In 2022 migrants sent home nearly $800bn, according to data from the World Bank. Around 80% of these remittances were sent to low- and middle-income countries. India received $100bn; Mexico got $60bn. Remittances were the biggest source of capital inflow for low- and middle-income countries in 2022, exceeding foreign direct investment and aid. Their importance is growing. In 2023, global remittances are expected to increase to $815bn. Can that money help drive growth in recipient countries?
