2010–2024
Generation Alpha
Defined by Mark McCrindle, McCrindle Research — also called Gen Alpha. This boundary is contested rather than settled.
Not a Pew definition. Mark McCrindle chose the name while researching his book The ABC of XYZ (2009) and set the dates, 2010 to 2024: fifteen years, the span McCrindle gives the generations of today.
Where the edge is disputed
2010–2012. Pew puts 2010 to 2012 in Generation Z, which it runs to 2012. McCrindle, who named Generation Alpha, starts it in 2010 and puts these years in Alpha.
How old this cohort is now
Someone born on 1 January 2010, the earliest possible date in this range, is now 16. Someone born on 31 December 2024, the latest, is now 1. 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.
Every year in Generation Alpha
2010–2012 are filed under Generation Z on this site, following Pew Research Center; each of those years' own pages gives both.
