This report examines the voting trajectories of individuals in five metropolitan municipalities: City of Johannesburg, City of Tshwane, eThekwini, City of Cape Town, and Nelson Mandela Bay. It is based on a telephone survey of 3,905 residents in these five municipalities who were eligible to vote in the 2021 local government elections, conducted in the days immediately following the election. The survey asked voters to indicate which party they voted for in the 2021 local government election, as well as who they voted for in the 2016 local government election and the 2019 national government election. Some respondents refused to indicate their voting decisions at some or all of the elections. The sample sizes thus include the following: 2,777 in 2016; 2,787 in 2019, and 2,820 in 2021. The findings presented in this report are representative of the South African population in the five municipalities noted above. They demonstrate growing fluidity within the South African electorate, as indicated by movement between different parties, and by movement from electoral participation to abstention, across the three elections.
