18. Name That Key Term

19. A person who is outside his or her country due to a well-founded fear of persecution and who is unable or unwilling to return. Refugee A permanent change in residence to outside one’s community of origin. Migration A move across international borders. Movements of ideas, information, money, products, and people between places. Spatial Interaction Immigration A well-defined migration channel from a specific origin to a particular destination. Migration Stream Migration that runs opposite to a migration stream. Migration Counterstream

20. Reasons to move from a particular place. Push Factors Reasons to move to a particular place. Pull Factors The percentage gain or loss of population due to migration. It is calculated as in- migrants minus out-migrants divided by the total population, all times 100. Positive numbers indicate net gain; negative numbers indicate net loss. Net Migration Rate The tendency for certain types of people to migrate. Age, education, and other sociodemographic characteristics are ________ factors. Migration Selectivity Money sent by immigrants from host country to home country. Remittances

21. A model to predict spatial interaction, where size (population) is directly related to interaction and distance is inversely related to interaction. Gravity Model The declining intensity of an activity with increasing distance from its point of origin. Distance Decay
