The research report on Kenya’s digital economy presents a brief history of the events and technological developments that lead to and shaped the digital revolution in Kenya since the 1990s until today. What follows is a collection of different measures of the digital economy in Kenya. Despite greatly varying estimates depending on data source and methodology, the general picture that emerges is that Kenya’s ICT sector is smaller than in most developed but larger than in many developing countries and has accounted for a substantial share of Kenya’s economic growth in the last 15 years, outperforming all other sectors in terms of GDP growth. The sub-sectoral analysis reveals that the internet access, mobile money, IT hardware and audio and video content (incl. broadcasting) markets are the largest sub-sectors.
