Regarding children under 18 in the United States, how many participate

United States? How many participate in gymnastics and how many
gymnastic schools are in the U.S.?  How many participate in singing

There are dozens more dance studios in San Diego than there are acting
studios for people of any age.  Indeed, there are just a handful of
non-academic settings where one can learn the art of acting, yet there
are so many places people of all ages can learn to dance, in addition
to academic settings.  First, that says something about dance as the
people's art form, and second, it says something about the inequity of
the professional art form of dance, which is almost invisible compared
to the vast array of acting companies, profit and non-profit in San
Diego and elsewhere.  How is it that dance theatre, so widely embraced
in the tens of thousands of studios accross the country cannot compete
at the professional level with acting theatre?
