Want Educated Immigrants? Let In More Africans

The uproar over White House Chief of Staff John Kelly's comments about illegal immigration in an interview with National Public Radio last week still hasn't entirely died down. I haven't found the resulting discussion to be super-enlightening, so, as I did with an earlier Kelly comment about how nobody knows anybody in the military anymore, I decided to see if a few charts might clear things up.
 
So … let's dig into the data. More than 70 percent of undocumented immigrants in the U.S. are from Mexico and Central America, according to the Migration Policy Institute. Mexico is by far the most common country of origin, but the population of Mexican immigrants in the U.S. (both documented and undocumented) actually fell 6 percent from 2007 to 2015, according to the Pew Research Center, while the numbers of Salvadorans, Hondurans and Guatemalans in the U.S. continued to grow. So when we talk about illegal immigration into the U.S., we're mainly talking about immigration from those four countries, with El Salvador, Honduras and Guatemala playing a growing role and Mexico a huge but shrinking one. And yes, most of those who have come to the U.S. from these countries are probably of rural origin, although (1) there's not much good data on that and (2) there are indications that the rural share has been getting less “overwhelming” in recent years as Mexico and El Salvador, the two biggest sources of unauthorized immigrants in the U.S., have urbanized.
