Who Gen Z is

Researchers and marketers typically place Gen Z’s birth years somewhere between the late 1990s and early 2010s, though the exact boundaries vary by source and no single definition is universally agreed. What distinguishes the cohort is context, not birth certificate: they came of age after broadband became widespread, with smartphones present through adolescence and social media woven into school social life from the start. The youngest members of the generation were still teenagers as of 2026 while the oldest were approaching their late twenties and entering the workforce in significant numbers.

How Gen Z shapes social media

Gen Z is widely credited with accelerating the dominance of short-form video, popularising vertical formats, and developing much of the slang — "rizz," "NPC," "chronically online" — now found across every demographic online. They tend to prefer authenticity and lo-fi content over high-production brand work, and many researchers note higher scepticism toward traditional advertising than older cohorts. Platforms like TikTok and BeReal found early traction among Gen Z users before expanding to broader audiences.

What Gen-Z fluency means for brands

Attempting to speak "Gen Z" as a performative layer without genuine understanding tends to backfire visibly — the audience is quick to identify and mock inauthenticity. Brands that build real credibility with the cohort typically do it by showing up consistently, responding genuinely in comments, and earning cultural relevance rather than claiming it. Understanding the slang and platform norms is a starting point, not a substitute for an honest voice.
