Bilibili Demographics: Who Are These Gen Z Users?

Why Bilibili Demographics Matter 📊

We've been running paid media on Bilibili since 2023. Most international agencies we talk to still treat it as "that anime platform" or "Chinese YouTube for kids." Both are wrong.

Bilibili's 366 million monthly active users represent something unique in China's digital landscape: a concentrated, high-engagement audience of young consumers who actually watch ads (when done right). The demographic profile is so distinct that we created this guide to help our clients understand whether their budget belongs here.

This isn't about vanity metrics. It's about whether your target audience spends time on Bilibili—and whether they have the purchasing power to justify your ad spend.

Age Distribution: Young and Getting Younger 🎯

Here's the headline: Bilibili users are young. Really young. The average age is 26, but that masks an important trend—new users joining in 2025-2026 average 22 years old.

What does this mean? If you're targeting consumers aged 18-35, Bilibili gives you access to China's most concentrated young audience. But—and this is critical—you need to understand their content consumption habits. They don't watch 15-second skits; they watch 20-minute deep dives.

Gender Split: The Rare 1:1 Balance ⚧️

Most social platforms in China skew heavily male (Baidu, Zhihu) or female (Xiaohongshu). Bilibili is the rare platform with a nearly perfect 1:1 gender ratio.

Why does this matter? Because it means you can run a single campaign without dramatically different creative for each gender. Compare this to Xiaohongshu (80%+ female) where beauty and lifestyle ads dominate, or Zhihu (65%+ male) where tech and professional content rules.

In our experience, Bilibili's gender balance makes it ideal for:

• Consumer electronics – Both genders research before buying
• Automotive – Young couples making first car decisions
• Food & beverage – Shared lifestyle interests
• Gaming – Still male-dominated, but female gaming audience is growing fast

Geographic Concentration: Tier 1-3 Cities 🌏

Bilibili users aren't scattered evenly across China. They're concentrated in cities with disposable income.

If your brand targets tier 1-3 consumers (and most international brands do), Bilibili's user base aligns well. The platform penetration in lower-tier cities is growing, but the core remains urban.

Engagement Metrics: The 107-Minute Habit ⏱️

Here's where Bilibili differs most from short-video platforms. Users don't just scroll; they watch. The average daily time spent is 107 minutes—higher than Douyin for this demographic.

More importantly, 80%+ of top 100 videos by play volume are medium-to-long format (10+ minutes). This isn't TikTok-style consumption. It's closer to YouTube, but with a more engaged community.

For advertisers, this means:

• Longer ad formats work – Mid-roll placements in 15-minute videos perform better than you'd expect
• Deeper storytelling is possible – You have 60 seconds; use them to tell a story, not just show a logo
• Comment sections matter – Bilibili users read and write comments more than any other Chinese platform

Paying Users: Quality Over Quantity 💳

Bilibili users don't just watch—they spend. The platform has 35.66 million monthly paying users (for premium memberships, content, games).

But the more interesting metric is willingness to pay for non-entertainment products. In our campaigns:

• Consumer electronics: 3.2% click-to-purchase rate (higher than Baidu search for same products)
• Fashion/apparel: 2.1% conversion rate when creative feels authentic (not "ad-like")
• Food & beverage: 4.5% CTR on product placement videos vs. standard pre-roll

The common thread? Bilibili users respond to content that doesn't look like an ad. The platform's community is sensitive to inauthentic promotion—but rewards brands that create genuine value.

Retention: The Loyalty Metric That Matters 📈

Bilibili's retention numbers are genuinely impressive. These aren't vanity metrics—they indicate a platform users return to daily.

Compare this to short-video platforms where users might spend more total time but are more likely to drift between apps. Bilibili users have made it part of their routine.

For advertisers, high retention means:

• Frequency capping matters – Users will see your ad multiple times; make sure the creative doesn't annoy
• Community features drive brand recall – Ads that spark discussion in comments outperform silent ads
• Long-term campaigns work better – Bilibili isn't a one-hit platform; sustained presence builds familiarity

What This Means for Advertisers 🎯

Let's translate these demographics into practical advertising decisions.

Bilibili Is Right for You If...

• Your target audience is aged 18-35
• You're in consumer electronics, automotive, fashion, gaming, or F&B
• You have creative that can tell a story (not just showcase a product)
• You're willing to engage with comments and community (not just broadcast)
• You want to build brand equity, not just drive immediate sales

Bilibili Probably Isn't Right If...

• You're targeting seniors (55+) or very young children
• Your product requires immediate, hard-sell conversion (use Baidu instead)
• You don't have resources to create platform-native content
• You're unwilling to engage with negative comments (they will happen)

The Bottom Line 🪣

Bilibili's demographics tell a clear story: this is China's platform for reaching young, urban, engaged consumers who value content depth over quick entertainment. The 1:1 gender balance, concentration in tier 1-3 cities, and extraordinary retention rates make it a unique advertising channel.

But—and this is important—Bilibili isn't a platform where you can repurpose creative from elsewhere. The audience demands authenticity. They'll engage deeply with content that respects their intelligence, and ignore (or actively dislike) content that feels like a generic ad.

We've seen both outcomes. The difference usually comes down to whether the brand treated Bilibili as a distribution channel or a community.
