This article deals with the problems of modeling the population densities of cities. Two types of models, the quadratic gamma and the equilibrium, are discussed and compared. (Author/MK)

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…

Argues that the loss-function analysis used to adjust the census of 1990 depends on estimating probable errors in census and adjustment and that data from field-validation projects does not provide estimates accurate enough for the purpose. The loss-function analysis is actually driven by assumptions, not data. (SLD)

One of a special series on population change and development, this paper focuses primarily on the programs and policies responsible for mortality or fertility change, rather than on the growth impact of a mortality or fertility change per se. The first portion of the document examines three models for assessing the population growth implications…

This unit, which looks at applications of linear algebra to population studies, is designed to help pupils: (1) understand an application of matrix algebra to the study of populations; (2) see how knowledge of eigen values and eigen vectors is useful in studying powers of matrices; and (3) be briefly exposed to some difficult but interesting…

Several simulations of population, income, and employment in rural and urban America during 1970-2000 were made based on alternative assumptions. The assumptions entailed implementation of certain policies that might effect a more equal rural-urban balance by the year 2000, in addition to a continuation of current trends. If basic trends continue,…

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…

A variety of ecological, economic, and social changes are now reshaping rural America. The deterioration of the economic structures and perceived quality of social life in large metropolitan centers of the United States has stimulated the dispersal of population and economic resources throughout rural America. During the last decade almost three…
