A new migratory horizon in Central Mexico: 1970-1990

"During the last few decades migration in Central Mexico has undergone important changes. Not only have populations been moving increasingly towards the periphery and decreasingly towards the center, but those originally living in the center are also moving to the immediate periphery. This behavior allows us to claim that Central Mexico is undergoing a process of deconcentration or suburbanization. This study describes the way in which such a process has developed and the situation of geographical entities within that process. Analysis of the new regional configuration takes into account demographic growth and the direction and characteristics of migration in the Mexico City Metropolitan Area and its surrounding states during the last twenty years."

Development and regional urbanization in Mexico, 1970-1990

"Here regional urbanization in Mexico is studied as a function of income level and production structures. This general model allows us to identify four characteristics that are inherent to urban development for the 1970-1990 period." (SUMMARY IN ENG)     

Spatial distribution of population in the metropolitan area of Mexico City, 1950-1990

"This study explores how the spatial distribution of population in the Metropolitan Area of Mexico City (MAMC) has changed between 1950 and 1990. First of all it presents the structural concepts of this research, and then analyzes the growth and spatial distribution of the MAMC population.... The results of this study indicate that MAMC: (i) continues to decrease in its central areas, (ii) presents a process of home location with expanding waves and moments of consolidation, (iii) has a many-centered metropolitan structure, and (iv) the dominating center separates progressively from the traditional center and is already located in the State of Mexico."

Assessment and adjustment of census population data:1930-1990

"This article assesses and corrects total population data by age and sex from the 1930-1990 [censuses], for nine regions in Mexico. The assessment is based on the Whipple, Myers and United Nations indexes, and the corrections were carried out with the United Nations 1/16 techniques." (EXCERPT)     

Legal international migration across the northern frontier of Mexico

The impact of the Simpson-Rodino Law of 1986, which increased legal commuting labor migration across the Mexican-U.S. border, is examined using data from surveys undertaken in 1986 and 1990. "Using these data and LOGIT regression models which include variables related to individuals as well as their household members and their context, statistical evidence is generated in support of the propositions that, i) an expansion occurred of the spectrum of social strata incurring in this type of migration; ii) the selectivity characteristics of new entrants into this migration group show a reproduction strategy oriented toward upward mobility; and iii) contextual factors led to a geographic redistribution of the commuter migrant group in the state of Baja California."

Measuring the economically active population in Mexico in the early 1990s

"This paper refers to problems of definition and measurement of the economically active population in the early nineties in different Mexican sources of information, considering in particular the 1990 Population Census and the 1991 National Survey on Employment. The study analyzes in detail the questions, reference periods, and coding systems of these two and other previous surveys and censuses. Its findings allow us to state that the 1990 Population Census is an adequate source of information for analyzing [the] national full-time salaried work force." (SUMMARY IN ENG)     

Whitehall and the Refugees: The 1930s and the 1990s

Abstract

In this paper, originally presented on the occasion of the launch of her book concerning British immigration policy towards Jewish refugees from 1933 to 1948, London compares that past with present British immigration policy and attitudes towards it. She argues, above all, that the same worry about the long-term effects of immigration—that is, that refugees would settle in the country and not return home or move on—that very much influenced the tendency to inhibit aid to Jewish refugees in the 1930s and 1940s, is still very much alive today. While the legal situation of refugees and the kinds of persecution from which they seek refuge are different in the two periods in question, the 1930s and the 1990s—there are now, for instance, international conventions on refugees to which Britain is a signatory—British immigration policies of both periods are marked by many of the same priorities and many of the same attitudes towards and perceptions of refugees. In closing, she sounds a warning that an understanding of the past, crucial as it is, should not be mistakenly used to justify a lack of humanity in the present.     

The evolution of mortality in Mexico, 1940-1980

The author analyzes mortality trends in Mexico in the twentieth century, particularly since 1940. Trends are examined according to age, sex, and cause of death. The decline in mortality is then considered in the context of the country's history and other mortality transitions. Regional variations and excess mortality are also described.

Suicidal intentions and suicides in Mexico, 1977-1984

The author examines and compares levels and trends in suicide in Mexico, using official data for 1977 and 1984. Consideration is given to characteristics of those who attempt or commit suicide, including geographic differences, method preferred, age, marital status, and reasons for wanting to die.     

Infant and child mortality in Mexico,estimated using the 1980 and 1990 censuses and projections to 2000

Using indirect methods based on information about live births and surviving children, the author reviews estimates of infant and child mortality in Mexico. Data are from the 1980 and 1990 censuses.     

