Because emigrants bring with them more than just economic needs from their home countries, migration is a trade stimulant in and of itself. With this movement, there is increased demand for housing, food, transportation and other services which are beneficial to local economies.
In addition, migrants can serve as bridges to a wider market because they promote trade and tourism in their home countries, thereby creating demand.
The diaspora population's needs can be met if the African economy is stimulated by the trade-in African heritage. While there are many reasons for migration, one of the most important is joblessness, both within Africa and to other parts of the world.
