majority of migration in the world is from the countryside to
towns and cities, with the largest migration currently occurring
in the South. People leave rural areas to seek employment in
urban areas, but they often experience considerable difficulties
in their new environment.
people also emigrate to other countries to seek a better life,
although this may not always be for economic reasons. It could
be to escape war or persecution, or to join family members. This
movement can also present problems, from language differences
through to racism.
