The tipping point is expected to come in 2055, when Asians will become the largest immigrant group at 36 percent, compared with Hispanics at 34 percent. White immigrants to America, 80 percent back in 1965, will hover somewhere between 18 and 20 percent with black immigrants in the 8 percent to 9 percent range, the study said.

Currently, 47 percent of immigrants living in the United States are Hispanic, but by 2065 that number will have dropped to 31 percent. Asians currently make up 26 percent of the immigrant population but in 50 years that percentage is expected to increase to 38 percent…

Part of the reason for the shift is that the fertility rate of women in Latin America and especially Mexico has decreased, said Mark Hugo Lopez, Pew’s director of Hispanic research. In Mexico, Lopez said, women are now having around two children, when back in the 1960s and 1970s, they were having about seven children per woman.
