What's here
The colour and the shape tell you what you are looking at before you read a word.
Generation Alpha (born 2010–2024) numbers about 2.01 billion people and Generation Beta (born 2025–2039) about 241.7 million and growing by roughly 4.2 births every second. Together they are already more than a third of humanity.
Born 2010–2024. The cohort is closed — it only changes through mortality.
Born 2025–2039. Every birth on Earth right now joins this cohort.
≈ 4.2 births per second worldwide, all of them Generation Beta.
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.
The first generation born entirely in the 21st century, and the first raised by tablets, algorithmic feeds and voice assistants from birth.
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.

Where they are
Eight countries hold 50% of the Alphas in our 194-country dataset. Each profile carries a live birth counter running at that country's own rate, plus the fertility, schooling and connectivity numbers behind it.

Timeline
The iPad launches the same year. The first Alphas are born into a touchscreen world.
A billion Alpha children move to screen-based learning almost overnight.
The first Betas are born into homes where generative AI is already ambient.
The first Alpha cohort reaches university and the labour market.
AI tutors are standard classroom infrastructure, not a pilot.
Generation Beta becomes the single largest child cohort in history.
The cohort tops out near 2.1 billion people.
Alphas are 26–40 — peak earning, peak influence. Betas are 11–25.
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.
The brief
New Gen Alpha and Gen Beta data, one chart, one tool, no filler. Unsubscribe in one click.
We never sell or share your address. See our privacy policy.
Generation Alpha covers births from 2010 to 2024 inclusive. The boundary comes from demographer Mark McCrindle, who named the cohort and moved to the Greek alphabet after Generation Z.
Generation Beta covers births from 2025 to 2039 inclusive. The first Betas were born on 1 January 2025.
About 2.01 billion Alphas and 241.7 million Betas are alive right now — roughly 27.2% of humanity combined. Our live counter updates every second.
Parents, teachers, marketers, product teams, journalists and researchers who need defensible numbers about the two youngest generations, not opinion pieces.
