Trouble signs
Competition
No company runs more than one place of business here, an independent market.
New and established
A young market: many recent start-ups, dynamic, but less proven.
Moving in and out
A move is a place of business closing and the same company opening one in another area within 90 days. Chains are left out. A business that moves and keeps its place-of-business number isn't counted here yet, so the real number of moves is higher.
