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. The score leaves out counties under 10,000 people, where a handful of businesses would swing it.
