Gen Z Population: How Many Gen Zers Are There in the U.S. and Globally?

Ever wonder about the global gen z population? There are roughly 2 billion Gen Zers on the planet — about 26% of every human alive right now. In the U.S. alone, that number sits at approximately 71 million, making Zoomers one of the two dominant generations reshaping almost everything about how money moves, who wins elections, and what culture actually looks like.

What Years Are Considered Gen Z?

The most widely used definition, backed by the Pew Research Center, puts Gen Z as anyone born between 1997 and 2012. The Gen Z age range in 2025 spans 13 to 28 — from middle schoolers to people with mortgages and actual careers.

There’s no official body that hands down these dates. Different researchers draw the lines slightly differently. Some start Gen Z at 1995. Others end it at 2010. But 1997–2012 is the range you’ll see cited most consistently across academic and market research, and it’s the one the U.S. Census Bureau works from.

The oldest Gen Zers graduated into a post-2008 recession economy. The youngest were in elementary school during COVID. That 15-year window contains wildly different lived experiences — which is part of why the generation is so politically and culturally split.

How Many Gen Zers Are in the US?

This is the number most people get wrong — or just approximate badly. According to U.S. Census Bureau data, Gen Z has over 71 million people in the U.S., representing 21% of Americans. Visual Capitalist That makes them the second-largest generation domestically, just behind Millennials at roughly 74 million.

The Gen Z percentage of population in the U.S. clocks in at around 20.81%, per Statista’s breakdown of Census Bureau figures. Globally, that share jumps to 26% — roughly 2 billion people, according to NIQ and World Data Lab. CTAM The reason the global number looks so much larger is demographic weight in South Asia, Southeast Asia, and sub-Saharan Africa, where younger populations dominate the age pyramid.

In the U.S., Gen Z is approximately 48% non-white — the most racially and ethnically diverse generation the country has ever produced. Market In the West specifically, Hispanic Gen Zers match non-Hispanic white Gen Zers at 40% each. That’s not a footnote. That’s a structural shift.

How Does Gen Z Compare to Other Generations in Size?

Here’s where the common narrative gets sloppy. Gen Z is constantly called the largest generation in history — and globally, that’s arguably true. But inside the U.S., it’s not. Millennials are the largest American generation at roughly 74 million, with Gen Z second at over 71 million. Baby Boomers and Gen X each sit around 64–65 million. Visual Capitalist

So the “Gen Z is the biggest” claim is technically a global stat that most articles apply to the U.S. without flagging the difference. Worth knowing if you’re citing this for anything serious.

Why Does the Gen Z Population Size Matter?

Because size plus timing is a specific kind of power. Gen Z workforce statistics are where this becomes concrete. By 2025, Gen Z is projected to make up about 27% of the global workforce Analyzify — and they’re entering peak earning and spending years at the same time. Gen Z controls roughly $450 billion in spending power globally, with NIQ projecting that figure could reach $12 trillion by 2030. Electro IQ

Politically, the math is landing too. Gen Z made up an estimated 17% of the eligible U.S. electorate in 2024, and that share grows every election cycle. The generation isn’t monolithic either — Pew data consistently shows a political split between older Zoomers who lean left and younger ones who came of age during COVID and lean noticeably more conservative.

Here’s the take nobody says plainly: Gen Z is the last U.S. generation born into a majority white country. The Census Bureau confirmed that as of the 2020 census, non-Hispanic white Americans fell below 60% of the total population for the first time. Gen Z, born 1997–2012, arrived right at that inflection point. Every cultural and political fight playing out right now — about identity, representation, who gets hired, what gets taught — is downstream of that demographic reality. The generation’s size is almost secondary to what that size looks like.

The Numbers Tell You Where the Power Is Going

71 million Gen Zers in the U.S. is a big number. But the number alone doesn’t move anything. What moves things is that this generation is simultaneously entering peak earning years, peak voting years, and peak cultural influence — all at once, faster than any generation before it. NIQ projects that when Gen Zers reach 25, their mean spending per capita will outpace prior generations, and by 2030, Gen Z will contribute more wealthy individuals to every region in the world. CTAM That’s not a trend. That’s a transfer.
