Percentage of Afrikaans speakers in three South African universities

An article here from a few months back gives some quick numbers to anyone curious:

North-West University (NWU) is now dethroning the University of Pretoria as the "largest Afrikaans university in the country". The latter has 16,400 Afrikaans-speaking students against NWU's 15,300...51% of its student body speaks Afrikaans while that for Tuks (UP) is just 36%. In Stellenbosch, the (previously) oldest Afrikaans university, 48% is Afrikaans.
