"This paper uses an economic index to describe the hierarchical structure of the national settlement system and describes the changes among the sixties, eighties and nineties. We found great territorial changes for the first period. The conclusions proposed are that there is a decentralisation at [the] national level, but at the same time, there is a centralisation at [the] regional level." (SUMMARY IN ENG), (excerpt)

"This paper examines the adult-mortality transition in Costa Rica and its determinants. The risk of dying declined by 80% for young adults and by 40% for old adults from 1920 to 1990. The fastest decline took place in the 1950s for young-adult ages and in the late 1980s for old-adult ages.... By 1990, about 40% of Costa Rican deaths are caused by accidents and violence at young-adult ages and by cardiovascular diseases at old ages. Infectious and nutritional-related conditions (especially respiratory tuberculosis and malaria) account for three-fourths of the adult-mortality decline between 1951 and 1971, but only for 30% since that year on."

"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)

"This paper begins by reviewing some conceptual frameworks for the study of female mortality and indicates some of its application problems. Next it presents results of mortality of women in reproductive-age classified by age, causes of death, and socio-demographic traits (marital status, schooling, and occupation) for ten states [in Mexico] differentiated according to level of development and well-being. The data suggests differences according to age, marital status, and schooling. Finally, testing of the mutual independence and partial independence hypotheses indicates that age, marital status, and schooling correlate to the degree of development of each state."

"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)

"This paper reviews survey-based data regarding contraceptive prevalence and methods employed in Latin America and the Caribbean, with an emphasis on changes in the mix of methods over time. The most striking recent trend is the rise in use of female sterilization.... By contrast, use of male sterilization remains negligible in most countries. The oral contraceptive pill is by far the most popular of the temporary methods, though its prevalence has more often declined than increased in recent years. Together female sterilization and the pill make up around [two-thirds] of contraceptive practice in Latin America and the Caribbean." (SUMMARY IN ENG), (excerpt)

"This paper presents the results of exploratory efforts to examine the determinants of the structure of households in urban areas of Mexico, focusing on those of women with young children.... The empirical analysis uses two cross-sectional national surveys of Mexico, the 'Encuesta Nacional Demografica' 1982 and the 'Encuesta Nacional de Fecundidad y Salud' 1987...."

"The purpose of this paper is to assess urban research in Mexico during the 1980s.... The study is divided into three sections: 1) continuing themes; 2) new themes on urban issues; [and] 3) state policies regarding urban issues. The author notes that in the 1980s, research was conducted for the purpose of analyzing urban realities more explicitly.... She also offers a description of studies that attempt to link state policies, the actors involved, and their impact (or lack of it) on urbanization processes, and discusses the regulatory functions carried out by the state."

"The paper examines the relationship between medium and short-term changes in aggregate economic activity, and national morbidity and mortality rates by certain causes. Although overall mortality conditions have continued to improve during the economic crisis of the nineteen-eighties in the three countries studied, mortality by some causes...[has] discontinued [its] decline and [has] even increased [its] rates in some recent years.... The short-term changes in mortality in Costa Rica and Chile are generally lower than in Guatemala, but tend to be more systematic in their inverse relationship with economic fluctuations in the former. Many of the causes studied affect young and older adults, which are groups that have so far received little attention in evaluations of the health effects of economic crises in the region."

A methodological experiment was conducted as part of the Demographic and Health Surveys (DHS) project to determine whether different approaches to measuring the same variables would yield similar results. The experiment consisted of the use of a new questionnaire, incorporating variants of many of the traditional approaches to the collection of demographic and health data. The experimental questionnaire was applied in 2 countries, Peru and the Dominican Republic at the same time as the standard survey. The most salient feature of this new questionnaire pregnancies, contraceptive practice, and postpartum, marriage, employment, and migration information. In this paper, the authors evaluate whether the use of the calendar in the experimental questionnaire improved the quality of the resulting information on contraception in the DHS surveys from the abovementioned countries. Specifically, the author determine whether the monthly calendar led to better estimates of contraceptive prevalence, failure, and discontinuation, and discuss the advantages and drawbacks of the calendar over the more standard approach. Results from this evaluation suggest that the major advantages of the calendar over the more standard questionnaire are 3-fold: it allows for more complete reports of use for periods prior to the survey; it allows for a detailed study of contraceptive use patterns; and it obtains information which is more internally consistent with other types of information. On the bases of these findings, the DHS project will include a calendar in the new standard questionnaire to be used in the 2nd round of surveys (DHS II).

"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)

This paper describes and analyzes the main characteristics identified in seasonal Guatemalan workers who migrate every year to coffee plantations in the Sosonusco region in the state of Chiapas. Stress is placed on the disadvantageous working and living conditions of said population in their original areas of residence, as a necessary referent for understanding the nature and function of seasonal migratory work as a part of a social sector whose living conditions are marked by poverty. The data utilized for the analysis were obtained through a survey carried out in the 1986-1987 harvest season, in which 591 migrants working in 13 ejido or privately-owned productive units in the municipalities of Tapachula and Union Juarez were interviewed.

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 describes the historical evolution of five populations and analyzes the circumstances under which data on maternal and paternal orphanhood of couples at the moment of marriage were collected and compiled." The data, which concern historical populations in Mexico, Chile, Peru, Brazil, and Argentina, are used to construct life tables for male and female adults. Consideration is given to mortality differentials by sex. (summary in ENG), (excerpt)
