The regional hub for trade and finance, Kenya's business sector is one of Africa's most vibrant. It is the transport and broadband gateway to the landlocked countries of East Africa. The country is far less dependent on official development assistance than most other Sub-Saharan countries, aid amounting to only 4 percent of GDP. Kenya faces the challenges of rapid demographic growth: 43 percent of its population is under 15 years of age. Entrepreneurship and small business growth is key in providing jobs for the young population and keeping the economy healthy and strong.
