In Latin America the eighteenth century was a time of approximate doubling of the population and considerable economic development and reorientation of the economy. Urban settlement reflected these changes. The bulk of urban growth was by replication of existing patterns into areas of new settlement. Some expansion of older cities and heightening of urban functions took place. In the reordering of regional economies, Buenos Aires, Havana, and Rio de Janeiro profited; Lima failed to prosper. Within existing and new cities, much building replaced older structures in more durable materials, and, in the largest, multi-family, multi-storied structures appeared. Following developments in Europe, beginnings were made in paving streets, providing lighting, installing drains, and so-forth. In similar wise, administration adopted new forms and social welfare was reorganized for more efficient response to natural disasters. Cultural models, copied from Europe, even included the beginning of cafés.

Los objetivos más importantes de esta investigación son los siguientes: 1) comprobar la hipótesis de que el crecimiento de las ciudades también puede medirse valiéndose del análisis de los datos que se pueden extraer de los avisos publicitarios de las empresas que prestan servicios relacionados con el ámbito inmobiliario y que aparecen en las páginas amarillas en papel y virtuales; 2) comparar los resultados de estos datos con las cifras de población, viviendas, superficies urbanas, PIB y censo catastral inmobiliario. Para ello se extrajeron los datos del directorio de Bogotá de los años que permitieran compararse con las fechas en las que se llevaron a cabo los últimos censos de población y vivienda (1993 y 2005), y también para 2008, a fin de que el panorama fuera más reciente; también se tomaron los datos de las páginas amarillas virtuales de algunas de las más importantes ciudades de Latinoamérica, para el año 2009. En el caso de Bogotá se comprobó que su crecimiento urbano es directamente proporcional al del número de empresas inmobiliarias, y en el de algunas ciudades de Latinoamérica se corroboró que sucede prácticamente lo mismo. En suma, se pudo concluir que analizar estos datos es una opción importante para medir el crecimiento urbano, por lo menos para las últimas dos décadas, pero también un indicador innovador para monitorear el crecimiento de muchas ciudades del mundo que publiquen páginas amarillas virtuales. AbstractThe main objects of this research are given below: 1) prove the hypothesis that city growth can also be measured by using the analysis of data extracted from real estate companies’ advertisements, published in the paper and on-line versions of the Yellow Pages; 2) compare the results of these data with population, housing, urban area, GDP and real estate land census figures. To this end, data were obtained from the Bogotá directory for the years that permitted a comparison between the dates when the last population and housing censuses (1993 and 2005) were carried out and 2008, to provide a more recent overview. Data were also taken from the virtual Yellow Pages of certain major Latin American cities in 2009. In the case of Bogotá, urban growth proved to be directly proportional to the number of real estate firms, as it did in a number of Latin American cities. In short, analyzing these data is an important means of measuring urban growth at least for the last two decades. It is also an innovative indicator for monitoring thegrowth of many cities in the world that publish virtual Yellow Pages.

Abstract Objective: Using newly harmonised individual-level data on health and socio-economic environments in Latin American cities (from the Salud Urbana en América Latina (SALURBAL) study), we assessed the association between obesity and education levels and explored potential effect modification of this association by city-level socio-economic development. Design: This cross-sectional study used survey data collected between 2002 and 2017. Absolute and relative educational inequalities in obesity (BMI ≥ 30 kg/m2, derived from measured weight and height) were calculated first. Then, a two-level mixed-effects logistic regression was run to test for effect modification of the education–obesity association by city-level socio-economic development. All analyses were stratified by sex. Setting: One hundred seventy-six Latin American cities within eight countries (Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Mexico and Peru). Participants: 53 186 adults aged >18 years old. Results: Among women, 25 % were living with obesity and obesity was negatively associated with educational level (higher education–lower obesity) and this pattern was consistent across city-level socio-economic development. Among men, 18 % were living with obesity and there was a positive association between education and obesity (higher education–higher obesity) for men living in cities with lower levels of development, whereas for those living in cities with higher levels of development, the pattern was inverted and university education was protective of obesity. Conclusions: Among women, education was protective of obesity regardless, whereas among men, it was only protective in cities with higher levels of development. These divergent results suggest the need for sex- and city-specific interventions to reduce obesity prevalence and inequalities.

In recent years, urban design development has been an important topic in Latin American cities such as Medellín due to the transformation of their urban spaces, along with the new methods used to evaluate the social, morphological, and, in some cases, economic impacts that have been brought about by the urban development projects. When inquiring about the development process and impact of urban studies, and the inhabitants’ relation to a transformed space, it is important to establish the context within which images, drawings, and photographs are analyzed, using graphical approaches triangulated with other research methods to define comparative criteria. In this article, we reflect on the expanded use of various research tools for the analysis of urban transformation, taking with reference the experience lived by a group of researchers in two Latin American cities. From this, it is intended to understand how they work and how they allow us to understand the urban transformation of these cities, the data obtained, and the vision of the researchers.
