Who are Kenya’s 42(+) tribes? The census and the political utility of magical uncertainty

ABSTRACT The idea that Kenya is made up of 42(+) tribes is widespread, but the origins, nature and consequences of any list are not well-known. This article compares ethnic classifications in all Kenyan censuses to demonstrate the origins of the ‘42’ in (only) the 1969 census, and the multiple political purposes of classifying and counting. To make sense of why the 42(+) remains significant, I argue a cultivated vagueness provides a sense of consistency, linking a national past to present and future, while providing the basis for both numbers-based competitive politics and more inclusive politics. Moreover, it avoids engaging in politically risky work of making legible sense of shifts in ethnic identities, classifications and numbers, and avoids having to resolve their relation to the nation, which benefits both state and citizens. Extending literature on the political utility of uncertainty, I theorise this cultivated vagueness as magic, backed by opaque forces, potentially dangerous or beneficent, which deters interrogation or certainty on all sides. To further clarify this awkward relationship between vagueness and certainty, I argue ethnic classifications are intelligible via the social imaginary of the 42(+), but not especially legible, contesting the literature on census practices as tools of legibility and governability.
