Go deeper in the Count Explorer
Everything above is an exact count for Optometrists on its own.

It arrives with Optometrists already selected, and it tells you on every answer whether the number is exact or an estimate.

Why a second filter changes the answer. The October 2026 cube holds one dimension at a time, so a count for Optometrists on its own is read straight out of it and is exact. Combine Optometrists 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.
