A single-vintage BPS benchmark is a snapshot of one year; the cross-year trend series is the trajectory across years. The 2018–2024 longitudinal data tracks how the agency universe's operating and structural characteristics moved through the bubble period and into the new-normal stabilization. This page covers the seven trend dimensions and the cyclical-vs-structural reading discipline.
What the series tracks.
| Trend dimension | What it reveals |
|---|---|
| Agency profile & structure | Size distribution, ownership, organizational shifts |
| Book quality & concentration | Retention and concentration trajectory |
| Specialization & regional | Line-mix and geographic distribution shifts |
| Producer demographics | Age, experience, succession-readiness trends |
| Producer productivity | Revenue-per-producer trajectory |
| Revenue composition | Commission/fee/contingency mix shifts |
| Revenue growth | Organic-growth-rate trajectory across the cycle |
Each dimension is a longitudinal series across the 2018, 2022, and 2024 vintages (with the companion years). Together they describe not just where the agency universe sits today, but how it got there — and which characteristics are trending in which direction.
The reading discipline.
A metric that spiked in 2021–2022 and reverted is cyclical — driven by the bubble. A metric that moved steadily across the full series is structural — and it will keep moving. The distinction determines how an analyst projects forward.
The core analytical discipline for trend data is separating cyclical from structural movement. Revenue-growth rates, for example, spiked in the 2020–2022 hard-market bubble and reverted in the new normal — a cyclical pattern. Producer-demographic aging, by contrast, moved steadily across the entire series — a structural trend that will continue regardless of the cycle. An analyst projecting an agency's forward trajectory must classify each metric correctly: extrapolating a cyclical spike overstates the forward case; ignoring a structural trend understates it.
The clearest structural story.
Of the seven dimensions, producer demographics tell the clearest structural story. The aging producer base — rising average age, lengthening tenure, and the thin pipeline of new producers — is a steady cross-vintage trend, not a cyclical artifact. It connects directly to the Silver Tsunami supply-side analysis: the producer-demographic trend is the agency-level manifestation of the same demographic wave that drives M&A supply. The trend series quantifies it across the benchmark cohort, complementing the whole-universe perpetuation data from Future One.
The BPS trend analysis pairs with the 2024 current vintage and 2022 vintage (the snapshots the trends connect), and the strategic context page (the year-specific narrative behind the trends).
