Know _the volume and structure of a population facilitates decision making in terms of public policy, therefore, for each territorial entity it is necessary to know the characteristics of its population, to plan and quantify the demands of goods and seNices (health, education, employment, etc.) in the short, medium and long term. The interest of this work, beyond carrying out an exercise that results in the projection of the volume and structure of the population, is to analyze the consistency of the official population projections produced by the National Administrative Department of Statistics -DANE, in the light of behaviors obseNed by different sources of information, also official, but that seem to have differences with the demographic dynamics expected in the population calculations of DANE, without ignoring that any long term projection is uncertain in terms of volume and structure. This document presents an analysis of the three fundamental components of the demographic dynamics (fecundity, mortality and migration) of the city of Bogotá, with information from different sources, which are used in the following chapters as an essential input for the calculation of scenarios of population projections between the years 2006-2020.

El presente trabajo de investigación plantea un análisis descriptivo-retrospectivo de la Mortalidad Infantil (MI) y del Bajo Peso al Nacer (BPN) ocurridos en los conglomerados de comunas en el municipio de Santiago de Cali en los años 2011- 2014, desde la relación de factores sociodemográficos, combinándolos con las variables específicas de ambos eventos: lugar de residencia de la madre, afiliación al régimen de seguridad social, el número de consultas prenatales, intervalo 1ntergenésico, tipo de parto, multiparto y primigestante; y que sea un referente útil para la toma de decisiones dentro de los procesos de planificación del desarrollo.

La mortalidad prematura por accidentes de tránsito, según la Organización Mundial para la Salud (OMS), en su informe del año 2013 refiere que la mortalidad por accidentes de tránsito deja más de un millón de pérdidas humanas al año. Para Colombia según el ministerio de salud los accidentes de tránsito son la segunda causa de muerte violenta en el país. De igual forma los accidentes de tránsito son considerados un problema de salud pública, ya que tiene efectos a nivel individual, familiar y social. Los accidentes de tránsito que dan como resultado la muerte o algún tipo de discapacidad generan pérdidas económicas, lo que influye directamente en la productividad y desarrollo del País. Este estudio pretende caracterizar y dar a conocer el comportamiento de la mortalidad prematura por accidentes de tránsito en Colombia para el periodo 2005 – 2013, a través del análisis de los Años de Vida Potencialmente Perdidos (AVPP) los cuales son una medida utilizada en la demografía y de gran ayuda en salud pública, ya que permite monitorear el comportamiento de la muerte prematura y refleja el grupo de edades más afectadas según la esperanza de vida al nacer por determinado evento. Adicionalmente, este estudio puede ser un insumo importante para movilizar acciones ya sea desde salud pública u otros sectores que permitan aumentar la esperanza de vida en la población o mitigar los efectos que el evento produce en la sociedad en general. Ya sea con la contribución como dato de interés para los tomadores de decisiones, o para el fortalecimiento de la política pública existente, y de esta manera, aportar a la generación de cambios culturales que coadyuven a la reducción de la violencia vial. La observación retrospectiva de tasas, e índices de AVPP de la mortalidad por accidente de tránsito, estimadas para el periodo mencionado, se complementa con el uso de otras herramientas como el análisis socio-espacial, a partir de los datos obtenidos de las mortalidades por accidentes de tránsito en el registro de estadísticas vitales del DANE y la base de accidentes de tránsito del Ministerio de Transporte, en donde se evidenció, entre otros hallazgos, el continuo crecimiento de las tasas crudas en departamentos como el Casanare o el efecto contrario con una disminución constante en el departamento del Quindío, y, tantos otros datos de interés comparativo para regiones, las cuales comparten la normatividad desde las esfera nacional e internacional. Además, el análisis permite evidenciar el incumplimiento de metas de las políticas públicas propuesto para el periodo estudiado, algunas aún vigentes para el año 2017, dado que los datos muestran el aumento en la tendencia de la accidentalidad y mortalidad, ya sea por actor en la vía afectado (motociclista y peatones), o la edad, entre otra cantidad de datos de interés, que nutren los procesos de discusión sobre la problemática en el país. Finalmente llamar la atención sobre los datos de la muerte prematura que afecta principalmente a los jóvenes de 20 a 34 años del sexo masculino y que el actor en la vía más afectado durante el periodo evaluado es el peatón, con algunas diferencias mayoritariamente en la costa atlántica colombiana, lo que amerita una serie de acciones con efectos rápidos para mitigar la mortalidad prematura.

