Growing anti-migrant protests in South Africa are creating concerns about violence, labour shortages and economic disruption. Demonstrators blame undocumented migration for unemployment, crime and pressure on public services, but businesses in construction, farming, retail and transport depend heavily on foreign workers. Thousands of migrants have reportedly considered leaving the country because of safety concerns. Economic research suggests migrant workers and migrant-owned businesses make a significant contribution to South Africa's economy. A larger departure could disrupt supply chains, reduce tax revenue and damage neighbouring countries that depend on money sent home by workers based in South Africa.
