Understanding Generation Age Ranges in 2026
Generations are cohorts of people born within the same period who share the cultural, social, and economic events of their formative years. The boundaries between generations are drawn by demographic researchers; Pew’s definitions are the most widely cited, but there is no official standard.
The world population of 8,300,678,396 on 1 July 2026 is spread across eight generations, from the Greatest Generation (born before 1928) to Gen Beta (born 2025 onward). The largest generation worldwide is Gen Z with 2,047,968,142 people, 24.7% of the world. Worldwide there are 1,454,084,986 Gen X (17.5%) and 978,575,080 Baby Boomers (11.8%).
Generation definitions: Silent–Gen Z: Pew Research Center; Gen Alpha and Gen Beta: McCrindle Research. McCrindle’s own Gen Alpha span is 2010–2024 (2,008,524,902 people worldwide).
