    A perspective on long-term population growth.

    Demeny PG

    Population and Development Review. 1984 Mar; 10(1):103-26.

    This paper presents some of the results of projections prepared by the World Bank in 1983 for all the world's countries. The projections (presented against a background of recent demographic trends as estimated by the United Nations) trace the approach of each individual country to a stationary state. Implications of the underlying fertility and mortality assumptions are shown mainly in terms of time trends of total population to the year 2100, annual rates of growth, and absolute annual increments. These indices are shown for the largest individual countries, for world regions, and for country groupings according to economic criteria. The detailed predictive performance of such projections is likely to be poor but the projections indicate orders of magnitude characterizing certain aggregate demographic phenomena whose occurrence is highly probable and set clearly interpretable reference points useful in discussing contemporary issues of policy.

    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.
