Cohort comparison · -13-year gap
Generation Z was born 1997–2009 and Generation Alpha 2010–2024, a gap of -13 years between the start of each cohort. In 2026 Generation Z is aged 17–29 and Generation Alpha is aged 2–16. The clearest difference is that Generation Z is defined by the first cohort to reach adolescence with a smartphone while Generation Alpha is defined by the first generation born entirely in the 21st century.
Born 1997–2009 on the boundaries used here, Gen Z is the last cohort with any memory of a pre-smartphone world and the first to reach adolescence on social media.
The cohort born between 2010 and 2024 — the first born entirely in the 21st century, and the first raised with touchscreens and algorithmic feeds from infancy.

Generation Z covers births from 1997 to 2009 and Generation Alpha from 2010 to 2024. The first cohort to reach adolescence with a smartphone defines the first; The first generation born entirely in the 21st century defines the second.
In 2026, Generation Z is 17–29 and Generation Alpha is 2–16.
Generation Z is ~2.0bn and Generation Alpha is ~2.0bn.
There is no boundary between these two directly unless they are adjacent cohorts. Boundaries are conventions set by McCrindle Research, not official definitions, and other frameworks draw them a year or two apart.
