Social and economic imbalances in the metropolitan area of Monterrey

The paper describes social and economic differences between Monterrey’s eight municipalities, including housing conditions and basic service provision, and how these changed between 1970 and 1990. It also describes the social and economic differences for 1990 between the 710 micro-areas into which Monterrey was divided, which allows a more precise and detailed picture of intra-urban inequalities. It also reveals the limitations of an intra-urban analysis based on municipal boundaries by showing many clusters of micro-areas with very low levels of socio-economic development in some of the better off municipalities.

Los polos dinámicos de la industrialización : la industria moderna y la industria maquiladora : Nuevo León : 1988-1995

El artículo analiza los efectos del modelo macroeconómico de apertura comercial sobre la competitividad, las empresas y el empleo en la industria moderna y en las maquiladoras de la Zona Metropolitana de Monterrey. El estudio demuestra que dicho modelo se sostiene en estos dos polos de crecimiento industrial de la región, y se caracteriza por el crecimiento de la producción, las exportaciones y la generación de empleo. El trabajo subraya que el crecimiento del empleo es diferenciado; muy dinámico en la maquiladora y muy lento en la industria moderna. Asimismo, resalta que ambas industrias son portadoras de ofertas sociales antagónicas. La industria moderna, aunque con lento crecimiento del empleo, produce fuentes de trabajo calificado y altamente remunerado; por el contrario, la industria maquiladora, con una oferta dinámica de empleos, produce puestos de trabajo que no requieren calificación y que son retribuidos con salarios mínimos. La reflexión final del trabajo se centra sobre la interrogante ¿cuál de ambas tendencias será la dominante en la futura industrialización de Monterrey?

Reproducible and predictable yearly pattern in the incidence of uterine cervical cancer.

A yearly pattern in the occurrence of uterine cervical cancer (UCC), obtained from cytological examinations reported as type V (cases concluding a malignant alteration), has been previously shown for data obtained in the Monterrey Metropolitan Area (state of Nuevo Leon, Mexico) for a span of 10 years (1978-1987), with a peak of relative incidence in the month of February being high stable for consecutive years. With the aim of extending and validating those results, we analyzed the monthly totals of positive detected cases of UCC in the states of Nuevo Leon, Chihuahua, Coahuila, and Tamaulipas (covering most of Northern Mexico) during the same period. To eliminate bias due to the seasonal variation in the number of screening smears, data were first expressed in relation to the number of cytological examinations done the same month. The least-squares fit of a 1-year cosine curve to the data of relative incidence in the four states reveals a statistically significant yearly pattern (p = .008), with a maximum of relative incidence in February almost double that during the rest of the year. Results indicate that the relative incidence of UCC is higher than the yearly average during the winter, with secondary peaks in May and October. In view of the nonsinusoidal waveform in the incidence of UCC, we undertook a multiple-component analysis, allowing several cosine functions to be simultaneously fitted to the data. Results indicate that the yearly pattern in the relative incidence of UCC can be represented by a model that includes two components with periods of 12 and 4 months (p = .004). The same model can be documented as statistically significant independently for each of the four states. These results, summarizing over 2200 positive cases of UCC detected in more than 1,100,000 screening smears, are in full agreement with those found previously for part of the state of Nuevo Leon and reveal a highly stable and predictable yearly pattern of variation in the relative incidence of UCC in Northern Mexico.

Gene frequencies and admixture estimates for ABO, Rho (D), and MN blood groups in persons with mono- and polyphletic surnames in monterrey, N.L., Mexico.

