All 56 business types in St. Tammany Parish
Highest Groundwork market score first. Each score compares St. Tammany Parish with other counties for that business type, from 0 to 100. Spending per listing divides a whole spending line (all vehicle repairs, all eating out) by one type’s listings: the demand for each competitor, not a business’s revenue.
