The commonly held belief is that " the surge in immigration in the last two decades has overwhelmed the United States with low-wage foreign laborers." Actually, the distribution amongst low-skilled and professional workers is evenly divided, and in some metro areas such as St. Louis, predominantly white-collar.
According to a new analysis, "the 25 million immigrants who live in the country's largest metropolitan areas (about two-thirds of all immigrants in the country) are nearly evenly distributed across the job and income spectrum
The survey of 1,600 adults, which examined the reasons for anti-immigration sentiment in the United States, was published in February in American Political Science Review, a peer-reviewed journal."
In fact, "cities with thriving immigrant populations - with high-earning and lower-wage workers - tended to be those that prospered the most.
The analysis suggests, moreover, that the immigrants played a central role in the cycle of the economic growth of cities over the last two decades."
