Causes of migration

The people of Brazil migrate to other places in the country or even leave the country for several reasons ranging from attempting to escape poverty and make a better life for themselves elsewhere, to escaping persecution from an oppressive government.  The people usually are in search for a better life and the farmers in the area are moving toward the cities where life will presumably be better for them.  They do this because they have a hard time making a living or even surviving on farming.
