1981–1996
Millennials
Defined by Pew Research Center — also called Generation Y, Gen Y.
Pew fixed the end at 1996 in 2018, having previously left it open. Other definitions run to 2000, so someone born in the late 1990s is a Millennial on some tables and Gen Z on others.
Where the edge is disputed
1981. Pew's first Millennial year. Tables that start the Millennials in 1980 or 1982 disagree.
How old this cohort is now
Someone born on 1 January 1981, the earliest possible date in this range, is now 45. Someone born on 31 December 1996, the latest, is now 29. Both are worked out from today's date, the day this page was built — for an age that stays current, use the calculator on the relevant year's page.
