Throughout America, the number of participants in choirs has increased where more than 42.6 million individuals (both adults and children combined) are now considered to be part of some choral group.
There are more than 270,000 choral groups all across America (in 2009, as per the study). This participation is far more than any other performing arts.
1 in 6 Americans (above 18) sings in a chorus.
In 2009, the percentage has increased from 14% to 17%.
