Generation Alpha refers to the children born between 2010 and 2024. This generation is the largest in history, with almost 2 billion members globally. They are the first generation to be born entirely in the 21st century and the third millennium. Generation Alpha is defined as those born from 2010-2024. However, there is not yet a general consensus on the birth years of Generation Alpha, with some sources using starting birth years such as 2010, 2011, 2012, or 2013. The oldest members of Generation Alpha are currently 13 years old. Generational definitions are most useful when they span a set age range and thus allow meaningful comparisons across generations. That is why the generations today each span 15 years with Generation Y (Millennials) born from 1980 to 1994; Generation Z from 1995 to 2009 and Generation Alpha from 2010 to 2024.
