Arizona is the denser market: 60.1 active licenses per 10k residents against 11.7 in Illinois. Density cuts both ways — more contractors to sell to per square mile, and more competition per job for the contractors themselves.

Household income runs higher in Illinois — $84,033 median against $76,830 in Arizona — which generally shows up in project budgets and ticket sizes.

Trade by trade

Counts are active licenses only, from each state's license board. A “—” means that board doesn't issue a statewide license for the trade, not that the trade doesn't exist there.
