Moreover migrants' remittances from the United States has grown rapidly over the last two decades. In 1990, total migrants' remittances were $11.9 billion and by 2000, it equalled $30.9 billion. Between 2000 and 2009, remittances grew at an annualized rate of 5 percent.
Of the $48.4 billion in remittances, CBO wrote:
"$38 billion was personal transfers by foreign-born residents in the United States sent to households abroad, and the rest, about $11 billion, was the compensation of employees who were in the United States for less than a year."
It should not come as a shock that Mexico was the top destination for remittances with $20 billion.
The CBO found that the fee for remittances are declining. The key drivers for the lower transaction fees were technological progress and greater awareness among migrants about alternative ways to remit funds. The study reported that between 2001 and 2009 fees fell at a rate of 5.5 percent per year and 9.9 percent per year to Mexico and Columbia, respectively.
