29. RAVENSTEIN’S LAWS
Ravenstein’s laws allow geographers to make generalizations about migration. They ‘govern’ 3 areas:
1.) the DISTANCE of migration
2.) the REASON for migration
3.) the CHARACTERISTICS of migrants

30. Ravenstein’s laws on DISTANCE OF MIGRATION
Most migration is short-distance and within the same country.
Long-distance and international migration generally flows toward centers of economic activity.

32. Ravenstein’s law of REASONS FOR MIGRATION
Most people migrate for ECONOMIC reasons.
Political & environmental factors cause people to migrate- but not as often as economics.

34. Ravenstein’s law of CHARACTERISTICS OF MIGRANTS
Most long-distance migrants are MALE.
Most long-term migrations is by INDIVIDUALS, not by families or other groups.

36. United Nations High Commission for Refugees (UNHCR) recognizes three groups of forced political migrants.
A refugee has been forced to migrate to avoid a potential threat to his or her life, and they cannot return for fear of persecution.

37. An internally displaced person (IDP) is similar to a refugee, but they have not migrated across an international border.
Largest number of refugees in 2010 was forced to migrate from Afghanistan and Iraq because of war.

38. An asylum seeker is someone who has migrated to another country in hope of being recognized as a refugee.

39. All of these terms differ from the more general name ‘MIGRANT,’ which refers to someone who has chosen to leave their home in search of a better life.
REFUGEES are granted special protections in many countries, while MIGRANTS are often given a far less warm welcome.
