The Western Cape is the most protest-afflicted province so far this year, according to an independent local government and data intelligence organisation.
Municipal IQ economist Karen Heese says the Free State takes second place while the North West and Eastern Cape follow narrowly in a joint third position.
She said protest activity in Gauteng had dropped.
Heese said the highest number of monthly protests ever recorded on its Hotspots Monitor was registered in May.
She said protest action appeared to be the increasingly accepted way for communities to air grievances.
