This book is the result of over 10 years of research on thousands of companies - large and small, public and private - attempting to identify practices and policies century-old companies use to survive for the long term. The 2022 edition includes an updated list of Century Club Companies, through those founded in 1921. Even though a number of companies have been added since the last edition, the overall number of CCCs has remained fairly stable at around 1350. Of those dropping off the list (because they closed, were acquired, or broken up) 17% were public. This statistic is interesting because only 11% of CCCs overall are publicly-traded. The percentage of publicly-owned "old" companies has been steadily dropping since I first published my research in 2016. Another interesting statistic: 13% of the CCCs who have publicly-traded stock also have generational family members actively involved - in management and/or on the board.
