Why do people move to new places?

There are a lot of reasons for this. Sometimes people have to move because of a job or to attend a certain school. Sometimes people want to live in new places so they can learn about other people and other cultures. Sometimes they move so they can be closer to friends or family. Sometimes they move to avoid people (for instance in the Witness Protection Program). Sometimes people move for health reasons, or weather/climate reasons, or because a certain area is the best place to be if you want to pursue a certain career. Some people just want a change, or to escape their own past.
