Sources & Methodology

We cite a lot of numbers. Here's where each one comes from — and where we've done our own math, we say so.

Verified Sources

These figures come from named, published research. We use the exact attribution each source publishes.

Location Page Population Data

Population figures for California markets come from the California Department of Finance's E-2 County Population Estimates (July 2025). Arizona and Nevada figures come from the U.S. Census Bureau's 2024 American Community Survey. These are different data products with different methodologies and release dates, so figures are not strictly comparable across state lines. We use each state's most authoritative current source rather than a single national dataset.

Youth sports participants and community reach figures on every location page are calculated from that page's population using the same chain: population × 15% (ages 6–17 share) × 58% (organized sports participation, Project Play / National Survey of Children's Health) = participants; participants × 3.0 (household factor) = community reach.


Every Other Statistic on the Site

Some of these carry a citation we haven't independently verified. Some carry no citation at all, because we removed an attribution that didn't hold up and haven't replaced it with a guess. Both are marked below.

"Unverified" means the citation is what the page currently shows, but we haven't independently confirmed it. "Pending review" means we've flagged it and are waiting on a decision before changing it further. Neither is invented — both are exactly what's on the page today. Two claims that had no real source — 89% brand preference and $54 billion in global sponsorship spending — have been removed from the site entirely rather than left up with a note.


What We Calculate Ourselves

Some figures on this site are our own estimates, not published research. Our market reach figures are built from published population data and participation rates, multiplied by a household factor — the methodology is shown on each page where it appears. Sponsorship valuations from our calculator are estimates based on your inputs, not guarantees.

In the calculator specifically: the Fair Market Value "Base Rate" per asset and the location/business-density multipliers are Zubie Five estimates, informed by published ranges but not individually sourced — labeled as such directly on the calculator. Channel CPM benchmarks are blended industry estimates (IAB, OAAA, IEG), also labeled on the page. The old "ad blindness" comparison in our traditional-vs-community tool has been replaced with attention-likelihood figures from Priority Partnerships / YouGov Sport, 2026 — a real, cited study, not an internal estimate.

We don't publish modeled impression counts or projected returns. Our end-of-season sponsor reports use counted attendance, counted event dates, and dated photographs — nothing multiplied.
