Longer life expectancies and changing demographics mean potential clashes between more generations in the workplace. Demographers typically segment the world population into six living generations: GI (born 1901—1926), mature/silents (born 1927—1945), baby boomers (born 1946—1964), generation X (born 1965—1980), generation Y/millennials (born 1981—2000), and generation Z (born after the middle to late 1990s).
