Survivor: Millennials vs. Gen X is the 33rd season of the American CBS competitive reality television series Survivor. It featured two initial tribes of ten new castaways divided by generation: Gen X, born between 1963 and 1982, and Millennials, born between 1984 and 1997 (no one born in 1983 was cast this season).[1] It is the third season to divide the castaways into tribes by age. This season featured the first full cast evacuation, where all contestants were removed on the second day of competition due to Severe Tropical Cyclone Zena; the castaways were returned to their camps the next morning and no additional time was needed to complete the game.
