Vietnamese Gen Z consumers: what the 2026 data shows, and what it changes for a foreign brand

Almost every Vietnam entry deck has a slide on Gen Z. It usually says the same things: digital natives, mobile-first, value authenticity, care about sustainability, love short video. Most of that is true in a general way, and very little of it changes a decision. A launch budget is not allocated to “authenticity”.

The more useful questions are narrower. Which Gen Z: a student in Hanoi spending an allowance, or a 27-year-old in Ho Chi Minh City with her own salary? Measured by whom, in which cities, and when? And which of the findings would actually move money between lines of a launch plan?

This piece sets out what the recent survey data shows about young Vietnamese buyers, how far that data reaches, and the handful of findings that should change how a foreign brand plans its first year.

Who counts as Gen Z, and why the published numbers disagree

Gen Z is most often defined as people born between 1997 and 2012, which in 2026 means ages 14 to 29. Not every source uses that band. A widely cited 2015 report by Decision Lab and OMD counted 14.4 million Vietnamese “Gen Z” aged 13 to 21. Those people are now 24 to 32, and by the 1997 cut-off a good part of them are millennials. A Gen Z statistic is only as useful as the age band behind it, and older figures keep circulating long after the cohort they describe has moved on.

The second limit is coverage. The most recent consumer surveys with a usable age split, including the Q&Me studies cited below, were run online with respondents aged 20 to 49 in Ho Chi Minh City and Hanoi. They describe the older half of Gen Z, in two cities, with internet access. Teenagers and provincial buyers are largely absent.

For planning, it helps to split the cohort before reading any number about it. The three groups below are a working framework, not survey output:

A brand selling a premium serum is mostly selling to the third group. A snack brand is selling to all three, and the first one is the one the data barely sees.

What the 2026 surveys show about people in their twenties

Q&Me has published a run of short studies since August 2026, each based on 200 respondents aged 20 to 49 in Ho Chi Minh City and Hanoi. Several break results out for respondents in their twenties, which is the closest recent data comes to describing Gen Z buyers directly:

Two cautions before building on these. A sample of 200 split by age leaves a few dozen people in each age group, so a gap of a few points between groups may be noise. Gaps the size of the television figures, 9% against 35%, are not. And the respondents are online, urban adults; the figures describe that population and no other.

Read with those limits, the direction is consistent: people in their twenties lean harder on other buyers’ evidence, spend more time with video, and have largely left broadcast television.

Other buyers’ evidence decides more than the brand’s own claims

The review study is the one with the most direct consequences for a launch. Across all respondents:

• 74% need 50 or more reviews before they trust a product, and on average they avoid products rated below 3.6 stars.
• Photos or video in a review (69%) and detailed content (60%) matter more than the star rating (51%).
• 54% trust ordinary users’ reviews more than influencers’; only 13% lean toward influencers.
• Where people check depends on the category: Google Reviews and Maps lead for hotels and restaurants, TikTok and Facebook lead for cosmetics and fashion.

Put together with the 87% figure for people in their twenties, this describes a buyer who treats a new listing with eight reviews as unproven, however good the advertising that brought them there. For a foreign brand arriving with no local reviews at all, the first fifty on each hero product are not a nice-to-have. They are the point at which the paid traffic starts to convert.

That changes what the launch budget pays for. Sampling, follow-up messages after the first orders, and ordinary users posting honest video reviews belong in the plan as a line with a target and a date, not as a hope. Influencer content still has a job, mainly reach, but the same study suggests it does less to settle the decision than a crowd of ordinary buyers. How creator fees are structured, and what a brand is actually paying for, is covered in influencer marketing in Vietnam. Buying or inventing reviews is not an option: it is the fastest way to lose the trust the reviews were meant to build, and the review study found two-thirds of respondents confident they can spot fakes.

Short video holds the attention, and the platforms are splitting by age again

Decision Lab’s Connected Consumer report for the third quarter of 2025, published in November 2025, describes generational differences re-emerging after several quarters of convergence. TikTok keeps a strong hold on Gen Z for short-form content. Facebook still reaches broadly but has declined for two quarters and lost ground with younger audiences; among Gen Y, Zalo overtook it for the first time. YouTube leads for longer viewing across most age groups.

The Q&Me video study gives the overall reach: YouTube 92%, Facebook 82% and TikTok 74% of respondents, with traditional television at 21%.

For a launch plan, the consequence is not “move everything to TikTok”. It is that a Gen Z target and a household target are now reached in different places. A brand whose buyer is 24 but whose purchase is approved, or paid for, by a parent needs both, and needs to know which one it is buying with each line of the budget. A plan that buys Gen Z reach on Facebook alone will report healthy reach and underdeliver; a plan built only on TikTok can miss the person who signs off on the purchase.

