In a statement, explain each of the measures related to South Korea listed below.

South KoreaArithmetic population density = 493Physiologic population density = 2,592Crude birth rate = 9Crude death rate = 5Natural Increase % = 0.4Replacement fertilityInfant mortality rate/ 1,000 = 5Newborn mortality rate = Child mortality rate/ 1,000 = 5Life expectancy

Male = 74 Female = 81

What is the difference between migration, periodic migration, and cyclic movement?

Identify the following as either cyclic movement, periodic movement, or migration:Commuting to a jobHunting and gathering to follow seasonally available plants and animalsMoving a flock of sheep to mountains in the summer and pasture land in the fall and springRelocating to another country for a jobA “snowbird” moving to Florida in the winter and Michigan in the summerMoving your family from Seoul to Cheonan

Give an example of voluntary migration. Give an example of forced migration. Give an example of countermigration.

What are Ravenstein’s laws of migration?

Describe the gravity model? What does it measure? How accurate is it?

How could intervening opportunities keep a migrant from achieving his or her initial goals?

What is the difference between a refugee and an internally displaced person?

Where in the world are the most refugees located? What conflicts have contributed to these situations?

Look at the image below. Chose one migration stream on the map and discuss how the stream shows distance decay. Choose another stream and discuss how the stream shows chain migration. How do the immigration policies of a government influence migration streams?
