"The purposes of this paper are to analyze the Argentine legislation between 1870 and 1989 that has directly or indirectly affected the dynamics and structure of population, as well as to reveal the ideology of population policies supported by hegemonic social forces. This analysis takes into consideration the different development strategies that have been implemented. Our study explores the way in which the different governments have approached the issue of population, and, more specifically, it analyzes the relation between public policies, population policies, development strategies, and political processes represented in State laws."

"The paper presents the Latin American demographic situation and trends since 1950, with special emphasis on differential mortality across and within countries.... The large declines in mortality, specially those at young ages, are linked to changes in epidemiological profiles which imply a greater relative importance of non-transmissible diseases and a lesser role of infectious and parasitic diseases. Population ageing also contributes to these changes due to the increased fraction of adult and elderly population. In the majority of countries, excessive mortality due to avoidable causes is still present among the poor." (SUMMARY IN ENG), (excerpt)

"This paper reports some results of analyzing migratory dynamics in the Metropolitan Area of Mexico City, which ever since the 1970-1980 decade have affected other regions of the country, mainly the State of Mexico. The analysis describes different types and modes of migratory movement: metropolitan (from Mexico City), inter-county (within each state), and interstate (between Mexico City and other states). Data was provided by the XI Population and Household Census of 1990." (SUMMARY IN ENG), (excerpt)

"The objective of this paper is to discuss the role that three of the proximate determinants of fertility (marriage, contraception and post-partum insusceptibility) have played in fertility change in Latin America and the Caribbean. First we look at issues of data availability and comparability on measures of the proximate determinants from retrospective surveys. Most of the data utilized come from the World Fertility Survey (WFS) and the Demographic and Health Surveys (DHS) projects. Second, we present results from the most widely applied model for assessing the impact that these proximate determinants have on fertility, that of Bongaarts....Finally, we compare the results from the application of the Bongaarts model with those from an alternative method proposed by Moreno. Both models show that increased use of contraception is by far the most important reason for fertility decline, with marriage and post-partum insusceptibility making much smaller contributions. However, the second model suggests that the role of the marriage and post-partum insusceptibility factors is much smaller than is shown by the Bongaarts model." (SUMMARY IN ENG), (excerpt)

Both high rates of labor force growth and large dependency ratios are forecast in this paper for the countries of Latin America in the 1990s. The author concludes that "population and employment problems must be given high priority in bilateral negotiations and/or with international organizations when deciding upon structural adjustment strategies."

"In this paper, the author analyzes the evolution of migration to Mexico City based on information generated by the National Survey on Migration to Urban Areas.... The findings support the hypothesis that there has been a decrease in the intensity of in-migration towards capital. The rural origin of the migrants prevails; the majority of these are young people coming from the states closest to the city, with low levels of schooling. An increase is observed in out-migration from Mexico City to other major cities in the country...." (SUMMARY IN ENG), (excerpt)

Changes in the relationship between population factors and the development process in Mexico from 1940 to the present are reviewed. The authors show how the development that occurred up to about 1970 both absorbed and encouraged rapid population growth. They then describe how the emergence of problems concerning this relationship led to the development of a population policy during the 1970s. "The paper then takes up the implementation of that policy and the determinants of the fertility decline that took place afterwards, and closes with a brief review of the implications that demographic considerations have for Mexico's future."

"This paper examines characteristics of recent rural-urban out-migrants leaving households in the Sierra of Ecuador. A large, household survey focussing specifically on migration is utilized, allowing detailed crosstabulations by sex and origin-destination combination and providing information about migrants generally not found in more generic surveys or censuses. Differences are noted between migrants and non-migrants in basic demographic characteristics, reasons for migrating, and economic activities prior to and subsequent to moving. Differences in the characteristics of migrants moving between various types of place of origin and place of destination are also noted." (SUMMARY IN ENG), (excerpt)

"The paper analyzes some problems related to the census measurement of internal migration according to the three following aspects: The lack of agreement between the proposed objectives and the type of question made; questionnaire design errors and enumeration errors; and inadequate data elaboration." The geographic focus is on Latin America. Problems concerning data on place of birth or place of previous residence and how these can affect the calculation of migration trends are considered.

"The paper analyzes the demographic aspects of the aging of the population in Latin America. Aging is still incipient in the great majority of countries of the region, but it will become generalized and will be accentuated especially after the year 2000. The dependency relationship will continue to decrease until higher levels of aging are reached; the proportion of the aged in the potentially dependent population will increase and the relationship between the population from 15 to 59 years of age and over 60 will decrease. "At present, the proportion of single women [over 60] is much higher than that of single men. From the information on participation in the labour force and the access that the aged have to income or pension benefits, the paper also shows that most of the aged that continue to work do so because they require an income for subsistence. "The paper finally includes some conclusions on the causes and consequences of the aging of the population and the actions that would be necessary to broaden knowledge for the formulation of policies."
