More Britons left South Africa than arrived in most years between 1924 and 1928
Evidence
The following table of British immigration to and emigration from South Africa between 1924 and 1928 shows that Englishmen had a stronger inclination to leave the country than other immigrants and that, with one exception, each year showed a greater number of British people leaving the country than coming in: These figures are quoted from Leonard Barnes, Caliban in Africa. — Hannah Arendt, The Origins of Totalitarianism, 2309
