After the boer war, the majority population of south africa was forced to live

Many South Africans had to live in make-shift shelters such as tents after war.  This was due to the scorched earth policy that the British used against Boer commandos that led to the weakening of their resolve.  Prior to this, families were also rounded up and placed in camps guarded by the British which demoralized the Boers.

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]
