This section provides data on banking market competition in terms of deposits of commercial and savings banks operating in New England. Market shares are provided for New England as a whole, for each state, and for the local banking markets as defined by the Federal Reserve Bank of Boston. A geographical description of each market is provided along with a list of branches of each bank operating in the market and the amount of deposits in the branches. This information can be useful for antitrust analysis, namely assessing an effect on competition of potential bank mergers and acquisitions.

Note on RMA:
Current banking market definitions are based on 2000 RMAs. Only certain banking market definitions include RMAs. A Ranally Metro Area (RMA) represents the developed areas around each major U.S. city, as defined by Rand McNally & Co., a geographic research and mapping company based in Skokie, Illinois. RMAs include one or more central cities, satellite communities and suburbs, but unlike Metropolitan Statistical Areas (MSAs), are not restricted to following county boundaries.
