I thought this was an interesting statement as well:
Generation Z is diverse. They are only 55 percent white and will be the last majority-white generation in America.
That's not necessarily true. IF current trends continue, that is the case. But current trends are not necessarily permanent.
Sort of along the lines of statistics about children killed by guns, in which "children" may include those up to age 16 ... or 18 ... or 21 ... or even 26, depending on whose statistics you use, much depends on how "white" and "non-white" are defined. Just as one example, the BATFE Form 4473 for buying firearm through an FFL dealer, has a question for "Ethnicity" (Latino/Hispanic, or not Latino/Hispanic), and another question for Race (American Indian or Alaska Native; Asian; Black or African American; Native Hawaiian or other Pacific Islander; and White). So what box do Arabs check? By many systems, Arabs are not considered to be whites. And note that under Race there isn't anything for Hispanic. Many, perhaps most, Hispanics around the world are white, but in claiming that Generation Z is the last majority white generation in the U.S. I'm sure the claim considers all Hispanics as non-white.
And that's a notion that would have incensed my late wife, who was a Latina. In fact, she resented being classified as 'Hispanic." Her view was that she wasn't born in Spain, she had never traveled to Spain, so how could she be "Hispanic"?
