The 2014 Kenya Demographic and Health Survey (KDHS) is a national sample survey that targeted 40,300 households designed to provide detailed information on aspects of health across Kenya and in each of the 47 counties. The KDHS is conducted every five years. The 2014 KDHS was the sixth survey of its kind to be conducted in Kenya, following those carried out in 1989, 1993, 1998, 2003, and 2008-09, and it is the first KDHS to provide information at the county level. In the 2014 KDHS, information was collected on household characteristics, education and employment, marriage and sexual activity, fertility levels and preferences, awareness and use of family planning methods, maternal and child health and survival, nutritional status, ownership and use of mosquito nets, knowledge and behaviours regarding HIV, domestic violence, female circumcision, and fistula.
