With social security provisions in Kenya remaining under-reported in the more recent literature, this overview covers recent reforms in key areas of the country's social security system. In the health sector and in old-age pension provision social security is still mainly workerist (biased toward those in formal employment), and attempts to expand coverage have had limited effect only -cash transfer programmes, for instance, have been expanded but in practice they do not universally cover the entitled categories. Thus, although the Kenyan social security system now has a considerable propoor social assistance component it remains biased toward those in formal employment, to the benefit of the highest income quintile.
