What is a push factor? what is a pull factor? give an example of each?

Push Factor-When people are forced out of their country because of famine (lack of food), too much trouble, ect.

Pull Factor-When people move to another country not by force but because there are more job opportunities,safer,ect.

One example of a push factor would be the potato famine the Irish experienced in 1845-1855many of their crops died and there was a lack of food.So they were forced to migrate to United States.

One example of a pull factor would be the gold rush in California 1848-1855.Many Chinese heard about the gold rush and instantly migrated to the United States hoping to strike gold and become rich.So they were pulled by the country's gold.
