Americans may have been gravitating toward big cities in recent years but that's even more true for those who have come to the country illegally, a new analysis of census data finds.
Pew Research Center says in a new report that 60 percent of the unauthorized immigrants to the U.S. live in one of 20 metropolitan areas. For context, those cities are home to 36 percent of the overall population.
Pew's research comes from numbers in the 2014 American Community Survey put together by the U.S. Census Bureau.
New York City and Los Angeles were the two metro areas where the number of unauthorized immigrants is estimated to be over 1 million. In all other cities the number was less than 600,000.
Houston, Dallas, and Miami rounded out the top five in the total number of people.
Percentage-wise, people who came to the U.S. illegally make up 3.5 percent of the country's population, researchers say.
Pew looked at 155 cities and found four where unauthorized immigrants are estimated to be more than 10 percent of the population: Yuma, Arizona; Salinas, California; McAllen, Texas; and Gainsville, Georgia.
What about the Twin Cities?
Minneapolis-St. Paul was the only Minnesota metro area included in Pew's research.
While the Twin Cities are the 16th largest metro area in the country, they were 25th in the number of unauthorized immigrants.
The estimated 85,000 people who arrived illegally represent 2.3 percent of the Twin Cities population, Pew says.
Last year Pew did a similar study focusing on states. It estimated that Minnesota is home to 100,000 unauthorized immigrants, which would be just under 2 percent of the state's population.
