Highest Groundwork market score first. Each score compares Merrimack County 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. Compare it across markets with its index, where 100 is the U.S. figure for the same type; the real estate types, whose line is all housing costs, show the index only. How the score works.
