Most South Africans are multilingual, and English is commonly used (especially in urban areas. Rural tend to skew Afrikaans). "English is South Africa's lingua franca, and the primary language of government, business, and commerce"[1]

However, only 9.6% of the population use English as their first ('home') language. Zulu has the highest proportion with 22.7%
