A slum is a place which forms a cheap way to dwell, mostly for the large stream of people going from rural areas to the large cities to find a job.
This migration movement is triggered by the evolvement of a global network which triggers large companies, which generate all kinds of activity to transportation nodes (places where man can easily travel to, preferably by use of different flows of transportation). This global network draws attention to cities, which are often well connected to such a network (airports, large train- and bus stations), which can be noticed both in the explosive way cities are expanding and the enormous economic boost which urban areas are given. This process has been initiated by the development of technology and accordingly, society.
It is roughly what can be described as the process man refers to as globalisation.
This process creates the stream of people to cities, who are not able to afford regular dwelling, and therefore live in slums, where life is reasonably cheap. One should be aware of the fact the dwellers of the slum (in the case of the larger ones) are still of great political and economic importance. For example; there are NGOs which are located in areas marked as a slum
