It's net movement, not gross. There's raw data that shows all 53 x 53 of how those born in the 50 states, District of Columbia, Puerto Rico, and overseas live in the 50 states + DC + PR + non-US. I can't do the analysis easily from my phone, but you can break it out to what percentage of Americans live in a different state of birth. There's probably raw data that can show the Gen Z specific stats, too.
