Why do people move?
There are many, many reasons. Some people move because they are poor and can't afford the expenses in the place they are living in. They might move because they want more land, money and freedom like the immigrants who came to America did. Some people might move because there is war in their country or because of their jobs. People move because they want better education, a cleaner environment and a healthier place to live. People like to experience different places and therefor they move into other places.
