Total revenue is the most complete measure of a club’s scale available from public filings because it captures every revenue source in a single line: dues, initiation fees, investment income, greens fees, dining, events, and rental income. Clubs that appear unusually large relative to their membership often carry significant investment portfolios — endowments accumulated over decades — whose returns flow through the revenue line. At the top of this table you will generally find multi-amenity operations with golf, tennis, dining, and aquatics, serving memberships of several hundred families. Year-over-year swings of more than 10% typically reflect a single large initiation-fee class or a material change in investment returns rather than operational growth.
