A migration flow is the number of immigrants that cross a border in a specific period of time. These immigration crosses the border of another country because they want to stay there for a long time. The migration flow takes into consideration the number of migrants that enter or leaves a country in a year.
An example of a modern historical migration flow is the situation in the border of the United States and Mexico. Immigration is one of the most important foreign issues between these two countries. The problem is not that many Mexicans want to cross the U.S. border, but the Central American people that travel through Mexico to get to the United States illegaly. The majority of these people are from Honduras, Salvador, and Guatemala. The flow of migrants is constant throughout the year. Indeed, it is happening at this very moment.
