More than 5,000 single family offices are now in operation around the globe, according to a pioneering investigation by Campden Research, whose lead author believes it is the most accurate estimation to date.
The total figure of 5,300 family offices is seated at the lower end of current estimates: professional services firm Ernst & Young reported at least 10,000 single family offices in its 2016 EY Family Office Guide, while wealth advisor Family Office Exchange believes there are 6,000 in the United States alone.
