Record high fertility levels were recorded for Kenya in the late 1970's; however, a fertility reversal was experienced during the 1980's. Recent studies by Njoru, Robinson and the National Research Council and data from the 1989 and 1993 KDHS indicate that the fertility decline is real and pervasive. The release of the 1989 census data provides researchers with an additional source to document the fertility decline and to identify the spatial pattern of fertility reduction at the province and district level. The geography of fertility reduction is explored by addressing differences in the annual rate of population growth for each province and district.
