The document discusses different types of human migration. It defines internal migration as movement within a country's borders, while international migration involves crossing country borders. The types of movement include cyclic, which involves returning home, and periodic, which involves longer periods away from home. Migration can be forced due to issues like armed conflict or natural disasters, or voluntary for reasons like job opportunities, marriage, or cultural preservation. Common destinations for migration are areas with economic prospects, cultural groups, or safety from political instability or war. Guest workers and refugees are also discussed.
