[Some reflections on teaching demography in Mexico in the beginning of the twenty-first century: a new focus]. / Algunas reflexiones sobre la ensenanza de la demografia en Mexico en los umbrales del siglo XXI: nuevos enfoques.

PIP: The evolution and achievements of population studies programs at El Colegio de Mexico since the 1964 founding of the first master's program in demography in Latin America are described, and topics of interest for future research are identified. In 1995 the master's program and the doctoral program in social sciences with specialization in population studies were combined into a single program. Students are trained in demographic analysis, the methods of demographic research, the processes of development, and demographic theory. The program seeks to develop multidisciplinary orientations regarding links between population processes and social and economic factors. 67 students have obtained master's degrees and 8 the doctorate. The aging of the Mexican population resulting from its relatively rapid fertility decline suggests crucial topics for future research. The survival of 3 or even 4 generations, the reduced number of siblings, and other changes in family structure and relationships may generate research. Topics related to old age security for women, the effects of AIDS, internal and international migration patterns, and the demographic processes of the indigenous population are other significant topics. New employment opportunities in addition to the two traditional areas, academia and the public sector, should be sought for demography graduates in business and industry and in regional educational and planning centers.^ieng

[The future population of Latin America]. / La poblacion futura de America Latina.

PIP: Latin America has a population of 471 million, which grows at a rate of around 2% per year; if this does not change, the population will double in a period of 35 years. Life expectancy at birth was 68 years in the period 1990-1995, it will be 73 years in the period 2020-2025, while the global birth rate of 3.1 in 1990-1995 will be reduced to 2.2 in 2020-2025. In the year 2000 the area will have a population of 510.9 millions and in 2025 it will increase to 686.4 millions; 23.9% will be under the age of 15 years, 67% will be aged between 15 and 64 years, and 9% will be aged 65 years or over. These figures show the quick process of aging in the area's population as a result of the decrease in births. The region will face two fundamental demographic problems at the beginning of the third millennium: the aging of the population and the rapid increase of the working-age members of this population.

[Reconciling population censuses with birth, death, and migration statistics through an expolinomial function]. / Conciliacion de la poblacion de los censos y las estadisticas de nacimientos, defunciones y migracion a traves de una funcion expolinomial.

"This study seeks to build a mathematical function, which has been named expolinomial, to describe total population dynamics in Mexico between 1940 and 1990. It also aims to carry out an analysis to reconcile data from population censuses with birth, death, and migratory data." (SUMMARY IN ENG)

[Adjustment of an expologistic function to the evolution of Mexico's total population, 1930-1945]. / Ajuste de una funcion expologistica a la evolucion de la poblacion total de Mexico, 1930-1985.

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."
