Pew Research Center, "Among the 50.7 million Hispanics in the United States, nearly two-thirds (65%), or 33 million, self-identify as being of Mexican origin." No other population comes close to this number.
When it comes to characteristics (2012), Ecuadorians have the highest median household income with $50k followed by Colombians with $49k. Dominicans come last with $36k. And as if anyone didn't know, Los Angeles, New York City and Miami are some of the top cities by Hispanic origin group. So what do all these numbers mean? Just that organizations may change their strategy locally and even nationally. "Let's target the Hispanic population in LA," or, "...the Puerto Rican population in Philadelphia," might be some of the comments you will here.
