The same measures for California and the whole U.S. Spending per listing divides a year of household spending on all food away from home by the sit-down restaurants counted, so it measures the demand for each competitor, not any business’s revenue.

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.