The political process of decentralization in Peru, 1985–1990

This paper, using Peru as a case study, argues that the most potent factor in the implementation of decentralization in developing countries is ‘political’ in nature and operation. The legislative process of decentralization under President Alan García's regime went through three major steps, controlled by his party, APRA (Alianza Popular Revolucionaria Americana,): (1) The 1986 Bill of the Basic Law of Regionalization; (2) The 1987 Basic Law of Regionalization; and (3) The 1988 Modified Law of Regionalization. Why did Alan García push for decentralization, unlike his predecessors? The 1985 elections produced García, a populist demagogue, and a loose political party system dominated by APRA. However, the legislation of decentralization was possible paradoxically because García, who was desperately looking for a political issue to distract people's minds from his misgovernment, needed to control APRA for a regional power base after 1990. Thus, the whole decentralization process was highly politicized, and García's strategy was ‘successful’ in that regional governments came to be controlled by APRA after the 1989 and 1990 regional elections. The Peruvian case shows how far decentralization can be used for personalistic or partisan interests in a fragile democracy.     

The metropolitan character of urbanization in Mexico, 1900-1988

The author analyzes trends in urbanization in Mexico during the twentieth century, with a focus on the impact of rapid industrialization since 1982. Sections are included on the interrelations among economic development, industrialization, and urbanization; stages, levels, and measures of urbanization; the development of the city system in Mexico; and stages in the growth of Mexico City.

Avoidable causes of death and their effects on life expectancy. A socio-demographic interpretation. The case of the northern frontier, 1980-1990

"This study forms part of [a] research project on the health-disease-death process along the [Mexican] Northern Frontier--a by-product of the socio-economic structure of a specific social formation that determines disease and death--to support regional and sectorial design of policies and actions for the improvement of health conditions for its population.... An important finding is a 4.1 year increase of life expectancy due, among other causes, to a slight decrease in avoidable death causes, although these still produce about 50% of deaths."

Population-territory: 100 years of evolution, 1895-1990

The authors "describe population distribution trends [in Mexico] from 1895 to 1990 as they relate to a division of political and administrative factors. The study provides an estimate of population dispersion throughout time by analyzing the behavior of state populations with respect to the distance between state capitals and the Federal District. It also provides 100-year curves describing time variations of population dispersion and explaining the process of decentralization of displacement from the country's main population center to its peripheral areas."

Adjustment of an expologistic function to the evolution of Mexico's total population, 1930-1945

The author makes the case that none of the mathematical models currently in use for estimating population dynamics can be suitably applied to Mexico's natural growth "due to the fact that the assumptions underlying [their] mathematical representations do not correspond to the observed dynamics of the components of natural growth. The purpose of this article is to adjust a mathematical function to the evolution of Mexico's total population between 1930 and 1985, adequately reproducing the evolution of natality and mortality observed in that period."

From natural to controlled fertility: Mexico, 1950-1980

Mexico's demographic transition was much later and more rapid than the classic transitions of European populations. A careful study of available data sources, especially fertility surveys, allows a detailed understanding of the reproductive process in Mexico, including the nuptiality patterns that influence fertility as well as changes in general and marital fertility. This work assesses the data sources and methods utilized to analyze Mexican fertility in the past, reviews fertility trends before the onset of the transition from about 1940-70, and describes the new reproductive patterns observed since about 1976. Fertility information from the decinnial censuses is not very adequate for measuring fertility levels or trends. Possible estimates based on census information are few and widely scattered in time, and omissions, underregistration, and faulty declarations are common because of the retrospective nature of the census. Census information is highly aggregated so that significant intermediate variables are not easy to assess. But census data are still the only source allowing estimations of fertility levels by areas of residence, administrative entities, and their social and economic characteristics. Mexico's vital statistics are of poor quality, with underregistration and late registration common. Evaluations of the Mexican Fertility Survey (EMF) of 1976-77 indicate that it provides more reliable estimates than the vital statistics or the census. The EMF and the National Demographic Survey (END) of 1982 indicate that the total fertility rate fell by 30.3% between 1974-80, from 6.27 to 4.37. Both the EMF and the END were national level surveys which collected complete fertility histories thus providing longitudinal information on the marital and fertility histories of women aged 15-49. This work uses primarily data from the EMF and END to analyze the period of fertility increase between 1940-60, the period of highest fertility between 1950-70, and the transition from a natural fertility regime to one of fertility control after 1970. The analysis contains 2 major parts, 1 presenting a study of general fertility including age specific rates for generations and periods, final family size of women terminating their childbearing, and the calendar of fertility for women still of fertile age. The 2nd major section focuses on marital fertility using the same indicators but taking into account the relationships between nuptiality and fertility. Comparisons are included between fertility levels based on the major surveys and those implied by the census and vital statistics data.
