A discussion of the Demographic Transition is included in many Environmental Biology or Environmental Science classes. The Demographic Transition occurs as a nation becomes more urban and wealthy, and was widely observed in the twentieth century. The phenomenon includes decreasing family size (fewer children) across generations. In this classroom…

This report describes and develops a model for coordinating a variety of demographic and social statistics within a single framework. The framework proposed, together with its associated methods of analysis, serves both general and specific functions. The general aim of these functions is to give numerical definition to the pattern of society and…

Comments by two reviewers (Garrett Hardin and Stephen Berry) on the book The Limits to Growth'' by Meadows and others. The nature of the models used, and the reactions of book reviewers are discussed. (AL)

There has long been a need for a systematic set of instructions for the projection of populations for such subnational areas as states, provinces, districts, or statistical planning areas; and for specific groups of population which may overlap different areas within a country, such as the labor force, various occupation groups, the school age…

THIS NOTE DESCRIBES AND CRITICIZES THE VARIOUS METHODS CURRENTLY IN USE FOR PROJECTING BIRTHS--(1) COHORT-FERTILITY, (2) AGE-SPECIFIC, (3) COHORT-FERTILITY (SCRIPPS), AND (4) MARRIAGE-PARITY-PROGRESSION. VARIABLES USED IN THE VARIOUS METHODS ARE AGE OF MOTHER, COMPLETED FERTILITY, MARRIAGE STATUS, TIME SINCE MARRIAGE, PARITY, AND BIRTH INTERVAL.…

A management model uses a population perspective that examines types of change occurring in the environment of populations of organizations and results in four kinds of decline (erosion, contraction, dissolution, and collapse). It is used to explain several population-related organizational phenomena. (MSE)

Reports a test of the stability of the model used in Jay Forrester's World Dynamics''. When Forrester's fundamentally Malthusian assumptions were replaced by technological-optimist views, computer simulations predicted a stable population with increasing quality of life, rather than a population crash and decreasing quality of life. (AL)

A population ecology model of institutional fitness broadens the scope of perspectives on organizational success. The approach allows systematic thinking about internal and external factors identifies the critical dependency relationships between a college and other organizations that supply resources. (MLW)

Explains and illustrates three different kinds of models: systems, process (linear), and a systems-process combination. Gives examples of models from ecology, communications, economics, demography, and education to demonstrate the use of models in policy decisions. (DC)

The aging of the population is one of the major influences on the environment in which vocational education operates. The number of people 65 and older will increase more slowly in next 25 years than in the past. Improvements in working conditions, health care, and pension plans since World War II have made those who will be 65 by the end of the…

An empirical approach to the development of a system of social indicators was suggested in this paper. The paper also suggested research developed around a more inductive approach to social indicator research with 3 methodological phases representing increasing levels of methodological sophistication. The first steps attempted to conceptualize…

Changes in the composition of colleges and universities during the 1970s and the changes in the subpopulation of institutions with a high commitment to liberal arts education were studied. The effect these changes had on the diversity of the population and subpopulation is described. (MLW)

Describes Albuquerque (New Mexico) Public Schools' development of a model to forecast enrollment growth. Recommendations include studying local demographics, seeking clues to future development, examining the age of neighborhoods, adding up rental property, and developing strong professional relationships with city planners, real estate…

Data for 318 metropolitan areas confirm the Burgess model's positive relationship between social status and residential distance from the urban core. Over time, all categories of metropolitan areas moved in the predicted direction of status distribution, with stronger associations for older, larger, and more industrial cities. Contains 53…

A group of experts on population and development planning met in Bangkok, Thailand in July, 1977. The meeting was organized by the United Nations Economic and Social Commission for Asia and the Pacific. This report is the result of background papers used at the conference, reactions to the papers, and further writing. The purpose of the meeting…
