    United Nations. Ad Hoc Expert Group on Demographic Projections

    In: United Nations. Department of International Economic and Social Affairs. Population projections: methodology of the United Nations. Papers of the United Nations Ad Hoc Expert Group on Demographic Projections, United Nations Headquarters, 16-19 November 1981. New York, United Nations, 1984. 4-6. (Population Studies No. 83 ST/ESA/SER.A/83)

    These recommendations refer specifically to the work of the Population Division of the UN and the regional commissions and more generally to the work of the specialized agenices, which prepare projections of labor force and school enroolment. The current recommendations may be regarded as updating an earlier detailed set that was issued by a similar group of experts who convened in New York in November 1977. The recommendations cover general considerations, sources and assumptions, evaluation of projections and their uses, and internal migration and urbanization. The Population Division should consider the question of an optimal time schedule for publishing new estimates and projections in order to avoid unduly long intervals between publications and intervals so short as to cause confusion. The UN Secretariat has an important role in pursuing work on methodology of projections and making it available to demographers in the developing countries. Unique problems of demographic projection exist for those countries with particularly small populations. It is proposed that the Population Division prepare special tabulations, whenever possible, giving the estimated age and sex distribution for these countries. Future publications of population projections prepared by the Population Division should indicate the major data sources on which the projections are based and note if the data were adjusted before inclusion. In addition, some grading of the quality of the base data should be presented. For the UN set of national and international population projections, a more comprehensive system of establishing assumptions about the future trends of fertility is needed. The Secretariat needs to focus more attention on the evaluation of its population projections. UN publications of projections should report on the main errors in recent past projections with respect to estimates of baseline levels and trends and provide some evaluation of the quality of the current estimates. It is recommended that the UN encourage countries to establish a standard definition of urban which would be used for international comparisons but generally not replace current national definitions. The Secretariat should review the techniques currently used to project urban-rural and city populations and search for methodologies appropriate to the level of urbanization and the quality of data which would improve the accuracy of the projections. The Division should regularly produce long range population projections for the world and major countries and should continue and expand its household estimates and projection series, which provides information essential to government administrators and planning agencies, businesses, and researchers in all countries.

    [Recommendations of the Population World Plan of Action and of the United Nations Expert Group on Population Distribution, Migration and Development] Recomendaciones del Plan de Accion Mundial sobre Poblacion y del Grupo de Expertos de la Organizacion de las Naciones Unidas sobre Distribucion de la Poblacion, Migracion y Desarrollo.

    De Oliveira O

    In: Reunion Nacional sobre Distribucion de la Poblacion, Migracion y Desarrollo, Guadalajara, Jalisco, 11 de mayo de 1984, [compiled by] Mexico. Consejo Nacional de Poblacion [CONAPO]. Mexico City, Mexico, CONAPO, 1984. 21-31.

    Highlights are presented of the expert meeting on population distribution, migration, and development held in Hammamet, Tunisia, in March 1983 to prepare for the 1984 World Population Conference. Rafael Salas, Secretary General of the World Population Conference, indicated in the inaugural address of the meeting that changes in the past 10 years including the increasing importance of short-term movements, illegal migrations, and refugees would require international agreements for their resolution. In the area of internal migrations, Salas suggested that in addition to migration to metropolitan areas which continues to predominate, short-term movements of various kinds need to be considered in policy. Improvement in the quality of life of the urban poor is an urgent need. Leon Tabah, Adjunct Secretary General of the World Population Conference, pointed out that population distribution and migration had received insufficient attention in the 1975 World Population Conference, and that the World Population Plan of Action should be modified accordingly. Among the most important findings of the meeting were: 1) The Plan of Action overstressed the negative effects of urbanization and rural migration. Available evidence suggests that migration and urbanization are effects rather than causes of a larger process of unequal regional and sectorial development 2) The historical context of each country should be considered in research and planning regarding population movements. 3) Analyses of the determinants and consequences of migration were reexamined in light of their relationship to the processes of employment, capital accumulation, land tenure, technological change, ethnic and educational aspects, and family dynamics. 4) The need to consider interrelationships between urban rural areas in formulation of policy affecting population distribution was emphasized. 5) National development strategies and macroeconomic and sectoral policies usually have stronger spatial effects than measures specifically designed to influence population distribution, and should be examined to ensure compatability of goals. 6) Population distribution policies should not be viewed as ends in themselves but as measures to achieve larger goals such as reducing socioeconomic inequalities. 7) Multiple levels of analysis should be utilized for understanding the causes and consequences of population movements. 8) Programs of assistance should be organized for migrants and their families. 9) The human and labor rights of migrants and nonmigrants should be considered in policy formulation. 10) Policies designed to improve living and working conditions of women are urgently needed.

