LA Times:

A lower percentage of Mexican workers in the U.S. is sending money to family members back home, a report showed Wednesday.

The percentage of workers who regularly sent remittances home fell to 64% in the first half of 2007 from 71% in the same period last year, the Inter-American Development Bank said in a study of remittance patterns.

I'm guessing their families came to join them here, so no need to send the money back anymore. 9% of Mexican-born citizens had moved here by 2004, and all estimations say that rates of immigration have been increasing since then.

"This means that over the past years 2 million people in Mexico have lost a vital lifeline," he said. Mexico is the primary destination for U.S. immigrant remittances.

Or that 2 million or more Mexicans have now moved to the US. The article also states that remittances to Central America are up. I guess, using their logic, it must mean that Central Americans here suddenly got more generous -- not that their numbers increased.
