Meanwhile, citizens of Pakistan, India and the Philippines are seeking better opportunities in the booming nation of Qatar. The other mass migration occurring around the world is from South and Central America. Gang violence, corrupt governments and drug cartel problems top the list of reasons why, in countries like Guatemala, Honduras, El Salvador and Venezuela, many people decide to leave.

In fact, it is a reverse theory: we know that countries that begin to develop their infrastructure or other sectors attract more migrants because of the opportunities that result.
