7. Doesn’t medium density housing cause overcrowding?

No. Overcrowding is caused when there are too few housing units provided for the population or when housing is unaffordable. When there are not enough housing units or housing units are affordable, informal rental economies develop in backyards where families squeeze together in small shacks, or in overcrowded flats. If South Africa’s cities were well-planned and well-built to provide for all citizens, overcrowding would not be a problem.
