Self-Employed is an IAB Audience Taxonomy 1.1 cohort, indexed under Unique ID 45 in the Demographic branch of the taxonomy. Over the most recent 30-day observation window, the Trillboards DOOH network logged 0 cohort observations tagged with this segment across 0 approved screens. Each observation is an aggregate cohort tag emitted by the on-device computer-vision pipeline plus the cloud Gemini call that backs Trillboards' Federated Edge Intelligence Network (FEIN); the underlying data is grouped per-screen-per-window and surfaces here as a network-wide count, never a per-device identifier or per-person attribute. The cohort sits inside the Demographic → Education & Occupation → Employment Status hierarchy, which is what most demand-side platforms consume when they buy "Self-Employed" inventory off the open exchange.
For buyers running programmatic DOOH campaigns against Self-Employed, the segment surfaces most often in venue categories — the three highest-screen-count surfaces in the Trillboards network where the audience appears in measurable volume. Grocery carries 0 approved screens at an average floor of — CPM, while Convenience and Retail round out the top three. Daily impressions per screen vary by venue: high-foot-traffic surfaces (grocery, convenience, transit-adjacent retail) hit four-digit dailies, while quieter dwell-time surfaces (offices, waiting rooms) sit lower but command stronger attention scores. The Trillboards audience pipeline blends edge-inferred face counts and gaze seconds with cloud-inferred segment tags, so the 45 cohort signal you see in your DSP is anchored to actual on-screen attention — not a panel extrapolation.
Ad-fit considerations for Self-Employed: because IAB AT 1.1 segments are designed for cross-publisher portability, buyers can map their existing audience strategy directly onto Trillboards inventory without rewriting taxonomy. The demographic root of the cohort suggests creatives should respect any frequency-cap and brand-safety overlays the demographic implies, especially when paired with adjacent segments. Pair this segment with a venue filter (top-3 above) and a daypart restriction to push effective CPM lower while holding completion rate. 0 observations in 30 days places this segment in long-tail territory — best used as a refinement layer on top of broader cohorts on the Trillboards network. As with every Trillboards data product, the surface is k-anonymized and exposed at the cohort level only; per-person attributes are never extractable from this index.
Hierarchy context: this segment is a descendant of Demographic → Education & Occupation → the Employment Status tier. Buyers using broader cohorts (one or two tiers up) capture a larger share of the network at the cost of segment specificity; buyers using this leaf node trade reach for precision. The Trillboards segment fanout in the SSP-side OpenRTB payload emits every level of the tier chain, so a single bid can target this leaf or any ancestor without resending the request — partners read the IAB segtax=4 code and apply the standard IAB Audience Taxonomy dictionary at their end.
