Epsilon expands adult age data coverage: Key updates for 2025

Adult age demographics are among the most critical components of a national consumer database, shaping how brands identify, target and engage with consumers—but they're not always easy to access. Gen Z adults and younger millennials move frequently, tend to have multiple email addresses, and are often experiencing multiple life stage changes at once, including entering the workforce, getting married or having children. Understanding what this critical group of buyers is interested in, and when, is an increasingly difficult challenge for marketers but it doesn't have to be.

Using Epsilon’s rich data sets, you can draw a comprehensive view based on demographic, psychographic and transactional insights. However, to achieve quality results, you need comprehensive data across all generations.

In 2024, Epsilon committed to a focused initiative: expanding our coverage of the 18- to 34-year-old demographic, a notoriously difficult-to-reach audience due to their evolving behaviors, shifting digital habits and selective brand loyalties.

On March 10, 2025, we delivered on this initiative by significantly expanding our National Consumer Database coverage within the 18- to 34-year-old segment, strengthening our ability to help brands effectively connect with young consumers as they advance through key life stages and purchase milestones.

This is an exciting addition to our National Consumer Database fulfilling on our long-term strategy to expand the view of the young adult audience,” says Warren Story, senior vice president of data solutions at Epsilon. “This is a key audience for brands who wish to engage loyalty early and often, to nurture and enrich consumer interactions as young adults advance through life stages with increased purchase power and influence.

Through innovative sourcing, we've increased young adult coverage by 23% on the National Consumer Database, providing brands with an important audience view that unlocks real consumer connections at the ground level within the emerging market.

Defining the future of person-first marketing

To effectively engage with customers and prospects, marketers need to understand what matters to each individual, communicate a message that reflects that understanding and learn more about them as a result of each interaction to inform their strategy.

Truly understanding a consumer allows marketers to develop relevant messages for that individual consumer. Recognizing that individual consumer in a channel allows the marketer to both deliver that message to the right person and tie what they learn from the interaction back to the same person.

With this product update, Epsilon delivers a more powerful solution for reaching and engaging the 18- to 34-year-old consumer—a segment that brands struggle to capture effectively.

Beyond overall value, this update allows for more precise audience targeting, expanded insights on young adult behaviors to enhance personalization and better alignment with evolving market trends in entertainment, finance and lifestyle categories.

We remain committed to ensuring Epsilon’s National Consumer Database evolves alongside market demands. As we move through 2025, we will continue refining core models and Market Trends to provide the most comprehensive and actionable consumer insights available.
