In many cases the pattern of overurbanization and the creation of
primate cities is a consequence of a colonial past. When countries were
colonized, an urban infrastructure was developed in only a select number
of locations while the interior was left to be exploited for its natural
resources alone. Over time, the primate city became a magnet drawing
huge numbers of people off the land and into the city in the hope of
obtaining some measure of wealth. Despite the abandonment of colonial
regimes, overurbanization remained as a process and continues to this
day.
