Tendencias y proyecciones de la fuerza de trabajo del Área Metropolitana del Valle de Aburrá, 2010-2030 Jorge E. Horbath Estudios Territoriales Demografía mercado de trabajo áreas metropolitanas Las proyecciones de la fuerza de trabajo constituyen el ejercicio demográ - fico más cautivador y más complejo de realizar, dados los fenómenos imbricados en dicho proceso. Destacan al respecto aquellos vinculados a los cambios generacionales, específicamente el paso desde población en edad infantil a población en edad de tra - bajar, y posteriormente a población económicamente activa. Al realizar tales proyec - ciones para el Área Metropolitana del Valle de Aburrá (la principal área metropolitana de Colombia), se encuentra una gran dinámica económica entretejida con otros fenó - menos sociales, como la violencia y la presencia de jóvenes que ni estudian ni trabajan (conocidos como “Ninis”), junto a cambios territoriales de distintas tendencias en las zonas tanto urbanas como rurales de Medellín, y en los municipios que integran el área. En particular, este artículo muestra las proyecciones de población y fuerza de trabajo en el marco del proyecto Plan Director BIO-2030. 2015 artículo científico 0250-7161 https://www.redalyc.org/articulo.oa?id=19637101010 es http://www.redalyc.org/revista.oa?id=196 EURE application/pdf Pontificia Universidad Católica de Chile EURE (Chile) Num.123 Vol.41
