Covid-19-related topics were mentioned a lot on social networks in 2021.

During the past two years, topics related to Covid-19 have been constantly mentioned in all media channels, including Facebook, which is one of the most prominent channels for information and social discussion in Vietnam. Discussion topics focused on disease symptoms, directives issued by the government on social distancing, and information about the largest vaccination campaign in history.

Besides the concern about the epidemic, the "home-centered" lifestyle that emerged during the time of lockdown led to an explosion in discussions related to the home experience.

Groups sharing stories about life at home attracted the attention of Facebook users in Vietnam, reaching the top 20 groups with the largest number of new members, such as Ở Nhà Vẫn Đẹp! (still pretty at home) and Ở nhà vui thấy bà! (happy at home). Established for more than 1 year, these two groups have had about 1.5 million members, 200-300 posts per day with thousands of interactions on each post.

Natural disasters and landslides

Vietnam is one of the countries heavily affected by natural disasters and climate change. In particular, post-flood landslides usually cause heavy damage. On Instagram and Facebook, discussions related to "landslides" increased dramatically in 2021, showing the community's great interest in natural and environmental problems.

In fact, climate change has long been one of the hot topics attracting public attention in Vietnam. According to the Meta Climate Change Survey and the Yale Program on Climate Change Communication, over 8 out of 10 people in Vietnam said they would like more information on climate change.

Nearly 9 out of 10 people said that they are “somewhat worried” or “very worried” about climate change. In particular, 67% of Vietnamese respondents believed that action to mitigate climate change will improve economic growth and create more jobs.

Cooking, culinary arts

In 2021, the trend of cooking and eating at home rose and generated a large amount of discussion related to food and cooking. Meta's statistics show that the top culinary keywords in Vietnam this year included "Bread", "Coconut", "Cinnamon" and "Flour".

Many Facebook groups related to cooking, baking or sharing recipes were formed, entering the top 50 most popular groups on Facebook and Instagram in Vietnam, with an increase of 500,000 new members on average this year. For example, Esheep Kitchen Family with more than 2.2 million members and tens of thousands of interactions per post, or Dạy Nấu Ăn Ngon and Học Nấu Ăn Ngon (teaching how to cook delicious cuisines and learning to cook delicious food) with nearly 1 million members each.

Interior design, architecture

Spending more time at home also facilitated interest in home decor and living space design, with discussions about interior design and architecture rising sharply year-over-year.

Through Facebook, many users shared photos and stories about living spaces, as well as their experience in decorating, design, and space renovation tips, thereby creating positive online communities. NGHIỆN NHÀ (home addict) is one of the prominent groups on Facebook, attracting 2.2 million members after over 1 year of establishment and more than 700,000 new members since the beginning of 2021.
