Common questions

Not comparable per resident: this register licenses CONTRACTORS (businesses and qualifying individuals) rather than individual tradespeople, so this is a count of licensed businesses, not of workers. A per-resident rate and a state ranking are withheld here because they would compare businesses against other states' individual tradespeople.
