Migration is the movement of people
It is classified by such indices as Distance travelled
Reason for travel
Period of time of travel
Volume of migrants Cosequences of migration include
Increased animosity between people of different cultures
Changes in numbers of people at the destination and origin
Creation of ghettoes in urban areas
Each current has a compensating counter-current in the opposite direction.
Both currents dispaly similiar characteristics
Long distance movements are directed towards great commercial centers.
People in urban areas migrate less than people in urban areas.
Additions to These Laws Most migrants are between 20-34 years of age.
People mainly move for economic reasons.
Urban housing development is inadequate for the influx of migrants so ghettoes/shanties are formed. Zipf’s Inverse Distance Law The volume of migrants decreases with distance from the origin.
Stouffer’s Law of Intervening Distances The number of migrants moving from one town (i) to another (j) is directly related to the opportunities available at j but inversely proportional to the number of intervening opportunities between i and j. Push-Pull Theory Any migration is as a result of push forces at the origin and pull forces at the destination. Examples of push forces are famine, war and poverty. Examples of pull forces are availability of food, peace and wealth. Gravity Model This theory states that larger towns are more attractive to immigrants than smaller towns Consequences of Migration These can be subdivided into 3 categories: Demographic Consequences: Changes in the numbers and distribution of people within a region are changed. Intermarriages are created, leading to a new group of people. Social Consequences: Migration brings different people together leading to conflicts.
Migration however also creates understanding between different groups of people.Rural-Urban migration creates ghettoes in cities. Economic Consequnces: This depends on the “quality” of the migrants and the economic needs of the origin and destination. Quality refers to skills, age, educational attainment, health etc.
In underpopulated areas, emigration may slow down development.
