Sango, alongside with French, is the official language of the Central African Republic. This is unusual in sub-Saharan Africa, as many countries only have an European colonial language as their official language (like Togo, Gabon, or Mozambique) since it’s an effective lingua franca and prevents favouring one local language over another.
But in CAR, Sango has official status on the same level as French – mainly because almost the entire population speaks it, and it doesn’t “belong” to any one ethnic group. Sango is a creole, based originally off Ngbandi, but had been used as a trade language along the Ubangi river long before French colonization.
When the French founded Bangui as a trading hub on the Ubangi, Sango became the de facto language of the city, leading to a growing population that spoke it as their first language. While census data is spotty today, it remains a common first language in Bangui, and around 90% of CAR’s population can speak Sango as either a first or second language.
French still remains a prestige language and the language of higher education (as it is in the rest of former French Africa, including north Africa), and that also affects spoken Sango – the more formal the situation, the more French loanwords people use.

She also uses Central African songs as ways for learners to pick up Sango in context, including Idylle Mamba‘s music:
