According to the first-ever, state-by-state survey of American Millennials and Gen Z (ages 18 to 39), 63% do not know that 6 million Jews were exterminated by Nazis, and 36% thought the number was “two million or fewer.”
I'd like to see a more gradual break down of who doesn't know what. That range is uselessly large. I'd also like to know how the timelines match up with the rise in standardized testing.
edit: Found the study. At least I think I did. I didn't even see a mention of Gen Z. Just comparing Millennials and All Adults.
