2. About Ernst Georg Ravenstein
Ernst Georg Ravenstein (1834 –1913) was
a German English geographer cartographer.
Ravenstein was born in Frankfurt, Germany
to a family of cartographers. Although he
spent most of his adult life in England.
He died in his birth country – Germany on 13
March 1913.
He established a Theory of Human
Migration in the 1880s
3. There is an inverse relationship
between the number of migrants
and the distance travelled,
whereby the further the distance
from the source, the less migrants
there tend to be, therefore
migrants are less likely to travel
far. This is known as ‘distance
decay’
Most Migrants move only relatively short distances.
5. People who do move long
distances tend to not be aware
of the opportunities that will be
presented to them when they
arrive, which is why they tend to
move to urban centres where it
is perceived that there are
greater opportunities
Long distance migrants head for major centers of
economic activity
6. Migrants do not tend to go straight to their end destinations.
Large towns grow by migration rather than natural increase.
Migration occurs in stages
7. This is based on the exponential growth in cities, which is
due to migration and, to a lesser extent, natural increase.
People in rural areas are more likely to migrate than
those in towns or cities.
8. Women are more likely to migrate within their country than
men.
Men are more likely to emigrate (migrate abroad) than
women.
Most migrants are adult.
Three general observations about the type of
migrants:
9. Most long distance migrants are male, adult
individuals… not families or children
