All 56 business types in Humboldt County

Counties under 10,000 people aren’t given a market score, since a few businesses can swing their figures. 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.

What is the Groundwork market score?

The Groundwork market score runs from 0 to 100 and compares a market with others of its kind for one business type: states with states, metro areas with metro areas, small-town markets and counties with their own. It weighs household spending per competitor (35%), households per business with payroll (25%), population growth (20%) and spending power (20%), each ranked against those peers. A higher score means that, taken together, the market has more household spending and more households for each business already there, faster population growth and more spending per household than similar markets. It describes a market, not any one site or deal. Markets with fewer than 5 map listings of the type, and counties under 10,000 people, aren’t scored, since a few businesses can swing their figures.
