The developing world faces many significant social and economic challenges. These include tackling poverty and disease, reducing crime, and creating the infrastructure and security needed to foster economic prosperity and create jobs.

Many parts of the world also rely on the goodwill and financial support of charitable organizations and private individuals. Two other types of international giving are significant: international philanthropy; and money sent home by migrant workers as remittances.
