In the year ended March 2017, there were 20,336 murders and the murder rate was 35.9 per 100,000 – over five times higher than the global average of 6.2 per 100,000. More than 526,000 South Africans were murdered from 1994 to 2019. Middle-class South Africans seek security in gated communities. The private security industry in South Africa is the largest in the world, with nearly 9,000 registered companies and 400,000 registered active private security guards, more than the South African police and army combined. Many emigrants from South Africa also state that crime was a major factor in their decision to leave. Crime against the farming community has continued to be a major problem. In an attempt to reduce crime rate, the police arrested over 500 undocumented foreigners in a raid in August 2019.
