In: Population perspectives. Statements by world leaders. Second edition, [compiled by] United Nations Fund for Population Activities [UNFPA]. New York, New York, UNFPA, 1985. 105.Mauritania's Military Committee of National Salvation, inspired both by religious teachings and its participation in the 1974 World Population Conference, has adopted a social and economic development plan aimed at improving the quality of life of the population. With the financial and technical assistance of the United Nations, Mauritania has carried out its 1st national population census and fertility survey; in addition, a Center for Demographic and Social Research was established in 1983. Health efforts are currently aimed at reducing infant and child mortality. Mauritania's approach to population control primarily stresses improvements in maternal and child health. In education, efforts have been directed toward increasing school attendance rates and improving the quality of teaching. Unemployment and underemployment are also being given serious attention. To stem migration from rural to urban areas, which accelerated during the drought, sectoral projects seek to keep people in their areas. The creation of mass education structures is the most tangible expression of the Government's commitment to involving Mauritanians in shaping their own political, cultural, economic, and social destiny. For true harmonization of national population policies, however, a more just, humane international economic order is needed.
Voorburg, Netherlands, Netherlands Interuniversity Demographic Institute, 1985 Sep. ix, 56 p. (Working Paper of the N.I.D.I. No. 63)The objective of this report is to introduce the available techniques of life history analysis to study the data collected by the national migration surveys and to demonstrate the relevance of such techniques to provide more insight into to the problems addressed by the ESCAP migration and urbanization project. The 2nd section of the report introduces the basic concepts, with special reference to migration, and contains a simple example. Section 3 deals with 3 further issues which may arise while modeling migration histories: the alternative definitions of the state-space; the definition of the time dependence; and heterogeneity considerations and ways of dealing with heterogeneity for discrete state stochastic models of migration. The 4th section focuses on some major problems which may arise while estimating stochastic models of migration histories with ESCAP migration his. 2 issues are emphasized in this section: problems with the measurement of the timing of the events and issues related to using the information on the covariates of migration. Continous time stochastic models provide a powerful means of modeling event sequences. Migration histories consist of information on the times and the characteristics of migration experienced by individuals. More conventional ways of modeling such data are the dummy variables regression, the logit regression, or aggregation of the data are to form contingency tables and application of the log-linear models. Continous time event history models easily be generalized to incorporate complex designs of the state space, which express the moves between residences, and to provide detailed and cross nationally comparable information on the patterns of time dependence. Additionally, they are based on the estimation techniques which do not require unrealistic assumptions. These models aim at identifying a dynamic process that underlies the observed data. Estimated parameters of these models provide a description of the time dependence and also provide quantitative information about the effects of exogenous variables on the phenomenon of interest. The dependent variable of the continous time event history models is usually the instantaneous transition rate which is not directly observable. The estimated coefficients of the exogenous variables may be interpreted the same as the coefficients of a regression model, except that they usually have a multiplicative relation with the dependent variable. Once models of fundamental parameters of the underlying process are designed and estimated, many implications of such a process may be derived.

Brussels, Belgium, Centrum voor Bevolkings- en Gezinsstudien [CBGS], 1985. viii, 274 p. (CBGS Monografie No. 1985/3)The aim of this report is to summarize the results of the International Conference on Population, held in Mexico City in August 1984, and to review the findings of working groups and regional meetings held in preparation for the conference. Chapters are included on developments in the decade since the 1974 World Population Conference, world population trends, fertility and the family, population distribution and migration, mortality and morbidity, population and the environment, results of five regional U.N. conferences, the proceedings and results of the Mexico City conference, and activities involving Belgium.
