"In any given year, how many people visit the world's planetaria?"
This simple question is an important one, as it reflects upon the very viability and importance of our profession, and the dome theater itself as a media outlet and dispenser of enlightenment — astronomical and otherwise.
Since 1990, I've collected annual attendance figures for planetaria in the Loch Ness Productions database. School shows, public shows, concerts, laser shows, whatever and altogether — how many humans experience the simulated environment of the starry sky under a planetarium dome?
While I've received responses from about 10% of the world's theaters, this tally uses only attendance reports received over the last five years to keep the projection relatively current. For some additional observations and disclaimers, read this page.
A quick explanation about my methods:
Here's the tally:
As always, I ask your assistance in providing numbers: a recent attendance figure over a 12-month period for each of the domes your institution operates. I'll incorporate the information and publish it periodically here, just as I now have.
The best way to respond is to fill out an LNP Dome Theater Compendium Update Form — as this will allow us to "freshen" the data we have about your theater facilities, and fill in any blank fields.
And if you have already responded, thanks!
