Representation Between 1967 and 2012

Constituencies created for the 1987 Elections

The number of constituencies remained at 158 up until 1986. Thus no additional units of representation were created for the 1969, 1974, 1979, and 1983 General Elections despite growing populations. Parliament ammended the Constitution via the Constitution of Kenya (Amendment) Act No 14 of 1986 that provided for a minimum of 168 and a maximum of 188 constituencies. Excerpts:

Subsequently the then elections body - the Electoral Commission of Kenya, ECK, carried out a delimitation of constituency boundaries to provide for an additional 30 Constituencies. Tables 3.1 - 3.8 below provide a breakdown of the new boundaries clustered under the eight Provincial Administrative units for purposes of perspective and context. During this period the number of administrative units known as Districts including Nairobi, remained at 41.
