The analysis of financial institutions (FIs) by size was based on where consumers maintain their primary banking relationship. Note that consumers often have multiple relationships with various FIs; however, they can have only one primary relationship. FIs were divided into four categories determined by total deposits as of Dec. 31, 2015, according to rankings by American Banker:
- Giant national banks: deposits greater than $750 billion (JPMorgan Chase, Bank of America, Wells Fargo, and Citigroup)
- Large regional banks: $30 billion to $750 billion in deposits
- Small regional or community banks: less than $30 billion in deposits
- Credit unions: all credit unions
