In Atlanta, there's no obvious trend in attendance over the course of the year. Here are the last few months' numbers (average dancers at each dance, which is weekly):

April: 101

May: 80

June: 80

July: 121

August: 115

September: 109

October: 89

November: 94

I can't speak to the multi-year trend; I know Bill Porter has all that data accumulated.
