Teasing out crime trends from crime statistics is often bewildering, with some crime types going up and others down. The delayed releases by the South African Police Service (SAPS) also mean that what the nation is currently experiencing is not always what is reflected in the data. We are now in the part of the year where crime tends to rise, so it feels as if “things are getting worse”.
But the signal coming from the data to September was that we may have turned the corner on violent crime. In an environment of low and variable trust in policing, which in turn affects reporting rates, which in turn makes the trends in crimes such as sexual offences difficult to interpret, murder is a strong signal to look at. This is because an increase in reported sexual offences could mean survivors are reporting more — perhaps because of better response via interventions such as Thuthuzela Care Centres.
Or it could mean that there are, in fact, more sexual offences. It is difficult to discern which interpretation is more at play. This was sustained for the first full year (July 2024 to June 2025), and indeed accelerated in the quarter to September.

What drove this trend, and will it continue? A clue can be found in the trends for the years immediately before the formation of the GNU. After the Covid-19 lockdown ended, murder accelerated, and once load-shedding took hold in earnest, this trend was amplified.
However, around this time it became noticeable in the data that the Western Cape began to diverge in quarterly trends from the rest of the country. Before, it had closely mirrored the national seasonal trends, albeit at a higher level. What are the candidate reasons for the diversion?
There are obvious consequences of load-shedding that might worsen crime. This includes crime effects arising from, among other things, street lights and security devices not working, and restricted deployment due to lack of electricity. Though load-shedding affects the whole country, Cape Town was able to protect its customers from one or two stages via the Steenbras hydroelectric scheme.
The city supplies electricity to about 70% of its residents, which in turn comprise 66% of the provincial population. Analysis in mid-2024 revealed that in the Western Cape, there has been no relationship between the national number of days of load-shedding and the murder rate. However, for the rest of the country, the number of load-shedding days per quarter was statistically significantly associated with the number of murders per quarter, with 32% of the variation in murder predicted by the number of load-shedding days, and every additional load-shedding day in a quarter being associated with 20 extra murders.
Load-shedding ended abruptly in May 2024. In the first quarter of the GNU, which was also the first quarter of no load-shedding, the number of murders dropped by 1,151, an incredible 17% compared with the same quarter the previous year. But in the same quarter the previous year there had been 74 days of load-shedding.
The absence of those 74 days could accordingly account for much of the change. Some lack of load-shedding effects are longer term, so further reductions can be expected. Indeed, the entire first year of the GNU recorded lower murders, with the total reduction a staggering 3,145, an 11% decrease in the murder rate.
