African Immigration and the United States
There is now a significant African-born population in the United States– about four percent of 38.5 million immigrants. It is newer, younger, and better educated but also poorer than other immigrant groups, as Kristen McCabe from the Migration Policy Institute notes in her fascinating article “U.S. in Focus: African Immigrants in the U.S.” (It should be noted that her statistics include North Africa and she does not discuss undocumented aliens.) It seems likely to me that their relative poverty reflects their recent arrival; other immigrants include significant numbers who have established themselves in the United States for a long time.
