Tables 2.1 and 2.2 summarize the changes over time in the population shares of tribes that did and did not have their own Native Authorities. Table 2.1 records the changes in these population shares between 1930/33, shortly after Indirect Rule began, and 1962, the year before it ended. Table 2.2 records changes in tribal population shares between 1930/33 and 1990, when, for the first time, data on self-reported tribal identifications became available. Both tables report only aggregate figures for tribes with and without Native Authorities. Tables A.1 and A.2 break down the figures for the individual tribes in each category for the 1930/33–1962 and 1930/33–1990 periods, respectively.

As Tables A.1 and A.2 make clear, individual tribes within each category vary in the changes that took place in their shares of the national population during each period. Although the population share of all tribes that had their own Native Authorities increased by 6.7 percent between 1930/33 and 1962, the degree of change experienced by individual tribes in this category ranged from +140 percent for the Luchazi to −83 percent for the Chikunda (see Table A.1). Similarly, while the population share of tribes that did not have their own Native Authorities fell during the same period by a weighted average of 28.5 percent, individual tribes in this category varied in their population growth or decline from +304 percent for the Kwandi to −95 percent for the Lushange.
