It’s hard to find current data – 2012 research released in 2015 seems to be about as close as we can get. The 2012 NEA States of Engagement report includes this bit of information – Baltimore is part of this, but the Washington, D.C. region probably biases the results a bit (still looking for more granular or current data, if you have any tips).
The percent of adults who attended a dance performance in 2012 in the Washington-Baltimore-Northern Virginia, DC-MD-VA-WV MSA (Metropolitan Statistical Area) was about 9.2% (range 7.0-12.0%).
If we use the lower-bound (7%), and apply that to the Baltimore region, dance attendance could be…
|Region||Total pop||Adult pop||Dance attendance|
Add this all up and it suggests a dance attendance population of about 150,000 people in and immediately around Baltimore.
