The aim of this paper is to analyse the main trends in migrant remittance flows to developing countries from 1990 to 2009. Specifically, it seeks to analyse the direction and size of these flows, as well as their relationship with migratory flows and economic fluctuations during the period. To do this, a descriptive analysis was carried out based on data from the World Bank, specifically the Migration and Remittances Factbook 2011 and the Balance of Payments of the countries, published annually by the International Monetary Fund.
