This example from the World Bank International Debt Statistics shows workers remittances, or the money people send home when they work abroad. Remittances tend to be counter-cyclical, buffering other shocks, since natural disasters or economic downturns encourage additional workers to migrate abroad and those already abroad increase the amount of money they send to families left behind. Remittances now exceed official development assistance. They are set to rise further as banking restrictions are lifted and it becomes easier to send money home. You can see India has high level of remittances due to its highly educated and historically very mobile workforce. Remittances are also high for Mexico because of its proximity to the USA.
