This video of the national anthem of Colombia contains good examples of home-based (informal) activities. It depicts a typical afternoon in Santo Domingo, one of Medellin’s poorer neighborhoods. People are involved in different productive activities, such as simple manufacturing and retail selling.
Dense neighborhoods are typically very lively, and many people conduct their occupations near or at their homes. In my current research I am trying to incorporate these features of cities in developing countries in order to understand the link between commuting patterns and job status.
