Gen Z did it's job by voting for progressive Dem's, this group of 18 to 29 year olds having a 28 point swing to the Dems, give people what they want and they will reward you, they saved the day for the Dems as a whole
The break down by swing and age
This range also includes the youngest millenials. I am 29 years old (born 1993) and a millenial. My middle brother is almost 26 years old and at the cusp between the two generations (born 1996), and my youngest brother (born 2000) is almost 22 years old and Gen Z.
18-29 basically makes up 16% of the U.S population.
If the 30-44 group were split in half you'd probably see another large divide.
These bins (and "Generations") are somewhat arbitrary. Would be interesting to see the breakdown by birth year, given that.
