Delimitation of electoral divisions


The South Africa Act 1909 had provided for a delimitation commission to define the boundaries for each electoral division. The representation by province, under the third delimitation report of 1919, is set out in the table below. The figures in brackets are the number of electoral divisions in the previous (1913) delimitation. If there is no figure in brackets then the number was unchanged.[2]

The electoral divisions used for this general election were the same as those for the 1920 election.