    Population growth and the cities of Asia.

    Laquian AA

    POPULI. 1986; 13(1):15-25.

    Over half of the 75 world cities projected to have populations exceeding 4 million by the year 2000 are in Asia. Asia's planners and city officials have developed and tested numerous policies and istruments for coping with rapid urban growth. These efforts have benefited from increased understanding of the demographic causes of urbanization, especially rural-urban migration. On an aggregate plane, the main consequences of urbanization have been metropolitanization, primacy, polarization, and centralization. Economic wealth, political power, and social status have become concentrated in capital cities; within cities, the increasing gap between privileged elites and impoverished masses has contributed to political radicalization among the poor. To cope with the problems of urbanization, many Asian authorities have set up metropolitan governments to handle area wide functions. Some cities have redefined their jurisdictions to incorporate outlying rural territories and small towns. The expansion of metropolitan jurisdiction prevents local government fragmentation and duplication of public services. It also allows for land-use controls over undeveloped areas that will be needed for urban expansion. In recent years, natural increase has been a more important factor in rapid urban growth than migration; thus, many Asian countries have adopted family planning programs to curb population growth. Most of the factors associated with declining fertility--educational achievement, employment of women, access to family planning services--are closely associated with urban culture, and urban fertility rates tend to be lower than those in rural areas. To be valid, urban policy goals must be integrated into broader development goals. Population issues permeate all stages of the planning process and should be viewed both as a cause and a consequence of economic and social development.

    The state of world population 1986.

    Salas RM

    POPULI. 1986; 13(1):5-14.

    Within the next 50 years, the predominantly rural character of developing countries will shift as a result of rapid world urbanization. In 1970 the total urban population of the more developed world regions was almost 30 million more than in the less developed regions; however, by the year 2000 the urban population of developing countries will be close to double that in developed countries. A growing proportion of the urban population will be concentrated in the biggest cities. At the same time, the rural population in developing countries is expected to increase as well, making it difficult to reduce the flow of migrants to urban centers. Although urban fertility in developing countries tends to be lower than rural fertility, it is still at least twice as high as in developed countries. The benefits of urbanization tend to be distributed unevenly on the basis of social class, resulting in a pattern of skewed income and standard of living. Social conditions in squatter settlments and urban slums are a threat to physical and mental health, and the educational system has not been able to keep up with the growth of the school-aged population in urban areas. The problems posed by urbanization should be viewed as challenges to social structures and scientific technologies to adapt with concern for human values. It is suggested than 4 premises about the urbanization process should guide urban planners: 1) urban life is essential to the social nature of the modern world; 2) urban and rural populations should not be conceptualized in terms of diametrically opposed interest groups; 3) national policies will have an impact on urban areas, just as developments in the cities will impact on national development; and 4) the great cities of the world interact with each other, exchanging both trade and populations. The United Nations Family Planning Association stresses the need for 3 fundamental objectives: economic efficiency, social equity, and population balance.

    Supercities: problems of urban growth.

    Leepson M

    Editorial Research Reports. 1985; 2(20):887-904.

    The author discusses aspects of urbanization, living conditions in urban centers, and selected policies, summarizing findings from recently published sources. U.N. population projections for selected urban areas for the year 2000 are compared with 1950 estimates, and the proportions of the population living in urban areas in various regions of the world are contrasted. Attention is given to living conditions in rapidly growing and crowded cities, including Mexico City, Mexico; Sao Paulo and Rio de Janeiro, Brazil; Lagos, Nigeria; and Cairo, Egypt. Statements on urban growth issued by the U.N. Fund for Population Activities are considered.

    The miracle of a mountain moving out to the sea: the creation of new human space.

    Kuroda T

    Joicfp Review. 1985 Oct; 10:39-40.

