populations. It sets forth the sources, limitations, underlying definitions, and bases of classification, as well as the techniques and methods that have been developed for summarizing and analyzing the data.

Demography: Analysis and Synthesis, Four Volume Set


Book Description

This four-volume collection of over 140 original chapters covers virtually everything of interest to demographers, sociologists, and others. Over 100 authors present population subjects in ways that provoke thinking and lead to the creation of new perspectives, not just facts and equations to be memorized. The articles follow a theory-methods-applications approach and so offer a kind of "one-stop shop" that is well suited for students and professors who need non-technical summaries, such as political scientists, public affairs specialists, and others. Unlike shorter handbooks, Demography: Analysis and Synthesis offers a long overdue, thorough treatment of the field. Choosing the analytical method that fits the data and the situation requires insights that the authors and editors of Demography: Analysis and Synthesis have explored and developed. This extended examination of demographic tools not only seeks to explain the analytical tools themselves, but also the relationships between general population dynamics and their natural, economic, social, political, and cultural environments. Limiting themselves to human populations only, the authors and editors cover subjects that range from the core building blocks of population change--fertility, mortality, and migration--to the consequences of demographic changes in the biological and health fields, population theories and doctrines, observation systems, and the teaching of demography. The international perspectives brought to these subjects is vital for those who want an unbiased, rounded overview of these complex, multifaceted subjects. Topics to be covered: * Population Dynamics and the Relationship Between Population Growth and Structure * The Determinants of Fertility * The Determinants of Mortality * The Determinants of Migration * Historical and Geographical Determinants of Population * The Effects of Population on Health, Economics, Culture, and the Environment * Population Policies * Data Collection Methods and Teaching about Population Studies * All chapters share a common format * Each chapter features several cross-references to other chapters * Tables, charts, and other non-text features are widespread * Each chapter contains at least 30 bibliographic citations

Report on Intrauterine Contraceptive Devices


Book Description

Intrauterine devices (IUDs) have an antifertility effect in every animal tested, but this effect is manifested differently among the species. 6-8 million women use the IUD with a pregnancy rate in the United States of from 1.5-3/100 women during the first year of use. These rates decline with use. 80% will continue with the device in the first year, 70% for the second, and about 50% by the fifth year. Adverse reactions include irregular bleeding and cramps for the first 2-3 months and this accounts for 60% of removal. Pelvic inflammatory disease has been reported to be about 2.5% the first year, 1.5% during the second. Highest incidence was in the first month after insertion. The Committee recommended more stringent standards for inserters and devices and more care in insertion. A survey of the Fellows of the American College of Obstetricians and Gynecologists disclosed 15 instances of intestinal obstruction following perforation of the uterus, 13 in which the closed type IUD was used. "The Committee is adverse to the use of currently available closed devices, except in very unusual circumstances." Monitoring women wearing IUDs for cancer in the same manner as for normal women was suggested. The mortality figure for IUDs was .2/10,000 insertions. The current legislation under consideration by the Food and Drug Administration for certain classes of devices secured or placed in the body was considered satisfactory, with means for confidential reporting of adverse reactions recommended. The Committee recommended areas for further research. Task force reports and a bibliography of clinical reports on IUDs in the English literature 1959-1967 were presented. The report includes a list of available IUDs and exhibits of labeling submitted by some manufacturers.
