Remittances refer to money sent by foreign workers to individuals in their home country. In 2013, global remittances totaled over $500 billion USD. India is the largest recipient of remittances, receiving an estimated $70.4 billion USD in 2014. Remittances make up a significant portion of many developing countries' GDPs, with some countries relying on remittances for over 30% of their GDP. Russia's economic crisis poses a threat as countries that rely heavily on remittances from Russian workers could lose over $10 billion collectively in 2015.
