AlphaBetaMinds

Generational research · October 2026

The generations that will
run the world.
We measure them.

Generation Alpha and Generation Beta are already more than a third of humanity, and Generation Z is the cohort now old enough to be asked about them — yet almost nobody has the numbers. AlphaBetaMinds is a live observatory: sourced statistics, long-form research and 850 free tools for the parents, teachers, marketers and researchers who have to understand all three.

Generation Alpha alive now
2,009,479,379

Born 2010–2024. The cohort is closed — it only changes through mortality.

Generation Beta alive now
238,273,118

Born 2025–2039. Every birth on Earth right now joins this cohort.

≈ 4.2 births per second worldwide, all of them Generation Beta.

The short answer

Generation Alpha (born 2010–2024) numbers about 2.01 billion people and Generation Beta (born 2025–2039) about 238.3 million and growing by roughly 4.2 births every second. Together they are already more than a third of humanity.

1997 — 2009 · CLOSED COHORT

Generation Z

The oldest cohort young enough to have no memory of a world before the internet, and the only one of the three old enough to answer questions about itself.

  • Aged 17–29 in 2026
  • Thirteen birth years — the narrowest of the three cohorts
  • The oldest were 10 when the iPhone shipped; the youngest were unborn
  • Mostly the children of Generation X, not of Millennials
2010 — 2024 · CLOSED COHORT

Generation Alpha

The first generation born entirely in the 21st century, and the first raised by tablets, algorithmic feeds and voice assistants from birth.

  • ≈ 2.01 billion alive today
  • Aged 2–16 in 2026
  • Oldest members finish secondary school from 2028
  • Peak workforce years: 2035–2060
2025 — 2039 · OPEN COHORT

Generation Beta

The first generation for whom AI is not a product but the weather. Projected to reach 2.1 billion people and 16% of the world by 2035.

  • ≈ 238.3 million alive today and rising every second
  • Aged 0–1 in 2026
  • First Betas start primary school in 2030
  • Will be 11–25 years old in 2050

Why this matters now

Plenty has been written about Millennials and Gen Z, and almost none of it settles the simplest questions — which birth years count, and where one cohort ends. The people who have to make decisions about Alpha and Beta — a teacher planning a curriculum, a parent setting a screen-time rule, a brand deciding whether Roblox is a channel — are working from anecdotes.

We build the missing layer: numbers with sources, tools that do the maths, and plain-English answers a search engine or an AI assistant can quote.
