Every year, millions of people who are living abroad send money back to their families. Immigrants and expatriates who have left their home countries for brighter futures are working hard, and send some of their money back to their home countries to help their families. These international money transfers are called remittances - when people send money overseas to their home countries to help support their families etc. Remittances are an important source of income for countries and their citizens. One of the most popular countries to send money to is India, with foreign remittance to India being an astounding $80 billion in 2019.
