Crews of 18 U.S. Navy combat vessels rated their living and working conditions aboard ship, including degree of crowding. Three different types of measures corresponding to different definitions of crowding were constructed. These separate crowding measures correlated uniquely with satisfaction and illness criteria.

Evidence of high population density's serious inhibiting effects on the reproductive, aggressive, withdrawal and sexual behavior of various animals, motivated a study of human pathology in overcrowded areas. Ecological relationships in Chicago and their impact on human behavior were assessed. The number of persons per acre, Standardized Mortality…

The author suggests that numbers and distribution of people should be given highest priority in dealing with environmental quality. If population problems are solved, then other environmental problems will be prevented or solved. New Mexico, contends the author, must determine the balance between growth and quality of life. (MR)

Author attempts to suggest population education materials most appropriate to the Catholic educational system. (GB)

Two perspectives on carrying capacity and population growth are examined. The first perspective, "Carrying Capacity and Rapid Population Growth: Definition, Cases, and Consequences" (Robert Muscat), explores the possible meanings of the idea of carrying capacity under developing country conditions, looks at historical and present-day cases of…

Three-part report pinpointing problems and uncovering solutions for the dual concepts of density (ratio of people to space) and crowding (psychological response to density). Section one, A Primer on Crowding,'' reviews new psychological and social findings; section two, Density in the Suburbs,'' shows conflict between status quo and increased…

This paper provides a descriptive overview of research on the consequences of overcrowding and the development of high population densities in animals, and speculates on the relevance of these studies for similar human phenomena. Three major foci are distinguished: (1) the effect of high population densities on animal behavior; (2) the nature of…

Discusses energy and environmental problems encountered by mankind in the attainment of the goal of an ideal world. Indicates that man will in any event be happier than now after the gradual implementation of negative population growth. (CC)

The relationship between changes in the timing and quantity of fertility, such as those that might result from an effective family planning program in developing countries, and changes in child and maternal mortality is examined. Results from five multivariate studies estimate the changes in mortality that might occur from altering maternal age,…

Future trends in population are described as they relate to developed and developing nations. It is suggested that for the next 20 years there will be a decrease in population growth rates for all areas of the world except Africa. (Author/SA)

Psychology and Population is defined as the study of individual dispositions and behavior that affect the size, structure and dispersion of the population, and the way in which acts of individuals enter into the dynamics of population change. Even this definition was viewed as inadequate, ignoring, as it does, the reciprocal effect of population…

A review of six expert group meetings was organized to discuss various population and development issues and present individual group reports. The review begins with a synthesis of the meetings and gives a brief description of the organizational aspects of the meetings, a summary of recommendations, and an overview of important issues examined at…

A systematic discussion of the consequences of rapid population growth for economics and social systems examines growth resulting from mortality decline in the absence of comparable fertility decline. Growth resulting from net migration is also considered. The background and rationale for the study are supplied in a brief introduction. Part 2…

The determinants of fertility and attempts to extract conclusions that are relevant for fertility reduction policies in developing countries are investigated. The paper suggests that socioeconomic development has a decisive effect in lowering fertility in the long run but in the short run, and for specific households, the effect is not as…
