The three most popular social media platforms globally for all ages, based on monthly active users and overall reach in 2025, are:
- YouTube
- The most widely used social media platform with approximately 3.9 billion monthly active users, reaching about 47.5% of the world's population
* It is a video-sharing platform used by a broad demographic worldwide, except in countries where it is banned (e.g., China, Iran, Russia)
- Facebook (Meta)
- The second most popular platform with around 2.1 billion monthly active users globally
* Facebook has a broad user base across all age groups and remains a dominant social network worldwide
- WhatsApp (Meta)
- A leading messaging app with over 2 billion users, widely used for communication across all ages globally
* Its end-to-end encryption and multimedia sharing features make it popular for personal and group communication
Other platforms like Instagram and TikTok are also extremely popular, especially among younger users, but their user bases are smaller compared to these top three when considering all age groups worldwide
