Top 100 corridors with the highest remittance flows worldwide 2021

Remittances between the United States and Mexico were over twice as large in value as the second-biggest corridor, which was in Asia. This is according to a Statista ranking, using a table that tried to map out migrant remittance flows between individual countries. Multiple countries across the world received remittances worth more than three percent of their GDP in 2022. That said, it should be stressed that remittance figures are not without their flaws. First, the numbers shown here are based on migrant stock. This is a difficult topic to track for certain countries, but also potentially excludes other types of remittances - such as pensions or illegal remittances. Two, the figures essentially assume that every migrant will send the difference of per capita income in PPP terms back home to the country of origin. The source acknowledges this is a rough proxy, potentially leading to over- or undervaluing any estimates.