The development of any region is mediated by the different interactions presented among these population dynamics: the environment, the society, the polulation and the economy. The municipality of Ayapel located in Cordoba, harbors one of the biggest swamps in Colombia, which has been essential to the development ofthis place. This paper named "lnteractions Between Enviromental And Demographic Dynamic Of Ayapel Municipality And Their lnfluence In The Quality OfThe Water In The Marsh Of Ayapel During 2007-2016", intends to show how the interaction ofthese population dynamics affects the quality of water in the swamp. The methodology used to achieve the porpuse was mainly focused on the BIT PASE model, as welI as different sources such as census, vital statistics, popuiation projections and social actors, which are key for the development of the territory, showing that there are tensions with a greater impact on the quality ofthe environmental system of the marsh. The places where many inhabitants have settled down, the livestock production, the inundantions, deforestation, the illegal exploitation of gold, are sorne of the decisive factors of these tensions.

The purpose of this research is to recognize the sociodemographic characteristics of women in each type of household and the changes they have had between 2000 and 2015 in Colombia, based on data from the National Demography and Health Survey. The document is structured in seven chapters: background and the conceptual framework are presented in Chapter 1; followed methodology is described in Chapter 2; from 3th to 6th Chapter, each chapter answers an specific objective set out in the research project, therefore each chapter includes its results, discussion of the results and conclusions; in Chapter 3, the type of household at national and regional level is stated; in Chapter 4, sociodemographic characteristics of women are presented; in Chapter 5, the type of women's unions at national and regional level are described; in Chapter 6, it is changes in the fertility of women in Colombia, according to the type of household are stated. Finally, in Chapter 7 are concluded our findings.

The border area of Cúcuta -Bolívar- San Cristóbal is a deeply dynamic space in which population, social, economic and environmental relations are articulated, built and sustained by the communities settled in this territory and that in turn transform the population group and its demographic dynamics. However, a lack of awareness of how this demographic dynamic is influenced by changes in other dimensions of development, both in the country itself and in the neighboring country, changes conditioned by social and economic population flows. Second, there is an absence of a holistic and integral approach in the studies of the border area of Cúcuta, Bolívar and San Cristóbal, which has been unknown as an integral unit in ali dimensions of development, and finally in third place it does not know how far these dynamics are influenced by the national contexts, of different kinds of tensions, and whose non-resolution leads to critica! situations that negatively affect the population of both territories and their possibilities of development. In this context, the document propases an integrative view of this geographic space, as a basis far implementing new methodologies for the reordering of these territories.

This work relates to the debate between direct subsidies and territorial development. lt seeks to provide empirical (econometric) evidence to identify the territorial components of wellbeing and to establish how the environment should become a subject of intervention, particularly in the policy as to victims of torced displacement. To reach this objective, this work compares the socio-economic conditions of the people who moved between 2005 and 201 O and their situation three years later; the conditions ofthe displaced population in the host municipalities are also compared with those ofthe voluntary migrant and non-migrant population; and a model is identified to identify the territorial and socio-demographic factors of wellbeing. The results show that certain conditions in the environment have a greater influence than the socio- demographic characteristics of households and that territorial development is essential to reduce the dependence of the displaced population on state aid and thus reduce the tax burden of assistance to the displaced population .

lntroduction: A poor nutritional status affects the population and involves very different problems, it determines from the intrauterine lile a greater susceptibility in the earíy ages, metabolic disorders in adulthood and higher risk of death also for the elderly; effects that bring impacts in social, economic, educational, among others. Objective: To characterize the premature mortalrty dueto malnutrition in Colombia and its departments in the period 1999 - 2013, identified its magnitude through the YPLL indicator. Method: Descriptive research, analyzing ICD-10 codes of vital statistics for !he years 1999. 2013, estimating mortality rates, YPLL and YPLL rates. Results. Premature mortality due to malnutrition decreases in the first years of study; from 2007 to 2013 maintains a steady behavior. There are two age groups that concentrate the highest rates, those under 5 years and those over 70, the latter with the highest rates. The departments of the Amazon and Orinoquia show limitations in estimating indicators, attributed to sub-registration, coverage, census ornission, among others. The departments of the Caribbean Coast and Choco have the highest mortality rates and YPLL ratas for malnutrition.
