The amount of money being sent by migrants across the entire world reached $530 billion last year, making it a larger economy than Iran or Argentina, the data from the World Bank showed.

This worldwide figure has tripled in the last ten years and is now three times bigger than the total aid budgets given by countries around the world. It has sparked debate whether this so-called remittance money could be a viable alternative to relying on help from other governments.

In the United States last year, more than $120 billion was sent by workers to families abroad – making it the largest sender of remittances in the world. More than $23 billion went to Mexico, $13.45 billion to China, $10.84 billion to India and $10 billion to the Philippines, among other recipients.