AI is entering the comparison step

Decision Lab’s tracking for the third quarter of 2025 found Gen Z continuing to lead experimentation with AI tools, while older groups adopt them more selectively. Q&Me’s study of how urban Vietnamese use AI for shopping, published in October 2026 and based on AI users, gives a sense of what that does to buying:

• 62% research with AI always or often before buying; only 3% never do.
• ChatGPT (80%) and Gemini (68%) dominate.
• 17% name AI as their most-used product information source, behind only Google and Shopee or Lazada.
• Only 15% buy the AI’s pick as is; 60% check Shopee or Lazada first.
• Half say they discover more new brands through AI, and 35% now search on Google less.

Two consequences. First, a brand the AI tools know nothing about is absent from a comparison step a growing share of young buyers take. What those tools say is drawn from what is published: marketplace listings, reviews, press coverage, and the brand’s own pages in Vietnamese. Second, the marketplace listing still closes the decision. AI narrows the list; the listing, with its reviews and its price after vouchers, picks the winner. How the comparison on a page the brand does not control works is covered in how Vietnamese consumers find and compare brands.

Local brands, vouchers and the size of the basket

NIQ reported in October 2025 that eight in ten Gen Z consumers say they would support local brands, as part of a wider finding that buying more products made in Vietnam ranks among consumers’ top three ways to save money. The Q&Me country-of-origin survey reported in June 2026 points the same way: younger respondents were noticeably more confident in Vietnamese brands than older ones, and rated Chinese products markedly higher, with 23% of those in their twenties feeling positive about them against 5% of those in their forties.

What that does to the value of a foreign origin, and how to test whether origin still earns a premium in a specific category, is set out in do Vietnamese consumers trust foreign brands. The short version for Gen Z: “imported” is a weaker argument with this group than with their parents. A foreign brand competes with local brands on demonstration, on price after vouchers, and on relevance to how young Vietnamese actually live, not on where the factory is.

Price is the other half of the local advantage, and the part a foreign brand controls most directly. The most detailed Q&Me study devoted to Gen Z is older: fieldwork in November 2021, 379 respondents plus two focus groups. It found young Vietnamese to be frequent online shoppers who spend little per purchase, keen on promotions, and moving to cashless payment partly because of the promotions attached to it. Nearly five years on, the direction is consistent with the rest of the data, but the levels should not be quoted as current.

For planning, three implications hold up:

• Entry price points matter more than list price. A smaller pack or a trial size lets a buyer with a limited budget try the product, and produces the reviews the larger size needs.
• The price that counts is the one after vouchers. Young buyers compare the final price on the marketplace, not the recommended retail price. Setting a reference price every channel can hold is covered in pricing consumer goods in Vietnam.
• A brand that launches on deep discounts teaches this group to wait for them. The first sale campaign sets the price expectation for the next year.

A worked example: the same launch budget, read two ways

The figures below are invented to illustrate the arithmetic, not taken from any brand. A foreign skincare brand launches a serum aimed at buyers aged 20 to 29 in Ho Chi Minh City and Hanoi, with a launch budget of USD 60,000 for the first six weeks.

Plan A reads the audience as “digital natives on short video” and puts most of the money into reach. Plan B reads the review findings and funds proof first: enough sampling and follow-up to pass 50 reviews on each of three hero products before scaling reach.

In this invented case, Plan A buys two-thirds more traffic and sends it to listings most visitors still regard as unproven. Plan B buys less traffic and converts more than twice as much of it. The point is not the specific numbers, which will differ by category, but the order of spending. When most buyers want fifty reviews before they trust a product, reach sent to an empty listing is the expensive part of the launch.

Researching Gen Z in your own category

National surveys describe the terrain. They do not tell you how buyers aged 20 to 29 decide in your category, at your price point. A short programme can:

• Fix the age band in the brief. Write down which of the three groups you are selling to, and check that every figure you rely on was measured on that group.
• Read reviews by reviewer. On the three best-selling listings in the category, one local brand included, note which reviews come with photos or video, what they mention, and which questions recur. That is the evidence your own listing will need.
• Ask recent buyers, by group. Thirty short conversations, split across the age groups that matter, asking what they last bought in the category, where they checked it, and what nearly stopped them, will show whether reviews, creators, AI tools or price settled the decision.
• Ask an AI tool what it knows about your category. The answer shows which brands, listings and sources the comparison step currently draws on.

Online panels in Vietnam reach young urban buyers well and teenagers or provincial buyers poorly, so a category that depends on the latter needs a different method, scoped separately.

Where this work stops

MWY does not produce content, recruit creators or run campaigns, and takes no commission from any platform, agency, creator or research firm.

Establishing how buyers aged 20 to 29 decide in one category, which evidence settles the purchase, what price point holds after vouchers, and which local brands they compare you with, is the work of Vietnam Market Research: six weeks on one product line, ending in a written answer for headquarters. Primary fieldwork with teenagers or provincial buyers, where the category needs it, is quoted on its scope.
