The biggest generation the world has ever seen is not the Baby Boomers or the Millennials. It is the one growing up right now: Generation Alpha.
Who counts as Gen Alpha?
Gen Alpha is made up of children born from 2010 to 2024, according to McCrindle Research, the Australian research firm that coined the term. They are mostly the children of Millennials and the younger siblings of Gen Z.
Almost 2 billion of them
Here is the headline number. McCrindle Research reports that more than 2.8 million Gen Alphas are born every week around the world. With the last members of the generation born in 2024, the cohort will number almost 2 billion by 2025 — the largest generation in the history of the world. In an interview with IMD, researcher Mark McCrindle confirms the scale: around 2 billion Alphas alive by 2025, surpassing every previous generation, and the largest cohort the world is ever likely to see, since global population growth is expected to slow.
Why size matters
Size brings influence. Alphas are already shaping popular culture, social media, and the products brands design for them. The same IMD piece notes that by as early as 2030, Alphas could account for 11% of the global workforce. Their biggest concentrations are in India, China, and Nigeria, but the generation is growing fast in every country.
For parents, the takeaway is simple. Gen Alpha is not just big — it is the biggest generation there has ever been. The schools, toys, and technology of the future will be built around a group of almost 2 billion people. Understanding what makes them tick is not a niche hobby. It is homework for the whole decade.