A sample of 3,211 males and females insured by the Instituto Mexicano del Seguro Social (I.M.S.S.) residing in the Monterrey Metropolitan Area (MMA), northeastern Mexico, were selected by their monophyletic or polyphyletic surnames. ABO, Rho (D), and MN blood groups were determined, and phenotype and gene frequencies were estimated to study the genetic variation among populations with these surnames, to estimate the genetic contribution from their most important ancestral populations, both Spanish and Mexican Indians, and to compare genetic structure with other populations that have been reported from this MMA and other urban centers in Mexico with the hypothesis that the persons with monophyletic surnames are the closest descendants of the founders, who colonized the MMA between 1577 and 1596, and that they still conserve some degree of genetic isolation. The results indicate that the selected persons with monophyletic surnames are the closest to the Spanish, supporting the above hypothesis; on the other hand, persons with polyphyletic surnames are the closet to other Mestizo populations from central Mexico and the Mexican Indians. Hybrid persons with one monophyletic and one polyphyletic surname are closer to the monophyletics due to the fact that 90% of these polyphyletics originated in northeastern Mexico. It is concluded that, at present, the Mestizo population from the MMA is integrated by two subpopulations, one with monophyletic and the other with polyphyletic surnames. It is suggested that due to an increase in migration in Mexico, the Mestizo genetic structure of the MMA population will slowly become more uniform. © 1995 Wiley-Liss, Inc.

Trabajadores migrantes en el área metropolitana de Monterrey

"In this article, an analysis is made of evidence regarding the metropolitan area of Monterrey, [Mexico]....[A] study carried out in 1965 is used as a point of reference, and information is analyzed for 1980 and 1983. In the first section of this article, a brief summary is provided of some of the recent contributions that have been made to the study of the profitability of internal migration. The second part is devoted to an analysis of the 1980 and 1983 surveys, focussing on the features distinguishing recent migratory workers and the rest of the work force...and on the factors determining income, with special interest in the category of migrants....Lastly, a summary of the main findings is presented."

Jerarquía de centros según flujos de personas en el área metropolitana de Monterrey

El propósito de este trabajo es investigar si en la actualidad existen uno o más subcentros que desconcentren las actividades comerciales y de servicios en el Área Metropolitana de Monterrey (AMM). Para ello se aplica la técnica de Nystuen y Dacey (a través de la cual se recurre a la teoría de grafos para la identificación de regiones nodales). Utilizando la información proveniente de una encuesta de origen y destino de pasajeros, realizada en 1981 en esa área metropolitana.El trabajo explica cómo se ha utilizado la técnica de análisis y describe, asimismo, los resultados de su aplicación. Se llega a la conclusión de que todas las zonas en que se divide el AMM están subordinadas al centro principal, lo cual demuestra que se trata de una ciudad muy centralizada, con un subcentro ya consolidado y otros dos subcentros incipientes. Se termina afirmando que el AMM se encuentra inmersa en un proceso de transición de una ciudad monocéntrica a una policéntrica, proceso que acompaña al gran crecimiento físico, demográfico y económico experimentado por la misma.

Differential Fertility in Monterrey, Mexico: Prelude to Transition?

The past 30 years have witnessed rapid and significant advances in the Mexican economy. Yet, even though mortality has fallen precipitously, recent investigators have looked in vain for signs of a transition in Mexican fertility. For the country as a whole, no decline is evident.1 Moreover, available evidence indicates that urban fertility has tended to increase in recent years even though it remains lower than rural fertility.2 Rather than signify that no transition in fertility has occurred, however, these results may indicate that the effects of modernization have not been sufficiently pervasive to be reflected at a nationwide or urban level. Since existing theory maintains that fertility declines begin in the upper educational and occupational strata of large urban areas, an adequate assessment of the possibility of a change in Mexican fertility requires the investigation of fertility differentials among socioeconomic subgroups within urban areas. This paper is a first report of such an investigation. The data are based upon a survey of 1,640 males between the ages of 21 and 60, resident in the metropolitan area of Monterrey, Mexico.3 The Monterrey metropolitan area serves as an excellent location in which to investigate differential fertility because of its size (an estimated 950,000 inhabitants in 1965) and its importance as a center of Mexican heavy industry (43 per cent of the economically
