Small and medium businesses account for the majority of consumer spending in large cities, but there is a wide range across cities. In New York consumers made the highest share of local commerce purchases at small and medium enterprises in 2015 Q2, as much as 75 percent of all spending. This share was twenty percentage points higher than the share in Columbus, where local commerce spending at small and medium enterprises was just over 54 percent of total spending. And larger metropolitan areas typically have a greater share of spending at small and medium enterprises than smaller metro areas.
But the metro area shares above mask an important point. If we break the metropolitan areas down into the central city and the surrounding areas, as our PLCC data allow us to do, we find that central cities uniformly have more spending at small and medium enterprises than do their surrounding metropolitan areas.
