>> Over the past three decades, hundreds of towns in Mexico have become dependent on dollars sent back by relatives in the US. But now the future looks uncertain. I'm Michael O'Boyle with Reuters News. I'm standing in Ixmiquilpan, Mexico. It's a small town about three hours from the capital.
And here the dollar is king. There are about 20,000 migrants who left this valley and now live in the United States. Most of them are in Clearwater, Florida, and they send home $100 million every year. This money is a crucial part of the economy. And if US president-elect Donald Trump makes good on his campaign promises to block these remittances or begin to deport undocumented migrants out of the United States, the locals here fear their economy could be crushed and that crime could rise.
From there, I also spent time in the community of Capula, which relies heavily on all the money sent home from migrant relatives in the US. Monica Arroyo here is helping prepare this food. Her daughter lives in the United States. And she needs the money that her daughter sends home in order to be able to pay for food, to pay for clothing, to help support her aged mother.
The valley is also littered with US-style homes. These were built using money from the migrants, many of whom never returned. Their nearly-finished homes are overrun with weeds and animals. To get a fuller picture of remittance flows, I also traveled to the US. Many migrants from Capula work in hotels, restaurants, and construction.
Following Donald Trump's victory, some are now going back to Mexico. Others are scrambling to arrange birth certificates for their US-born children. I'm standing in Clearwater, Florida, on Drew Street. It is sort of a heart of the Mexican community here. There are dozens of Latino-owned businesses along this street and in the area.
Now many of the migrants who live here are undocumented. I've spoken to families who are saving their money in case they need to flee mass deportation raids. I've spoken to tellers at wire transfer businesses who say some migrants are sending much more money home now in case they do need to flee.
Since winning, Trump has softened his tone, saying he would focus on deportations of illegal immigrants with criminal records. But his threats from the campaign trail are still ringing in the ears of Mexicans on both sides of the border.
