From South Africa's Times Live we find this breakdown of the survey.
The SAIRR said Eastern Cape municipalities had the highest murder rate, 54 murders per 100,000 people, and a poverty rate of 62%.
But Limpopo municipalities recorded the lowest murder rate - while sharing the same poverty rate.
The findings form part of a local government study which assessed 80 indicators from each of 52 metropolitan and district municipalities.
The indicators included demographics, education, employment, housing, access to basic services, transport, social security, health, and crime.
Western Cape municipalities also recorded a high murder rate with a low poverty rate of 27.5%.
Poverty rates varied across municipalities, nationally and within provinces.
The Alfred Nzo District Municipality in the Eastern Cape recorded the highest poverty rate with 76%, while the lowest was in the West Coast Municipality and the Cape Winelands Municipality in the Western Cape.
