Entrepreneur 2021 list of the Fastest Growing Franchises, published in the magazine's March issue. Celebrating its 50 th anniversary this year, the global industry leader currently boasts a network of 145,000 affiliated sales professionals in approximately 13,000 offices across 86 countries and territories worldwide. Achieving this top ranking further cements the CENTURY 21® brand's position as a global powerhouse not just within the real estate industry but among the world's top franchise companies across categories. Franchises on this list are ranked based on the net total of units (both franchised and company-owned) added globally from July 2019 to July 2020, with ties broken based on percentage growth. (In previous years, only US and Canadian unit growth was considered—2021 marks the first year that the ranking is based on systemwide growth, in recognition of the increasingly global nature of franchising.)
