    Assessing the United Nations urbanization projections for the Asian Pacific.

    Ledent J; Rogers A

    In: Population structures and models: developments in spatial demography, edited by Robert Woods and Philip Rees. Boston, Massachusetts/London, England, George Allen and Unwin, 1986. 367-89.

    The fundamental question addressed in this chapter is the reasonableness of available projections of urbanization, such as those recently published by the United Nations....Drawing on simple models of urban and rural population dynamics, we propose two alternative methods for assessing projected urbanization paths in terms of their underlying assumptions. One focuses on the implied rural-urban migration flows, whereas the other emphasizes the association between urbanization and economic development. The case of the Asian Pacific region is given as an example. (EXCERPT)

    Population projections: methodology of the United Nations.

    United Nations. Department of International Economic and Social Affairs

    New York, N.Y., United Nations, 1984. 85 p. (Population Studies, No. 83; ST/ESA/SER.A/83)

    Upon a recommendation of the Population Commission, at its 20th session in January 1979, the Secretary General of the United Nations convened an Ad Hoc Group of Experts on Demographic Projections from 16 to 19 November 1981 at the UN Headquarters to discuss the methodology used for demographic projections and to consider the relationship of demographic projections to development change and population policies. The expert Group was also requested to provide guidelines and make recommendations to the Secretary-General on how to incorporate demographic changes into the methodology to be used for the next round of world population projections to be prepared by the UN Population Division in collaboration with the regional commissions. The papers prepared by members of the Expert Group as well as those prepared by the Population Division are reproduced in this publication. The recommendations of the Expert Group and a summary of the papers and discussion are also included. The topics addressed in this publication are: 1) problems in making population projections; 2) integration of socioeconomic factors in population projections; 3) population projections as an aid to the formulation and implementation of population policies; 4) current projection assumptions for the United Nations demographic projections; 5) expectations and progressive analysis in fertility prediction; 6) use of the intermediate factors in fertility projections; 7) family planning and population projections; 8) progress of work on a fertility simulation model for population projections at the UN Secretariat; 9) mortality trends and prospects in developing countries: some "best data" indications; 10) the urban and city population projections of the UN: data, definitions and methods; 11) a critical assessment of urban-rural projections with special reference to UN methods; and 12) projections in Europe: some problems.
