Birth years used by this Lab
A working definition, not an official Census category.
Generation boundaries are conventions
Who is Gen Alpha?
There is no official Census category called Gen Alpha. This Lab uses 2010–2024 as a working definition so age-based population data can be read honestly — and so it is clear exactly where each measure stops.

Approximate ages in 2026
The exact age depends on birthday and where a boundary is drawn.

Census state dataRace alone
Six mutually exclusive race-alone categories that add to 100% after rounding.
Hispanic origin
Reported separately from race — these figures do not form another 100% split.
Keep race and Hispanic origin separate when presenting this portrait.
Global
The world’s youth population is larger — and unevenly distributed.

people ages 0–14 worldwide in 2024Insight
The youth majority is already outside North America.
North America is only 3.2% of the world’s ages 0–14 population. The next wave of youth culture is being shaped in many countries and languages at once — already visible in KPop Demon Hunters and K-pop, in IShowSpeed’s global soccer streams, and in teenagers like Lamine Yamal becoming worldwide references before they leave their teens.
From who they are to how they live.
Demographics establish the population. The rest of the Lab handles behavior, culture, comparison, and evidence.