    Port Island is an artificial island made up of sand and soil from Mount Takakura in the Rokko mountain range of Japan. The materials were carried to the coast of Suma a distance of 7.1 kilometers by a specially devised overhead conveyor belt from Kobe City. Work on the island still continues today. On the average, 7000 dump trucks a day have been mobilized at the conveyor belt facilities. The materials are transported from the coast by pusher-barges that have specially designed bottoms that open and dump the building materials on the sea bed. The island is linked to Kobe City by a huge bridge. It is serviced by a fully automatic monorail. A new city was also created at the site where the sand and soil were removed. A joint study with the Kobe City authority and local experts under the support and cooperation of the United Nations Fund for Population Activities (UNFPA) was initiated. The administrative structure and financing required of a project of this magnitude need to be examined. The organizational structure and management style of local governments undertaking the project were non-bureaucratic, efficient and flexible. Kobe City authorities secured the necessary funds by issuing the German mark bond. A research on Kobe City and the redistribution of population is planned. More living space and better living conditions resulted from the project.

    Some problems in the making of population projections.

    Tabah L

    In: United Nations. Department of International Economic and Social Affairs. Population projections: methodology of the United Nations. Papers of the United Nations Ad Hoc Expert Group on Demographic Projections, United Nations Headquarters, 16-19 November 1981. New York, United Nations, 1984. 15-6. (Population Studies No. 83; ST/ESA/SER.A/83)

    As the UN demographic estimates and projections cover all the developed and developing countries, special problems are encountered in data collection and evaluations. The responsibility for the UN projections rests primarily with the Population Division, but the results are the product of collaboration by all responsible offices within the UN system. This is 1 of the strengths of the UN population projections, yet there are numerous problems concerning those projections. Aside from the perpetual difficulties with collection and estimation of basic demographic indicators from incomplete data, all of which must be continuously undertaken, there are 8 major problems which have become more important in recent years and concern the current UN demographic projections. The 1st problem is the question of meeting the needs of the users who are the researchers, the planners, and the policymakers. The 2nd problem is that significant improvement can be made in the methodologies with, on the 1 hand, the prodigious advances in calculation devices and research techniques and on the other, a better knowledge of the economic and social context of demographic variables. The 3rd major problem in the component method of projections of fertility, which continues to be the most influential component to the future population of most nations. Another component of projection, mortality, has become a pressing issue in the field of projection as well. Knowledge of mortality in the third world is highly fragmentary. The 5th problematic issue is urbanization and city growth. There are severe problems with data comparability and projection methods. Sixth, for several developing and developed countries international migration plays a significant role in their population growth. More problematic than estimating the current net numbers of migrants is formulating assumptions about future patterns of international migration. Seventh, thus far demographic projections have largely been based on the demographic theory of transition, which appears to continue to be useful for developing countries. Yet, the demographic transition models are affected by a wider variety of trajectories than anticipated. Finally, no one has been able to explain clearly the major simultaneous movements of fertility of the developed countries. The question of obvious policy significance is what will happen in the future.

    Reproductive science and contraceptive development: recommendations to international assistance agencies.


    In: Rockefeller Foundation. Bellagio 4 population conference. A conference sponsored by The Rockefeller Foundation, Ulvshale, Denmark, June 7-9, 1977. New York, Rockefeller Foundation, November 1977. p. 63-77

    Focus is on the findings of a 2-year study of reproduction science and contraceptive development that are of particular relevance to the work of international asssitance agencies. The first 3 of 20 recommendations made in the Report's Summary of Findings and Recommendations are especially important. The recommendations are: 1) a variety of safe and effective methods of fertility regulation beyond those now available is urgently needed, and there must be increased efforts ranging from fundamental research on the reproductive processes to targeted activities in contraceptive development; 2) more attention must be given to studies of intermediate and long-term safety of methods yet to be developed; and 3) by 1980, allocations for research in the reproductive sciences related to contraceptive development and evaluation by governmental agencies should comprise substantially higher proportions of total expenditures for medical research and development assistance than is now the case. Worldwide expenditures for the reproductive sciences and contraceptive development reached a peak in 1974 and have since decreased in 1975 and 1976. Clearly, the amount of relevant research being supported throughout the world has declined at a time when the promise of major new developments is extremely high and when bringing new products to market calls for large expenditures of funds to assure their efficacy and safety. Additional focus is given to institutional and human resources, contraceptive development in the public sector, regulation and ethics of human experimentation, the special conference on contraceptive development in the public sector that was held April 27-29, 1977, rationale for support of reproductive science and contraceptive research, institutional arrangements for research in reproduction and contraceptive development, financial requirements, and new funding mechanisms.
