Go deeper in the Count Explorer
Everything above is an exact count for California on its own. To put California together with a second filter — a title level, a job function, a company size band, a revenue band — open it in the Count Explorer. It arrives with California already selected, and it tells you on every answer whether the number is exact or an estimate.

- California with a professional email address6,109,554
- California with all five fields present1,483,557
Why a second filter changes the answer. The August 2026 cube holds one dimension at a time, so a count for California on its own is read straight out of it and is exact. Combine California with a second dimension and the cube has no such cell — the explorer estimates it, shows the ceiling it cannot exceed, and labels it an estimate rather than passing it off as a measured number.
