Studies done by researchers show that entrepreneurial activities among women in Kenya are relatively lower than in developed countries. Studies done in other parts of Africa indicate that ownership of Co-operative Societies business is mainly by women aged between 30 and 45 years. This is mainly so because the women constitute about 32% of the population of Kenya of 33 million people, which is the current statistics.According to Okwoche 1998, 85% of women co-operators and 87% women non co-operators were between 31 and 50 years. He further says that the mean age for women co-operators was 38years and 40 years for women non co operators, an indication that the women were strong enough to take up farming as a vocation.This is the group that is active, creative, energetic that is able to bring about transformation into the nation. In this case, the studyis mainly concerned about women who are responsible, some in leadership positions, determined and are desirous to lead the nation into one that is economically stable and eventually self-reliant and sustainable.The study was therefore to determine the influence of motivation on performance of women enterprises, what the benefits of SACCOs on performance of on Kenyan women were, what the challenges of SACCOs on performance of women enterprises were, what the effects of these challenges on women enterprises were and the conceptual framework, toestablish what motivated Kenyan women to engage in co-operative activities as they ran their businesses. The study was to identify co operative activities undertaken by Kenya women, to investigate benefits of SACCOs to women enterprises in Kenya and to determine challenges faced by Kenya women enterprises.The women of today are gradually taking up responsible roles in the society and the nation. This has led to the involvement of government in order to support the women so that they can be an asset to the nation and the community in which they leave. By so doing, the women have been encouraged to engage in entrepreneurial activities. This research project was therefore to study the impact of Savings and Credit Co-operative Societies on performance of women enterprises in Nairobi County. The research was conducted using descriptive method of research.
