Cohort comparison · -69-year gap
Silent Generation was born 1928–1945 and Generation Z 1997–2009, a gap of -69 years between the start of each cohort. In 2026 Silent Generation is aged 81–98 and Generation Z is aged 17–29. The clearest difference is that Silent Generation is defined by depression and war childhoods while Generation Z is defined by the first cohort to reach adolescence with a smartphone.
Born between 1928 and 1945 — children of the Depression and the Second World War, named by TIME magazine in 1951 for their perceived caution.
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.
