From what age is Gen Z? Features and the difference from Millennials and Gen Alpha, explained in 5 minutes
"Gen Z" is drawing attention. They are not merely a youth segment; with their sheer population size and strong power to disseminate information, their influence on society and the economy is expanding rapidly. Using the internet and smartphones as a matter of course and sharing information instantly through social media, their behavior patterns generate a new form of consumption that conventional marketing methods can't fully capture.
Gen Z also naturally accepts values like diversity and sustainability, evaluating brands and products on axes such as "is it environmentally conscious?" and "is it tackling social issues?" At the same time, having lived through the Lehman shock and the pandemic, they also have a strong side that favors a realistic, level-headed lifestyle rather than ideals alone, holding a sense of balance that seeks both sustainability and value for money.
Correctly understanding these traits is a pressing challenge for companies and brands. Product development and marketing that ignore their values and consumption behavior not only fail to win empathy but also risk inviting a backlash through social media. Conversely, if you can offer services and products that align with Gen Z's sensibilities, it can lead to explosive word-of-mouth diffusion and stronger brand loyalty.
This article explains in detail, drawing on the latest insights: "What range does Gen Z actually refer to," "what features do they have," "how does a sustainable orientation appear in their consumption behavior," "where do the differences from other generations lie," and finally, "points for product development that resonates with Gen Z."

The age range and background of Gen Z
First, let's grasp the basics of "what ages does Gen Z specifically refer to?" To understand them, right in the thick of today's society, the era and environment they were born into are the key.
Age range
Gen Z generally refers to the generation born from the mid-1990s to the early 2010s, meaning ages 13 to about 29 as of 2025. In the position following the millennials, they're considered the first generation to have a digital-native sensibility.
Incidentally, the definition of Gen Z isn't strictly fixed. The USPew Researchsets it as "born 1997-2012," whileMcKinseysays "1995-2010," andJapanese surveyssay "1996 to the early 2010s" — the cutoffs differ slightly by research body and country. This is because the criterion for dividing generations is not "age" but the social and technological experiences shared in that era (the spread of the internet, the penetration of smartphones, and so on), which is why some ambiguity remains.
Growing up in an era of advancing penetration of digital technology, they're characterized as "the first generation of digital natives" .
Background and context
They grew up alongside the development of the internet, smartphones, and social media, making them the foundation of daily life.
They are also a generation for whom global social issues — climate change, social inequality, and so on — became familiar through education and information.
Having experienced economic anxiety — the Lehman shock and COVID-19 — in childhood and adolescence, they often hold a realistic perspective alongside their ideals.
In this way, Gen Z's identity has taken shape as a generation in which "affinity for technology," "interest in social issues," and "realistic judgment" coexist.

Features of Gen Z: the core of their values and behavior
To understand the principles behind Gen Z's behavior, let's explore the core of their values — what they prize, and what they dislike.
1. A digital-native sensibility
Having grown up with smartphones from childhood, their information gathering also centers on social media and video.
Communication online and instant judgment have become habitual.
2. Sensitivity to diversity and social issues
Through school education and social background, an awareness of "diversity," "equality," "sustainability," and the like tends to be naturally ingrained.
Empathy for the environment and social justice in particular is reflected in their lifestyle and consumption.
3. Emphasis on self-expression and empathy
They respect "being themselves," valuing self-expression on social media and empathy with brands.
Not the product alone, but "whether you can feel a story or philosophy you empathize with" becomes the deciding factor in support.
4. A stability orientation and realistic judgment
Influenced by global events, they tend to avoid unreasonable risk and favor steady saving and career design.

Gen Z's consumption behavior and sustainable orientation
In Gen Z's consumption behavior, there's a balance between "sustainable" and "practical benefit." Let's look at that reality more deeply and concretely.
1. An ethical / sustainable orientation
Many in Gen Z are interested in ethical consumption and sustainable choices, and they tend to strongly empathize with a company's philosophy and environmental consideration.
That said, there's a gap between interest and follow-through, and the reality that "they have the knowledge but it doesn't easily connect to everyday choices" is also pointed out.
2. Emphasis on value for money and time performance
Gen Z has a strong desire to use time and money efficiently, and value-for-money-focused consumption is pronounced.
In AMP's own survey of 400 Gen Z respondents, as criteria for choosing products, "price" was 51.3% and "functionality/practicality" 14.8%, while "sustainability" stayed at just 2.8%.
3. Purchase decisions based on real voices and empathy
Beyond social media posts and reviews, the opinions of friends and family are also important decision material.
"The voices of people who actually used it" and "content they themselves can accept" push purchases along.
4. An environment of information dissemination and reception
Because the "social messages" that brands and companies disseminate influence purchase behavior, transparent and honest communication on social media is called for.
In communication, being free of exaggeration, being specific, and including users' voices are elements that lead to trust.
5. Differences visible across generations
According to a Deloitte survey, Gen Z and baby boomers tend to have high interest in sustainability, while Gen X tends to be interested but slow to connect it to purchases.
There are even results showing that among younger men (late teens to early 20s) in particular, sustainable choices reach nearly half for clothing and cosmetics.

Comparison with other generations
To understand Gen Z's features better, comparison with other generations is effective. The table below summarizes data compared across several perspectives.

Surveying each generation's consumption tendencies, Gen Z shows marked interest in "diverse values," "empathy," "experience," and "sustainability," but in actual purchases, "price," "functionality," and "a sense of being convinced" are also important decision material.
Summary: perspectives for product development aimed at Gen Z
Gen Z is a generation that combines a digital-native sensibility, empathy for diversity and social issues, and judgment based on their "own axis." In their consumption behavior, a "sustainable orientation" and a "practical-benefit orientation" are intricately intertwined, and capturing that balance is the key to product development.
Points for product development aimed at Gen Z:
Build a story people empathize with
Clearly convey the sustainable background and social contribution, and design a story that gets shared naturally on social media.
Ensure value for money and convenience
Along with environmental consideration, build in "price," "function," and "convenience" as non-negotiable elements too.
Design that emphasizes personalization and experience
Offer experiential and customizable products/services that are easy to make one's own.
Communicate transparently and sincerely
Avoid exaggeration and communicate based on users' voices and concrete data. Beware of greenwashing.
Marketing that raises affinity with social media
Use influencers and real reviews. Strengthen your presence in the places Gen Z actually sees.
By combining these perspectives, you can design products that resonate with Gen Z's hearts and keep being chosen.
