The U.S. workforce is now composed of four generations: Baby Boomers, Gen X, Millennials, and Gen Z. Age ranges for these generations in 2019 were: boomers (55-73); Gen X (39-54); Millennials (23-38); and Gen Z (6-22).
More than one in three U.S. workers are now Millennials, having surpassed Baby Boomers and Gen Xers as the largest generation in the U.S. labor force. Born between 1980 and 2000, they are also the first truly digital generation.
The Millennial generation has been pouring into the workforce since the late 1990s and increasingly they're being promoted to supervisory and management positions.
