Concentration, 1994–2025
Branch-count HHI squares each institution’s share of the county’s branch offices; deposit HHI squares its share of county deposits. The bands are the 2010 Horizontal Merger Guidelines classification, the dashed line the 1,800 level above which the Federal Reserve reviews a merger centrally. In 2025 this market is unconcentrated on branches (892) and highly concentrated on deposits (4,277).
