Washington is the denser market: 84.0 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 Washington — $95,237 median against $84,033 in Illinois — 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.
