Public data. Explicit boundaries.
These reports measure industry activity and personal participation, not the number of listings in our directory. Employer locations, nonemployer businesses, and people are different units. We keep them separate, identify the reference year, and publish the evidence behind the analysis.
Our state comparisons show concentration, not a verdict on where to open a business. The fine arts school category includes dance alongside music, drama, and art instruction; it cannot support a dance-only national count.
Yoga practice includes independent practice as well as classes. Social dancing is not paid dance instruction. The calculator and quote examples use clearly labeled assumptions, not invented market averages. Each resource explains what its evidence cannot tell you.
