Overall, Pinterest’s ad audience in South Korea can be described as young-adult oriented, with its strongest concentration in the 18–34 population and especially in the 25-34 group.
Gender structure
The gender split in South Korea’s Pinterest Ad Account data is clearly weighted toward female users. The Female audience totals 2,483,000 users, which is about 68.1% of the total estimated audience.
For comparison, the Male audience totals 885,000 users, or about 24.3%, while Not Set accounts for 279,000 users, or about 7.7%.
Female users still form the clear majority in South Korea, but the Not Set category is also relatively large here compared with several other countries in this batch. That makes the overall gender structure slightly more mixed than markets where nearly all users are concentrated in the Female and Male categories alone.
The largest female segment appears in 25-34 (963,000). This alignment with the platform’s strongest age bands suggests that Pinterest’s scale in South Korea is driven primarily by women, especially in younger adult cohorts.
The Not Set category as a distinct segment
The Not Set category totals 279,000 users in South Korea. This is not a marginal number and should not be ignored when interpreting the demographic structure of Pinterest’s estimated ad audience.

While most of the audience is still concentrated in the Female and Male categories, Not Set remains a visible third segment. In a market of this size, that category is large enough to matter in campaign planning, reporting, and any analysis that relies on gender-based audience splits.
