It's not 42% of the general population. It's 42% of iPhone users, and if informal survey means this was an online survey the results are nearly worthless due to self-selection.

“A survey of 11,000 U.S. adults by Bloomberg News and Morning Consult shows the [Gen Z] generation is more willing than its predecessor to put its money where its values are.”
“They were born after the internet went mainstream; the oldest were about 10 when the iPhone was introduced. “We are the social-media natives.””
““There’s this misconception that we’re scrolling mindlessly.” What Gen Z’s actually doing is connecting and communicating and figuring things out—like where [and how!] to spend their money.”
